Batteria Proboat Blackjack 24 – La migliore LiPo 2S per Pro Boat Blackjack 24 V2

Best Battery for the Proboat Blackjack 24 V2 Brushless Catamaran

The best battery setup for the Proboat Blackjack 24 is a pair of closely matched 2S LiPo batteries installed in the boat’s left and right SSL trays. The two packs connect in series to power the stock 4S brushless system, so both batteries should be identical in capacity, dimensions, weight, chemistry, age and condition.

The official recommendation for the Pro Boat Blackjack 24 V2 is two 2S 5000mAh 100C LiPo batteries. CNHL expands that baseline with compatible 5600mAh, 6000mAh and 8000mAh EC5-equipped options for owners who want to prioritize balanced performance, lower battery weight or longer runtime.

Proboat Blackjack 24 Battery Requirements at a Glance

Why the Blackjack 24 Proboat Setup Uses Two 2S Batteries

The Blackjack 24 does not use one centrally mounted 4S battery. Instead, one 2S pack sits on each side of the catamaran hull. The boat’s wiring connects those two batteries in series, adding their voltage together while keeping the capacity unchanged.

For example, two 5600mAh 2S batteries create a 4S 5600mAh power system. They do not create a 4S 11200mAh system.

The dual-pack arrangement also distributes battery mass between the two sides of the hull. That is especially important in a high-speed RC catamaran because unequal left-and-right weight can affect straight-line tracking, corner entry, wake response and the way the boat lands after becoming light over the water.

Do not combine two different capacities or mix an older battery with a new one. A weaker pack can reach low-voltage cutoff first, even when the other battery still has usable energy remaining.

Three Recommended CNHL Batteries for the Pro Boat Blackjack 24 V2

Best Overall: CNHL Racing Series 5600mAh 7.4V 2S 120C

The CNHL Racing Series 5600mAh 2S2P 120C hardcase battery is the strongest all-around starting point for most Proboat Blackjack 24 owners. Its capacity remains close to the factory 5000mAh recommendation while providing additional energy reserve for repeated acceleration and longer passes.

Each pack measures approximately 139 × 47 × 25mm and weighs about 292g. A matched pair therefore weighs approximately 584g.

This setup delivers a practical middle ground between the lighter 6000mAh LiHV combination and the heavier 8000mAh option. It is also a conventional 7.4V LiPo battery, so charging and voltage management remain straightforward for owners who do not need LiHV operation.

Choose the 5600mAh pair when you want:

• A capacity close to the official 5000mAh specification
• Standard 4.20V-per-cell LiPo charging
• Strong 120C current capability
• A balanced compromise between installed weight and runtime
• A straightforward first battery setup for the stock boat

Lightweight Performance: CNHL LiHV 6000mAh 7.6V 2S 120C

The CNHL Racing Series LiHV 6000mAh pack is the lightest of the three primary recommendations despite offering more capacity than the 5600mAh option. Each battery measures approximately 138 × 47 × 23mm and weighs about 239g.

A pair weighs approximately 478g, which is around 106g lighter than the recommended 5600mAh combination. In a 24-inch performance boat, that difference is significant enough to influence acceleration, throttle response and how quickly the hull reacts when crossing small wake.

Lower battery mass does not guarantee a higher top speed, but it reduces the weight that the stock 3660 motor must accelerate. The boat may feel more responsive when transitioning onto plane and when power is reapplied after a turn.

This is a LiHV battery with a nominal voltage of 7.6V per pack. The battery itself can support LiHV charging, but the stock Blackjack 24 V2 is officially specified around conventional 2S LiPo batteries. Unless Pro Boat or Spektrum explicitly confirms full 4.35V-per-cell operation for the complete stock system, charge these packs to a maximum of 4.20V per cell for use within standard 4S LiPo voltage.

Choose the 6000mAh LiHV pair when you want:

• The lowest installed battery weight of the three recommendations
• A thinner 23mm hardcase profile
• Responsive acceleration and reduced hull mass
• 6000mAh capacity without the weight of the larger packs
• Strong real-world voltage support under load

Longest Runtime: CNHL Racing Series 8000mAh 7.4V 2S 120C

The CNHL Racing Series 8000mAh 2S 120C battery is the capacity-focused option for drivers who prefer longer running sessions and fewer trips back to shore for battery changes.

Each EC5-equipped pack measures approximately 139 × 47 × 25mm and weighs about 318g. A matched pair weighs approximately 636g, making it around 52g heavier than the 5600mAh setup and 158g heavier than the 6000mAh LiHV setup.

The additional capacity gives the boat more stored energy, but runtime will not increase in a perfectly linear ratio. The heavier setup requires more power during acceleration and can change how the catamaran responds to its own wake, short waves and sudden direction changes.

The 8000mAh combination makes the most sense for broad water, longer sweeping passes and drivers who value time on the water more than minimum installed mass. It should not automatically be treated as the fastest setup simply because it has the largest capacity.

Choose the 8000mAh pair when you want:

• The greatest energy reserve of the three recommendations
• Fewer battery changes during a lake session
• Longer straight-line and open-water running
• Conventional 7.4V LiPo charging
• A higher-capacity alternative that retains the same 47mm case width

Pro Boat Blackjack 24 V2 Battery Size and SSL Tray Fit

The Blackjack 24 V2 uses Pro Boat’s SSL system, short for Strap, Slide and Lock. Each battery is secured to a removable tray before the tray is inserted into the hull.

This system provides several practical advantages:

• The battery can be strapped down outside the narrow hull
• The pack is less likely to move during acceleration, wake impacts or a flip
• The fixed IC5 connectors remain easy to reach
• Battery wires are less likely to move around the drivetrain
• Left and right installation becomes more repeatable between runs

The selected 5600mAh, 6000mAh and 8000mAh packs are all approximately 47mm wide. The 5600mAh and 8000mAh packs use a 25mm case height, while the lighter 6000mAh LiHV pack is approximately 23mm high.

Battery dimensions and weight can vary slightly between production batches. Before the first run, confirm clearance around the tray locks, straps, labels, balance leads, main wires and fixed connector holders.

How Battery Weight Changes Blackjack 24 Handling

The Pro Boat Blackjack 24 V2 is a high-speed catamaran rather than a heavy Deep-V hull. As speed increases, the boat reduces its wet surface and rides mainly on the rear running pads while air travels through the center tunnel.

This makes battery weight an important part of the setup:

• Lighter batteries reduce acceleration load and can make the boat react more quickly to throttle changes.
• Medium-weight batteries provide a balanced combination of energy reserve and predictable hull response.
• Heavier batteries provide more runtime but add momentum when the boat hits wake, turns or lands after becoming airborne.

A heavier setup is not always more stable. It may feel more planted in some straight-line conditions, but it also asks the hull, rudder and drivetrain to control more mass during abrupt direction changes.

For most owners, the 5600mAh combination is the safest starting point. The 6000mAh LiHV pair is better suited to drivers who want lower mass, while the 8000mAh pair is best reserved for drivers who understand the runtime-versus-weight tradeoff.

EC5 Batteries with the Factory IC5 Connectors

The Blackjack 24 V2 has two hard-mounted IC5 device connectors. The recommended CNHL batteries in this collection use EC5 plugs.

EC5 and IC5 are physically compatible. The EC5 battery plug can connect directly to the factory IC5 device connector without a separate power adapter, provided the plug is inserted with the correct orientation and polarity.

EC5 provides the positive and negative high-current connection needed to operate the boat, but it does not include Spektrum Smart battery electronics. As a result:

• The battery can power the stock motor and ESC normally
• No connector adapter is required
• The ESC can still perform its normal control functions
• The battery will not automatically identify itself as a Smart battery
• Battery chemistry, cell count and charge current must be selected manually on the charger

The included SLT2 radio system also does not display the full Smart telemetry available through an upgraded compatible Spektrum receiver and transmitter.

How to Install Two Batteries in the SSL Trays

1. Remove both SSL battery trays from the hull.
2. Inspect both batteries for swelling, damaged wires or connector wear.
3. Place one matching 2S battery on each tray.
4. Tighten the straps so the packs cannot slide forward, backward or sideways.
5. Keep the balance leads and main wires away from tray locks and moving parts.
6. Slide both trays completely into their locked positions.
7. Confirm that the batteries sit symmetrically on the left and right sides.
8. Connect both EC5 plugs to the factory IC5 connectors.
9. Check that no wire can contact the motor coupler or flex shaft.

The SSL trays make battery installation clean and repeatable, but their fixed position also limits fore-and-aft battery movement. Advanced owners therefore have less freedom to adjust center of gravity by sliding the packs than they would with a traditional open battery platform.

How to Drive the Pro Boat Blackjack 24 More Reliably

The Blackjack 24 V2 is capable of strong straight-line speed, but a performance catamaran should not be held at full throttle through every corner.

A more reliable driving sequence is:

1. Build speed progressively on the straight.
2. Reduce throttle before entering the turn.
3. Allow the hull to settle and regain clean contact with the water.
4. Use a smooth steering input rather than an abrupt full-lock command.
5. Roll the throttle back in as the boat exits the corner.

This technique becomes more important when the water is choppy or when the boat must repeatedly cross its own wake. Air entering the center tunnel can make the hull feel light, while water inside the hull can change the balance later in the run.

If the bow begins moving repeatedly up and down, first check battery seating, left-to-right balance, water inside the hull and water conditions. Propeller choice and small strut adjustments can also affect porpoising, but hardware changes should be made gradually and tested one at a time.

Does the Proboat Blackjack 24 Have Self-Righting?

No. The Pro Boat Blackjack 24 V2 does not have a self-righting system. If it lands upside down, it normally remains inverted until it is recovered.

Before running, prepare a safe recovery method such as:

• A small recovery boat
• A fishing line with a safe retrieval attachment
• A kayak used only where conditions and local rules permit
• Running close enough to shore for controlled retrieval

Do not swim into deep, cold, fast-moving or otherwise unsafe water to retrieve an RC boat. The absence of self-righting makes controlled corner entry and battery reliability especially important because a power loss or flip far from shore can end the session.

Proboat Blackjack 24 Upgrades: Stock 4S vs. Modified 6S

The stock Blackjack 24 V2 is designed around two 2S batteries, a 4S total voltage and a 90A marine ESC. The batteries in this collection are selected for that intended stock configuration.

Some modified Blackjack 24 builds use two 3S batteries for a 6S system, but this is not a battery-only upgrade. A proper 6S conversion may require:

• A suitable 6S-capable marine ESC
• Two matched 3S batteries
• Revised propeller diameter and pitch
• Cooling-system checks
• Motor-temperature monitoring
• Drivetrain and coupler inspection
• New strut and hull tuning
• Shorter high-load passes

Do not install two 3S batteries on the stock ESC simply because they fit the trays. High-speed 6S results reported by modified owners should not be treated as evidence that the original boat is plug-and-play compatible with 6S power.

Battery Charging and Pair Management

Charge each battery with a compatible balance charger using the JST-XH balance connector. The two batteries should finish charging at closely matched voltages before they are installed in series.

For the conventional 7.4V LiPo options:

• Select 2S LiPo balance charge mode
• Use a maximum final voltage of 4.20V per cell
• Confirm both cells remain closely balanced

For the 7.6V LiHV option:

• The battery is capable of LiHV charging
• Full LiHV charge voltage is 4.35V per cell
• The complete stock boat is officially specified for conventional 2S LiPo packs
• Use a 4.20V-per-cell limit unless full LiHV voltage has been confirmed for the stock system

Never connect one fully charged battery in series with a partially charged battery. Stop using a pair if one pack becomes significantly warmer, sags earlier or shows a larger cell imbalance than the other.

Blackjack 24 Battery and Boat Maintenance

After each run, disconnect and remove both batteries before servicing the boat. Inspect the packs for swelling, impact damage, wet connectors, damaged insulation or unusual heat.

Open the hull drain and remove any accumulated water. Dry the battery trays, connectors, receiver-box area and wiring before storage. Check that both cooling outlets produced visible water flow during operation.

The rear grease port simplifies routine lubrication around the prop-strut bushing, but it does not eliminate normal flex-shaft care. Periodically remove the flex shaft, wipe it clean, inspect it for wear or corrosion, allow it to dry and apply suitable marine grease before reassembly.

Store the batteries separately from the boat at an appropriate storage voltage when they will not be used for several days.

Pro Boat Blackjack 24 V2 Battery FAQ

What battery does the Proboat Blackjack 24 use?

It uses two matching 2S LiPo batteries connected in series. The official recommendation is two 5000mAh 100C packs, creating a stock 4S power system.

Do I need two batteries for the Pro Boat Blackjack 24 V2?

Yes. The intended setup uses one 2S battery on each side of the hull. Two matched packs provide the correct 4S voltage and help preserve left-to-right balance.

Can I use one 4S battery instead?

A single 4S pack is not the recommended CNHL setup. The factory SSL trays, dual connectors and hull balance are designed around two separate 2S batteries.

Can I use EC5 batteries with the stock IC5 connectors?

Yes. EC5 and IC5 are physically compatible for the main power connection. A conventional EC5 battery will not provide Spektrum Smart battery identification or Smart battery data.

Can I mix a 5600mAh battery with an 8000mAh battery?

No. Both batteries should be the same model, capacity, chemistry, age and condition. Mixing packs can cause one battery to reach low voltage earlier than the other.

Which battery is best for the Blackjack 24 V2?

The 5600mAh 7.4V pair is the best overall recommendation. Choose the 6000mAh LiHV pair for lower installed weight or the 8000mAh 7.4V pair when longer runtime is the main priority.

Will a higher C rating automatically make the boat faster?

No. A battery with low internal resistance and good voltage retention can improve acceleration and loaded voltage, but the printed C rating alone does not guarantee a particular speed. Battery condition, weight, propeller setup, water conditions and hull tuning also matter.

Can the stock Blackjack 24 V2 run on 6S?

The stock boat is configured for 4S power. A 6S build should be treated as a custom modification involving the ESC, batteries, propeller, cooling and drivetrain rather than as a direct battery substitution.

Does the Blackjack 24 V2 self-right after a flip?

No. Prepare a safe recovery method before running, especially on larger water or in windy conditions.
