Choosing a 2S LiPo Battery for the Redcat SixtyFour-18
The Redcat SixtyFour-18 brings the classic 1964 Chevrolet Impala SS lowrider experience into a compact 1/18-scale RC platform. From smooth indoor cruising to three-wheel motion and front-end hopping, its appeal comes from precise, controlled movement rather than outright speed.
The SixtyFour-18 comes equipped with a 7.4V 750mAh 2S LiPo battery. For owners shopping for a spare or considering additional battery capacity, the main priorities are straightforward: stay with the correct 2S voltage, choose a compact pack, pay attention to battery weight, and ensure a secure electrical connection.
A 900mAh 2S LiPo is an attractive capacity class to consider because it offers a modest increase in stored energy without jumping to the larger batteries normally associated with high-speed RC cars. The goal is to extend enjoyment of the lowrider while preserving the characteristics that make it fun to drive and hop.
Redcat SixtyFour-18 Stock Battery Specifications
The factory battery establishes a useful baseline for choosing an alternative. The SixtyFour-18 uses the same 2S 750mAh LiPo battery type found in the Redcat Ascent-18, making compact crawler-style LiPo packs a relevant starting point for battery selection.

| Connector Configuration | PH2.0 / JST; see individual product specifications |
| Balance Connector | JST-XH |
| Package | 2 Packs |
The two-pack configuration is particularly convenient for a small indoor lowrider. Instead of interrupting a session to recharge, owners can keep a second properly charged battery available. This is useful for casual cruising, tabletop demonstrations, and longer RC hobby sessions.
As with any aftermarket RC battery, match the pack dimensions, connector and polarity to the vehicle before installation.
750mAh vs 900mAh: How Much Difference Does Capacity Make?
Battery capacity determines how much electrical charge a pack can store. At the same nominal voltage, moving from 750mAh to 900mAh increases the available nominal energy from approximately 5.55Wh to 6.66Wh.
| Specification | Original 750mAh | CNHL 900mAh |
|---|---|---|
| Voltage | 7.4V | 7.4V |
| Cell Count | 2S | 2S |
| Capacity | 750mAh | 900mAh |
| Nominal Energy | 5.55Wh | 6.66Wh |
| Capacity Increase | Baseline | 20% |
| Main Advantage | Factory battery configuration | Additional nominal energy |
For the SixtyFour-18, extra capacity is mainly about having more energy available for cruising and operating the suspension system. Actual runtime will vary depending on the frequency of hopping, servo movement, driving conditions, and battery condition.
The car's slow-speed, scale-oriented nature also means that battery selection should not be driven by an exceptionally high discharge rating. A dependable 2S battery with suitable physical dimensions is more relevant than an oversized racing pack.
Battery Size, Weight and the SixtyFour-18's Rear-Mounted Layout
One detail that makes the SixtyFour-18 different from many small RC cars is its rear-mounted battery arrangement. The vehicle's weight distribution is part of the way its suspension and hopping movements work, so battery size and weight deserve attention alongside capacity.
A compact, securely mounted battery helps keep wiring away from moving suspension parts and preserves the intended arrangement inside the chassis. A substantially larger or heavier battery can change how weight is carried and how the vehicle responds during body movement.
When choosing an alternative pack, focus on three practical considerations:
- Physical dimensions: the pack must fit the battery mounting area with enough room for wiring and body clearance.
- Installed weight: avoid unnecessary mass that could change the car's hopping characteristics.
- Secure placement: keep the battery firmly positioned and clear of suspension linkages and other moving components.
The ideal Redcat SixtyFour-18 battery upgrade is therefore not necessarily the largest pack available. A well-matched compact battery is a more practical choice for a miniature lowrider whose main attraction is controlled movement.
JST and PH2.0 Battery Connectors: Check Before Installation
Redcat's 750mAh 2S replacement battery used in the Ascent-18 is supplied with a JST connector. When choosing an aftermarket battery for the SixtyFour-18, compare the actual battery-side and vehicle-side connectors rather than relying on capacity and voltage alone.
Connector names matter because JST and PH2.0 are not automatically interchangeable. Check the mating connector type and polarity before connecting a new battery. The connector must fit correctly without being forced, and the wiring must be suitable for the vehicle's electrical system.
A matching 2S battery voltage is essential, but a matching physical and electrical connection is equally important for a trouble-free installation.
Charging and Maintaining Your 2S Lowrider LiPo Battery
The Redcat SixtyFour-18 includes a USB charger for its factory LiPo battery. For aftermarket packs, use a charger compatible with the battery's cell count, chemistry, charge connector, and specified charging current.
A standard 2S LiPo reaches 8.4V at full charge, or 4.20V per cell. For a 900mAh battery, a 1C charge rate is equivalent to 0.9A when supported by the battery and charger. Never exceed the battery manufacturer's recommended limits.
For regular RC use, a dedicated LiPo battery charger with an appropriate 2S balance-charging mode provides greater control over charging current and individual cell voltage.
Always inspect batteries before charging, use a fire-resistant charging setup, never leave charging unattended, and place packs at a suitable storage voltage when they will not be used for an extended period. For more detailed charging instructions, see our LiPo Battery Charging Guide.
