Quick Fit Check
The CNHL G+Plus 5000mAh 29.6V 8S 70C LiPo battery with QS8 plug is a complete single-pack 8S power solution for large EDF jets, RC airplanes, helicopters, high-power vehicles, boats and custom electric models.
Unlike an 8S setup created from two 4S batteries connected in series, this pack provides the full 8S 5000mAh configuration in one battery. That means one main battery, one balance connector and no need to match two separate 4S packs for age, condition, internal resistance and charge level during operation.
Before ordering, confirm that the model can accommodate a 145 × 51 × 64mm battery weighing approximately 981g. This battery uses a QS8 connector, so models equipped with EC5, IC5, XT90 or another connector require a properly rated adapter or professional connector conversion.

Single-Pack 8S Power Without a Series Harness
The CNHL G+Plus 5000mAh 8S battery provides the same basic voltage and capacity configuration as two matched 4S 5000mAh batteries connected in series: 8S 5000mAh.
A dual-4S setup requires two batteries of the same model, capacity, age, condition, internal resistance and charge level, together with a correctly rated series harness. This single 8S pack removes the series connection and keeps the complete power source within one battery assembly.
This can simplify charging records, installation and pre-flight battery management. However, the charger must support an eight-cell LiPo battery, and the model must have enough uninterrupted space for the complete 145mm-long pack.
Why Choose This Battery?
Complete 8S voltage in one pack
The single-pack layout avoids the additional connector, wiring and possible pack-to-pack imbalance involved in a two-battery series installation. It is particularly useful for models with one large battery compartment rather than two separate trays.
Balanced 5000mAh capacity
The 5000mAh capacity provides a practical balance between available energy and installed weight for many large EDF and high-power 8S systems. A larger-capacity pack may offer more runtime but can also increase center-of-gravity, takeoff-weight, chassis-balance and battery-space concerns.
70C output with heavy-gauge wiring
The 70C continuous discharge rating, 140C burst rating and 8AWG main wires are intended for demanding power systems that require substantial current during acceleration, takeoff, vertical maneuvers or high-load operation.
QS8 connector for high-current installations
The QS8 connector provides a robust main power interface for large electric RC systems. Connector type alone does not confirm model compatibility, so polarity, current rating, cable direction and physical clearance must be checked before use.
Single-Pack 8S Battery for the Freewing Ares 3D 90mm EDF Jet
The CNHL G+Plus 5000mAh 8S 70C battery is a proven single-pack power option for the Freewing Ares 3D Ultra Performance 8S 90mm EDF Jet.
Instead of using two separate 4S 5000mAh batteries and an EC5 series harness, this pack supplies the complete 8S 5000mAh configuration from one battery. Its power delivery provides the throttle authority needed for demanding thrust-vectoring flight, including establishing a stable hover and retaining enough reserve to pull away from it confidently.
The aircraft uses an EC5 power connection, while this battery has a QS8 plug. A correctly rated QS8-to-EC5 adapter or professional connector conversion is therefore required. Confirm polarity, connector clearance, lead direction, battery retention and the final center of gravity before flight.

Single-Pack 8S Option for the Freewing Eurofighter Typhoon V2
The CNHL G+Plus 29.6V 8S 5000mAh 70C LiPo battery with QS8 is also a single-pack alternative for the Freewing Eurofighter Typhoon V2 8S High Performance 90mm EDF Jet.
It provides the complete 8S voltage and 5000mAh capacity in one battery, avoiding the need to charge, match and install two separate 4S packs. This is a practical direction for experienced pilots who prefer simpler single-pack battery management.
The Eurofighter's standard power connection uses EC5, so this QS8 battery is not a direct plug-in installation. A correctly rated QS8-to-EC5 adapter or connector conversion is required.
Before flight, confirm the 145 × 51 × 64mm dimensions, approximately 981g installed weight, battery position, lead direction, connector clearance, hatch closure, secure retention and final center of gravity. The adapter, connectors and wiring must be suitable for the current demands of the installed 90mm EDF system.

Compatible RC Models and Applications
Large 8S EDF Jets
This battery is well suited to large 8S EDF jets that can accommodate a single 981g battery. Confirm battery-bay dimensions, center of gravity, ESC voltage rating, cooling, intake clearance, wire routing, takeoff weight and landing behavior.
Large RC Airplanes and 3D Aircraft
The 8S voltage and 70C output can support large sport, scale and aerobatic aircraft. Check the recommended battery range, motor KV, propeller current, ESC limit, center of gravity and secure battery retention.
700–800 Class RC Helicopters
The pack may be used in compatible large helicopters with a single-pack 8S power system. Confirm frame clearance, strap position, cable routing, motor and ESC specifications, head-speed setup and final balance.
Large FPV and Multicopter Platforms
Custom X-Class, X8 and other large multicopter builds may use this battery when the airframe, propulsion system and flight controller are designed for 8S operation. Check all-up weight, motor KV, propeller clearance, ESC rating, voltage sag, battery mounting and expected flight time.
1/7 and 1/8 Scale RC Vehicles
The battery may suit high-power 8S vehicles with one sufficiently large battery tray. Confirm tray dimensions, battery-door clearance, QS8 connection, strap security, chassis balance, ESC voltage rating and driveline clearance. Vehicles designed around two separate 4S trays may not accept one large 8S pack.
High-Power RC Boats
For compatible 8S boats, check tray size, hatch clearance, hull trim, symmetrical placement, cooling, waterproofing, wire routing, battery retention and self-righting behavior. The approximately 981g installed weight must be positioned without creating poor hull balance.
QS8 Connector and Conversion Notes
This battery is supplied with a QS8 output connector. It cannot be connected directly to EC5, IC5, XT90, XT60, T/Dean, TRX or Traxxas iD power systems.
When the model uses another connector, use a properly rated adapter or professional connector conversion. Confirm connector polarity, continuous current capability, contact condition, cable direction and available clearance before connecting the battery.
Adapters add another electrical connection and may also add wire length and resistance. For high-current EDF, aircraft, car or boat systems, the adapter and its wiring must be appropriate for the actual operating current rather than selected only because the connector ends physically match.
Single 8S Pack vs. Two 4S Packs in Series
| Setup |
Result |
Main Consideration |
| One 8S 5000mAh pack |
8S 5000mAh |
Simpler single-pack installation, but requires an 8S-capable charger and one large battery space. |
| Two 4S 5000mAh packs in series |
8S 5000mAh |
Requires two matched packs and a correctly rated series harness but can suit divided battery trays. |
Series wiring doubles voltage while capacity remains unchanged. Two 4S 5000mAh batteries connected in series create 8S 5000mAh, not 8S 10000mAh.

FAQ
What is the main advantage of a single 8S battery?
A single 8S battery provides the complete voltage and capacity in one pack. It removes the need to match two separate 4S batteries and eliminates the external series harness, although it requires a charger capable of balancing eight cells.
Can this battery be used in the Freewing Ares 3D 8S?
Yes. It is a proven single-pack option for the Freewing Ares 3D Ultra Performance 8S 90mm EDF Jet. Because the aircraft uses EC5 and the battery uses QS8, a correctly rated QS8-to-EC5 connection solution is required.
Can it be used in the Freewing Eurofighter Typhoon V2 8S?
Yes. It can be used as a single-pack 8S 5000mAh alternative when the battery dimensions, weight and final center of gravity are confirmed. A QS8-to-EC5 adapter or connector conversion is required for the aircraft's EC5 power connection.
Is QS8 directly compatible with EC5 or IC5?
No. QS8, EC5 and IC5 are different connector systems. A properly rated adapter or connector conversion is required, with polarity and current capability checked before use.
Does one 8S 5000mAh battery equal two 4S 5000mAh batteries in series?
Electrically, both configurations provide 8S 5000mAh. The difference is the physical installation: one complete 8S pack versus two matched 4S packs connected through a series harness.
Can a standard 6S charger charge this battery?
No. The charger must support at least eight LiPo cells and must be able to balance the JST-XH-9P connection through a compatible charger port or balance board.
Should the battery always be charged at 5C?
No. The 5C figure is the specified maximum charge rate, not the required everyday rate. A lower balanced charge rate generally creates less heat and places less stress on the battery.
