9000mAh 3S2P LiHV Battery for High-Load RC Systems
The CNHL Racing Series 9000mAh 3S LiHV battery combines a large energy reserve with a high-output 3S2P cell configuration. It is designed for RC applications where sustained current delivery and long operating time are more important than minimizing battery weight.
The 3S2P construction uses three cell groups connected in series for 11.4V nominal voltage, with two parallel cells within each group contributing to the total 9000mAh capacity and current capability. This allows the pack to support demanding surface and aircraft power systems while retaining a practical 139mm case length.
One pack provides a 3S 9000mAh system. Two matched packs can create a 6S 9000mAh series setup, while four matched packs can form a 12S 9000mAh system. Series wiring increases voltage but does not increase capacity.
Why Choose This Battery?
-
9000mAh capacity: Provides a large energy reserve for extended street runs, speed sessions and high-power aircraft applications.
-
Strong voltage delivery: The 120C rating, 10AWG wires and EC5 connector support demanding acceleration and sustained electrical loads.
-
139mm case length: Delivers substantial capacity without using an unusually long battery format.
-
Flexible system building: Use one pack for 3S, two matched packs for 6S or four matched packs for a custom 12S installation.
-
LiHV chemistry: Supports up to 4.35V per cell when the ESC and charger are compatible with the higher fully charged voltage.
ARRMA FELONY 6S Battery Setup
Two matched CNHL Racing Series 9000mAh 3S LiHV batteries can be connected in series to create a 22.8V nominal 6S 9000mAh setup for the ARRMA FELONY.
The paired battery system provides strong voltage support during hard acceleration, high-speed street driving and power-induced drifting. In this setup, the car can break traction rapidly from a standing start and maintain strong power delivery under the heavy current demand of the 1/7-scale drivetrain.
Each pack measures 139 × 47 × 37mm and weighs approximately 498g, giving a combined battery weight of about 996g. The EC5 plugs are physically compatible with the FELONY’s IC5 main power connection, although this conventional EC5 battery does not provide Spektrum Smart battery data.
A fully charged pair reaches 26.1V when charged to 4.35V per cell. Confirm that the installed ESC supports the selected maximum voltage before using the batteries in full LiHV mode.
12S 110mm EDF Battery Setup
Four matched 3S packs can be connected in series to form a 45.6V nominal 12S 9000mAh LiHV system for large, high-current EDF aircraft.
In a composite F-16 equipped with a 110mm Schübeler EDF and TP 5690 motor, this four-pack configuration produced 11.2kg of measured thrust. The batteries measured approximately 109°F, or 43°C, after a five-minute test run.
The result demonstrates strong voltage delivery under a demanding EDF load. Thrust still depends on the complete fan, motor, ESC, intake, exhaust, wiring and test conditions rather than the battery alone.
Four packs weigh approximately 1,992g and reach up to 52.2V when fully charged in LiHV mode. This configuration is intended for aircraft with adequate battery space, structural capacity, cooling and a correctly rated 12S power system.
Compatible RC Applications
ARRMA FELONY 6S
Use two matched 3S packs in series for a high-capacity 6S street setup. Confirm tray retention, total battery weight and ESC voltage compatibility.
ARRMA INFRACTION and Similar 1/7 Street Cars
The battery is suitable for compatible dual-3S street platforms where each tray accepts the 139 × 47 × 37mm case and approximately 498g pack weight.
Large 3S RC Cars and Trucks
One pack can power large 3S vehicles that have sufficient battery space and can benefit from the 9000mAh capacity and strong current reserve.
Custom 6S Surface Builds
Two matched batteries can be used in speed-run, street-bashing and large-scale custom systems designed for the resulting voltage, weight and available current.
Large 12S EDF Jets
Four matched packs can support appropriately designed 12S EDF installations where battery space, center of gravity, cooling and total aircraft weight have been confirmed.
High-Power Electric Aircraft
The pack can also be used in custom electric aircraft systems that accept its dimensions, weight, EC5 connection and LiHV voltage.
EC5 and IC5 Connector Compatibility
EC5 and IC5 are physically compatible at the main power interface. This battery can connect to a corresponding IC5 device connector and provide normal positive and negative main power.
This is not a Spektrum Smart battery. It does not provide automatic battery identification, Smart charging settings or battery telemetry through the additional IC5 data contact.

FAQ
Does this battery fit the ARRMA FELONY 6S?
Yes. Use two matched 3S packs in series to create a 6S 9000mAh setup. Confirm battery retention, total installed weight and ESC support for the selected LiHV charge voltage.
How many packs are required for a 6S setup?
Two matched 3S batteries connected in series produce a 6S system.
Do two 9000mAh packs become 18000mAh?
No. Two packs connected in series remain a 9000mAh system. The voltage doubles, but the capacity does not.
Can four packs be used in a 12S EDF jet?
Yes. Four matched packs can form a 12S 9000mAh system for a correctly designed large EDF installation. The aircraft must support the approximately 1,992g battery weight and up to 52.2V fully charged voltage.
Is EC5 compatible with IC5?
Yes. EC5 and IC5 are physically compatible for the main power connection. This battery does not provide Spektrum Smart battery data.
What charger is required?
Use a balance charger that supports 3S LiHV batteries. Select the LiHV program and do not exceed 4.35V per cell.
Should the battery always be charged at 5C?
No. The 5C value is the maximum specified charge rate, not the required everyday rate. A lower balanced charge rate generally creates less heat and cell stress.
Notice
- This is a 3S LiHV battery with a maximum charge voltage of 4.35V per cell.
- Use a compatible LiHV balance charger and select the correct cell count before charging.
- Confirm the battery dimensions, weight, connector and maximum ESC input voltage before use.
- EC5 and IC5 are physically compatible for main power, but this battery does not provide Spektrum Smart data.
- Only connect matched batteries of the same model, condition and charge level in series.
- Secure every battery firmly and keep the main and balance wires away from moving parts.
- Never charge unattended, and do not use a swollen, damaged or overheated battery.
- Allow the battery to cool before recharging and use storage mode when it will not be used for an extended period.
