6600mAh Capacity in a 24mm Hardcase
The 6600mAh capacity gives this pack more stored energy than lower-capacity 2S batteries, while the 24mm hardcase height keeps the profile relatively low for a full-length stick-pack format.
That combination is useful for touring, drift, crawler and vintage-style chassis where drivers want more energy reserve without moving to a much thicker battery.
Why Choose This Battery?
-
6600mAh capacity: Large energy reserve for longer RC sessions.
-
120C continuous rating: Designed for demanding 2S brushless systems.
-
24mm hardcase height: Relatively low profile for a full-length 6600mAh pack.
-
Hardcase protection: Useful for surface RC chassis and repeated battery installation.
-
T/Dean plug: Suitable for many traditional race, drift and vintage RC installations.
-
Standard 2S LiPo chemistry: Charges to 8.4V and does not require LiHV mode.
6600mAh 2S Battery for CEN Racing Matrix
The CNHL Racing Series 6600mAh 2S 120C hardcase is a capacity-focused option for compatible CEN Matrix-E Buggy and Matrix Stadium Truck setups where a full-length 2S pack and T/Dean connection suit the chassis.
Its 6600mAh capacity is particularly relevant to drivers who prioritize more stored energy and fewer battery changes during practice or extended driving. Compare additional options in the CEN Racing Matrix Battery Collection.
2S Battery Option for Traxxas 4-Tec 2.0 Nissan 240SX
This 6600mAh hardcase can also be considered for the Traxxas 4-Tec 2.0 Nissan 240SX Brushless as a 2S option when the battery tray accepts the pack. The lower 2S voltage offers a different driving character from a 3S setup and can be useful for street and tighter-layout driving.
This battery uses T/Dean rather than a Traxxas connector, so a properly rated adapter or connector conversion is required. See more options in the Traxxas 4-Tec 2.0 Nissan 240SX Battery Collection.
2S Battery for Kyosho Fazer D2 Drift Builds
The full-length 6600mAh format is also relevant to compatible Kyosho Fazer D2 / FZD2 drift setups where additional capacity is preferred for longer practice sessions.
Confirm tray dimensions and connector routing before use, or browse the Kyosho Fazer D2 Drift Car Battery Collection.
RC10 ’89 Stealth Car and Tamiya DB01 / DB01SR
The traditional full-length hardcase format can also suit compatible Team Associated RC10 ’89 Stealth Car and Tamiya DB01 / DB01SR layouts when battery dimensions and wiring clearance match the chassis.
See the RC10 ’89 Stealth Car Battery Collection and Tamiya DB01 / DB01SR Battery Collection.
Crawler, Touring and General 2S Applications
This battery may also suit compatible RC crawler, touring, short-course and basher platforms where the 139 × 47 × 24mm dimensions, approximately 317g weight and connector arrangement fit correctly.
Vehicle name alone does not confirm compatibility; always check the actual battery tray, hold-down system, wire exit and ESC connector.
T/Dean Connector and Adapter Use
This battery uses a T/Dean output connector. It connects directly only to the corresponding T/Dean device-side connector with correct polarity.
For TRX, XT60, EC3, IC3, EC5, IC5 or other connector systems, use a properly rated adapter or professional connector conversion. Browse compatible options in the RC Battery Adapter Collection.
Standard 2S LiPo Charging
This is a standard 2S LiPo battery. Maximum balanced charge voltage is 4.20V per cell, or 8.40V total.
Do not charge this battery using a 4.35V-per-cell LiHV mode.
For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target.

FAQ
Is this battery suitable for CEN Racing Matrix?
It is a capacity-focused 2S hardcase option for compatible Matrix-E Buggy and Matrix Stadium Truck setups when the tray dimensions and T/Dean connection suit the vehicle.
Is this battery a standard LiPo or LiHV?
This is a standard 7.4V 2S LiPo battery with a maximum balanced charge voltage of 8.4V.
Is 6600mAh better than 5000mAh?
6600mAh provides more stored energy, but it may also increase battery weight. The better choice depends on tray fitment, desired runtime, chassis balance and driving style.
Can this battery work with Traxxas connectors?
Not directly. This battery uses T/Dean, so a properly rated T/Dean-to-TRX adapter or connector conversion is required.
Can this battery be used in RC crawlers?
It may suit selected crawlers when the 139 × 47 × 24mm battery dimensions, approximately 317g weight and connector setup fit the vehicle.
Does 120C mean the vehicle always draws extremely high current?
No. 120C is the battery's stated continuous discharge rating. Actual current depends on the motor, ESC, gearing, vehicle load, traction and driving conditions.
Should this battery always be charged at 5C?
No. For routine charging, a balanced 1C rate is preferred. 5C is the stated maximum, not the everyday target.
Notice
- This is a standard 2S LiPo battery with a maximum charge voltage of 4.20V per cell.
- Do not charge this battery using LiHV mode.
- Confirm the 139 × 47 × 24mm dimensions, approximately 317g weight and T/Dean connector before use.
- Voltage and connector alone do not establish compatibility; battery dimensions, weight, retention and wiring clearance must also match.
- If using an adapter, confirm connector polarity and current rating before connecting the battery.
- Secure the pack firmly and keep power and balance wires clear of gears, driveshafts, suspension components and sharp chassis edges.
- Never charge unattended, and do not use a swollen, punctured, damaged or overheated battery.
- Allow the pack to cool before recharging and use storage mode when it will not be used for an extended period.
