Compact 2S2P Hardcase Battery for Racing
The CNHL Racing Series 4900mAh battery uses a 2S2P cell configuration. Two cell groups are connected in series to produce 7.4V nominal voltage, while parallel cells within each group provide the combined 4900mAh capacity and support strong current delivery.
The compact 96mm case makes this pack different from a conventional full-length 2S battery. Its shorter footprint allows the battery position to be adjusted more easily in compatible trays, helping racers tune front-to-rear weight distribution rather than allowing the battery case to fill the complete tray.
The rigid outer case helps protect the cells from track debris, chassis contact and routine racing impacts. It remains important to secure the pack correctly and prevent the case, wires or connector from rubbing against rotating or sharp components.
Why Choose This Battery?
Near-5000mAh capacity without a full-length case
The 4900mAh capacity stays close to the common 5000mAh racing class while using a much shorter 96mm case. This provides useful runtime for practice, club racing and longer mains without automatically adding the size of a conventional full-length pack.
Lower weight for responsive 2WD handling
A lighter battery can reduce overall vehicle mass and help a 2WD oval or buggy chassis change direction more easily. The result can be a more responsive feel during corner entry, rotation and acceleration away from the apex.
More freedom to tune chassis balance
Because the battery is shorter than a standard stick pack, it can be positioned farther forward or rearward in a compatible adjustable tray. Moving the battery forward generally adds front-end stability and steering load, while moving it rearward can increase rear traction and rotation. The ideal position depends on the track, tires and suspension setup.
120C discharge capability
The 120C continuous and 240C burst ratings, EC5 connector and 10AWG wires are designed for high-current 2S racing systems. Actual performance remains dependent on the ESC, motor timing, gearing, tire load, track grip and operating temperature.
A Best-Overall Battery for the Losi 22S Dirt Late Model
The CNHL Racing Series 4900mAh 2S 120C hardcase LiPo battery is a strong all-around option for the Losi 22S Dirt Late Model. Its capacity remains close to the 5000mAh class commonly used for track driving, while the compact case and lower weight support responsive 2WD oval handling.
The 22S Dirt Late Model uses an adjustable battery tray that can secure either full-length or short battery formats. The 96mm CNHL case allows the tray stops to be adjusted around the battery and gives the driver room to tune its fore-and-aft position.
The battery's EC5 plug is physically compatible with the vehicle's stock IC5 main power connector, so no adapter is required when the original IC5 connection remains installed. This is a conventional EC5 battery and does not provide Spektrum Smart battery data.

Battery Position and Dirt Oval Handling
A compact battery gives racers an additional setup tool. The battery position can affect how quickly the chassis rotates, how much front steering it develops and how securely the rear tires remain loaded under acceleration.
-
Battery farther forward: Can add front-end stability and make the car feel calmer during corner entry.
-
Battery farther rearward: Can increase rear traction and help the chassis rotate, but too much rearward bias may reduce steering consistency.
-
Battery centered: Provides a neutral starting point for drivers who are still developing their suspension and tire setup.
Always keep the battery fully supported and securely retained. Do not position it where the case, balance lead or main wires can contact the driveshaft, spur gear, motor or suspension components.
Compatible RC Models and Applications
1/10 Dirt Oval Cars
The compact format is well suited to dirt late models, sprint cars and other 2S oval platforms with adjustable shorty-compatible battery trays. The combination of near-5000mAh capacity and lower installed mass supports a balance of runtime and responsive handling.
2WD and 4WD Racing Buggies
This battery can be used in buggies that accept its 96 × 46.5 × 25mm case and side-exit wires. Check tray stops, foam spacers, strap position, connector clearance and class rules before racing.
RC Sprint Cars
The short case provides room for fore-and-aft battery placement in compatible sprint-car chassis. This can help drivers tune steering response and rear traction for different surfaces.
2S Touring, Drag and Custom Racing Cars
The pack may also suit other compact 2S race vehicles when the dimensions, weight, EC5 connection and battery-retention system match. Confirm whether the vehicle or racing class requires a specific case length, connector orientation or ROAR-approved battery.
EC5 and IC5 Physical Compatibility
EC5 and IC5 are physically compatible at the main power connection. This battery's EC5 plug can connect to a corresponding IC5 device connector when the orientation and polarity are correct.
This is not a Spektrum Smart battery. It provides normal positive and negative main power but does not contain the Smart electronics or data connection used for automatic battery identification and battery telemetry.
When used with an IC5-equipped vehicle such as the Losi 22S Dirt Late Model, normal power can be supplied without an adapter, but Smart battery information will not be available. Charger settings may need to be selected manually.
4900mAh Short Pack vs. a Larger Full-Length Battery
| Battery Direction |
Main Advantage |
Main Tradeoff |
| 4900mAh compact hardcase |
