Core Description
The CNHL Racing Series 6600mAh 2S 120C hardcase LiPo battery is designed for RC users who want longer sessions without giving up strong throttle response. Compared with common 5000mAh or 6200mAh 2S packs, this 6600mAh battery adds extra runtime while still keeping the pack in a practical full-length stick-pack format for many 1/10 RC vehicles.
The 120C discharge rating gives this battery a more aggressive performance profile than ordinary 2S packs. It is useful in applications where the battery needs to respond cleanly during acceleration, drift transitions, crawling load changes, corner exit, or repeated stop-and-go driving.
The hardcase shell helps protect the cells in surface RC use, where battery trays, straps, chassis vibration, and repeated installation can put more stress on a pack. For crawlers, touring cars, drift builds, vintage chassis, and 1/10 bashers, that extra protection is one of the main reasons to choose a hardcase battery.
High-Capacity 2S LiPo Battery for 1/10 RC Cars, Crawlers, and Vintage Platforms
The CNHL Racing Series 6600mAh 7.4V 2S 120C Hard Case LiPo Battery with T/Dean Plug is built for 1/10 RC vehicles that need long runtime, reliable punch, and stable voltage delivery. It is a strong choice for RC crawlers such as the Traxxas TRX-4, Axial SCX10 II / III, Redcat Gen8, and Element Enduro, where torque response and endurance matter on technical trails.
Beyond scale crawling, this 6600mAh pack can also work well in short course trucks, bashers, stadium trucks, vintage race chassis, and general 2S platforms such as Slash, Rustler, Bandit, E-Maxx, Losi, Team Associated, Kyosho, and Tamiya builds when tray length, plug angle, and connector setup are suitable.
The T/Dean plug is practical for many older and race-oriented RC setups. If your model uses another connector, browse our RC battery adapters collection and choose a properly rated adapter for XT60, TRX, EC3, EC5, IC3, IC5, or Tamiya-style systems.
Traxxas 4-Tec 2.0 Nissan 240SX Brushless 2S Setup
The CNHL Racing Series 6600mAh 7.4V 2S 120C Hard Case LiPo Battery with T/Dean Plug is a practical 2S option for the Traxxas 4-Tec 2.0 Nissan 240SX Brushless. A 2S LiPo keeps the 4 tec 2.0 easier to control in smaller parking lots, tight road-course layouts, and casual street driving, while the 6600mAh capacity supports longer driving sessions.
This setup is especially useful for drivers who want smoother throttle response instead of maximum 3S speed. On a low AWD street chassis like the Traxxas 4tec Nissan 240SX, 2S power can be easier on tires, easier to manage through corners, and more comfortable for everyday use.
Important plug note: this battery uses a T/Dean plug. The Traxxas 4-Tec 2.0 Nissan 240SX Brushless uses a Traxxas High-Current connector, so this battery does not plug directly into the car. To use it, you need a T/Dean-to-TRX battery plug adapter or a proper connector conversion. Always confirm adapter rating, polarity, and wire clearance before running.

Fitment Notes for RC10 1989 Stealth Car and Tamiya DB01 / DB01SR
This battery is also a clean option for vintage-style and classic race platforms like the Team Associated RC10 ’89 Stealth Car, where a full-length 2S stick-pack hardcase format can match the traditional battery layout. Additional options for classic race chassis can be found in our dedicated guide: RC10 1989 Stealth Car LiPo Collection.
For modern belt-drive buggies such as the Tamiya DB01 Durga and DB01SR, this full-length stick-pack format may also match the original tray direction, but wiring and connector clearance need to be checked carefully. More detailed fitment information is available here: LiPo Batteries for Tamiya DB01 & DB01SR.
Compatible 2S LiPo Upgrade for Kyosho Fazer D2 Drift Builds
For the Kyosho Fazer D2 (FZD2) RWD drift chassis, this 6600mAh 2S pack brings long practice time and smooth power delivery, which helps maintain predictable throttle control during transitions and extended drift sessions. The added capacity is useful for drivers who want fewer battery swaps while practicing throttle timing, line control, and long drift sequences.
Explore more drift-focused options in our Kyosho Fazer D2 Drift Car Battery Collection.
Racing Series 120C and LiHV Alternatives
Some users may be searching for the CNHL Purple Series through third-party platforms. For stronger discharge performance and better race-oriented output, we recommend choosing the Racing Series 120C or stepping up to the high-voltage Racing Series LiHV hardcase lineup for top-tier performance builds.

Is 6600mAh better than 5000mAh?
It depends on the model. A 6600mAh battery usually gives longer runtime than a 5000mAh pack, but it is also heavier. It is a good choice when longer driving sessions matter more than minimum battery weight.
Notice
- Only use a compatible LiPo balance charger designed for 2S LiPo batteries.
- Stop charging immediately if any cell exceeds 4.2V.
- Check voltage, connector type, adapter rating, battery tray size, wire clearance, and battery retention before purchase.
- Inspect the battery surface, connector, wires, balance lead, and cell voltage before first use.
- Do not use the battery if it becomes swollen, damaged, overheated, or physically deformed.
- For adapter use, confirm polarity and current rating before connecting to the ESC.
- For long-term storage, store the battery at proper storage voltage in a cool and dry place.
- If a new battery does not initially hold full performance, several normal balanced charge and discharge cycles may help stabilize the cells.
- Always follow standard LiPo safety procedures during charging, storage, transport, and use.
