The ACM 7.4V 550mAh 20C Li-Po Battery is a high-performance power solution specifically designed for Automatic Electric Pistols (AEPs). Featuring a compact form factor and a Mini Deans (T-Connect) plug, it provides a significant upgrade over standard NiMH packs, offering improved trigger response and a consistent rate of fire for MOSFET-equipped sidearms.
ACM 7.4V 550mAh 20C Li-Po Battery – Mini Deans Edition
Upgrade your airsoft sidearm with the ACM 7.4V 550mAh Li-Po Battery. Engineered for the tight constraints of electric pistol frames, this 2-cell Lithium-Polymer battery is the go-to choice for players looking to enhance the performance of their MOSFET-equipped AEPs, such as the CYMA Gen 3 series and other compact electric platforms.
Optimised for Performance
Unlike traditional NiMH batteries, this Li-Po cell maintains a stable voltage output throughout its cycle. The 20C discharge rating ensures your motor receives the power it needs for a snappier trigger response and a more reliable cycle rate. Its lightweight, slimline construction allows it to slip easily into the limited battery space located under the slide of most modern airsoft pistols.
- High Compatibility: Specifically designed for AEPs with Micro Deans/Mini Deans wiring.
- Compact Dimensions: Slim profile (approx. 70mm x 17mm x 12mm) ensures a perfect fit in compact battery compartments.
- Mini Deans Connector: Fitted with a low-resistance Mini Deans plug for superior electrical conductivity.
- Li-Po Technology: Offers a higher energy density and faster discharge compared to standard rechargeable cells.
Safety & Charging
This battery features a standard JST-XH 3-pin balance lead. It must be charged using a dedicated Li-Po balance charger to ensure the longevity and safety of the cells. We highly recommend using a Li-Po safety charging bag during the charging process.
Technical Note: Please ensure your airsoft pistol is compatible with 7.4V Li-Po batteries before use. Using Li-Po batteries in non-MOSFET AEPs may lead to premature wear of the trigger contacts.
