Buying Guide

Choose the right chemistry

NiMH is forgiving and compatible with many stock guns and smart chargers, while Li-ion/LiPo offer higher energy density and discharge but require compatible gear and careful charging

Match voltage to your gearbox

Common voltages include 8.4V for traditional NiMH packs and 11.1V for 3S Li-ion/LiPo setups; use the voltage your AEG or gearbox supports to avoid excess wear or performance issues

Consider capacity (mAh) for runtime

Higher mAh ratings like 1600–3000mAh extend playtime between charges but may add weight and size, so balance runtime with your gun's battery compartment and handling

Check connector type

Match the pack's connector (Mini Tamiya, T-Plug/Deans, etc.) to your gun or be prepared to rewire/adapt; correct connectors ensure reliable current flow and safer connections

Use appropriate chargers

Smart chargers for NiMH packs and balance chargers for LiPo/Li-ion are important for safe charging, battery health, and preventing overcharge or imbalance
