How to Choose a Battery for Your AEG
An AEG battery must match the replica, electronic control and available battery space. Do not choose by voltage or capacity alone. Check the replica or ETU manufacturer’s documented limits before connecting a different battery.
Five checks before ordering
- Chemistry: use the charger and storage method intended for that battery type.
- Voltage: remain within the documented limit of the AEG and electronics.
- Connector and polarity: confirm both before connection; never force a plug.
- Physical size: measure the compartment, cable path and connector clearance.
- Capacity and discharge rating: treat these as part of a complete electrical system, not as a standalone performance guarantee.
LiPo handling
Use a compatible balance charger, monitor charging, and store the battery according to its manufacturer’s instructions. Stop using a pack that is swollen, damaged, unusually hot or has damaged wiring. Transport and disposal must follow local battery rules.
Match the build
Motor, spring, gear configuration, wiring and electronic control affect electrical demand. A DSG or other specialist build should not inherit a generic battery recommendation from another replica. Document the actual components, then select within their limits.
