Best 7.4V 2S LiPo Battery Upgrade Options
The included 7.4V 600mAh Li-ion pack is fine for casual use. For stronger torque response and more consistent output, consider upgrading to a high-discharge 2S LiPo rc battery:
Connector note: Check your unit’s battery connector before upgrading. Some batches may use JST, others XT30. Match the plug (or use an adapter) and always confirm polarity and battery bay size prior to installation.
