This battery REQUIRES the 'Onyx RCR XR Extended Battery Cover' and WILL NOT fit with the stock battery lid. This battery will connect directly to the stock controller if you select the Anderson SB50 connector, however, we suggest upgrading the Anderson SB50 terminals on your controller to QS8 for better power delivery and better heat resistance.
