Spektrum 7.4V 2200mAh 2S 30C Smart G2 LiPo Battery – IC2 SmartFit Case (ARRMA GROM)
Get more run time from your ARRMA GROM lineup with the Spektrum 7.4V 2200mAh 2S 30C Smart G2 LiPo Battery in the SmartFit case. Custom-designed in size, shape, and 30C rating specifically for the ARRMA GROM 1/14 to 1/18 scale mini RC lineup, this 2200mAh pack delivers 57% more capacity than the 1400mAh standard pack for noticeably longer sessions between charges — while still fitting correctly in the GROM's battery compartment thanks to the SmartFit case design. Smart G2 technology makes charging as simple as plugging in — the integrated microchip automatically uploads all parameters and health data to your Spektrum Smart charger, and Auto Charge begins immediately without any manual settings required. Smart Discharge automatically brings the pack to your predetermined storage voltage after 12 to 240 hours of rest, protecting cell chemistry and extending overall pack life without any manual intervention. The 30C continuous discharge rating and 5C maximum charge rate deliver the performance and longevity that demanding GROM drivers need.
