Smart Battery Technology

When connected to a Spektrum Smart charger, a Smart battery's unique parameters, health, and balancing information upload automatically from its memory microchip through the IC3® or IC5® connector's data wire. To charge and balance the pack, you simply connect it to your Smart charger. Safe charging begins automatically. Smart Auto storage discharge ensures a longer battery life.

Smart Auto Storage Discharge

Spektrum Smart G2 batteries practically take care of themselves. G2 batteries come from the factory programmed to automatically discharge to a safe storage voltage of 3.90V after 72 hours of inactivity. The results are longer battery life, better performance over the life of the pack and peace of mind that your Smart battery comes maintenance-free.

Simple and Quick

Preset charge, discharge, and storage parameters are automatically relayed from your Spektrum Smart battery to your Smart charger, making charging as simple as plugging in the pack. The battery's integrated microchip remembers the last charging rate you set, so the next time you plug it in, these settings will automatically take effect.
