Smart Battery Innovation
When linked to a Spektrum™ Smart charger, a Smart battery's unique parameters, health, and stabilizing information upload automatically from its memory microchip through the IC3® or IC5® connector's data wire. To charge and stabilize the pack, you merely link it to your Smart charger. Safe charging begins automatically. Smart Automobile storage discharge makes sure a longer battery life.
 

Smart Automobile Storage Discharge
Spektrum™ Smart G2 batteries practically look after themselves. G2 batteries originate from the factory set to automatically release to a safe storage voltage of 3.90V after 72 hours of inactivity. The outcomes are longer battery life, better efficiency 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 passed on from your Spektrum™ Smart battery to your Smart charger, making charging as basic as plugging in the pack. The battery's incorporated microchip remembers the last charging rate you set, so the next time you plug it in, these settings will automatically take effect.
