I have been using lipo's for many years now. One of the best practices for maximizing cycle life and safety is to balance the cells when you charge the battery. Does anyone know if the battery has a built in balancer? Also I have a way better charger that has active cooling. Has anyone used another charger to charge the solo batteries? Has anyone used a generic four cell lipo to power their solo? I'm thinking that I am going to want 4 batteries dedicated the solo and I want to charge them all at the same time with my 4 way balancing charger.
