SKYRC LiPoPal is a simply used battery checker and self voltage balancer. When we are flying or running outside, it is difficult to know the remaining capacity of the battery. With this tiny LiPoPal we could check the voltage of each cell and the remaining capacity in percentage at anytime and anywhere. As we know, if each cell of the battery pack is balanced, the battery performance will be much better and the cycle life will be longer. But sometimes, we may don’t have time or tool to balance the battery cell. With this small kit, when it detects the pack is not balanced, it will start work to balance the pack cell at once.
