The SkyRC e3 is a compact and affordable Lithium-Polymer battery charger that can easily charge and balance 2S and 3S LiPo batteries directly through the balancer connector. This charger is intended to be connected directly to the AC mains (110-240V compatible). The SkyRC e3 balances and charges LiPo batteries with 800mAh current, so it can take a while for large capacity batteries to be fully charged. The best thing about it is that it is very compact in size and at a great price, so good for a start-up charger/balancer with your first RC car or as a second backup charger.
