yeah, the esky charge is almost exactly the same as the eflite balance charger. It just has a couple of differences, like bigger internal diodes, a relay to connect or disconnect the pack, and it doesn't have the aligator leads perminantly attached, instead the hook on the DC power plug so you can only have one hooked up at a time which makes it so you can't break it as easy. Also mine comes with a 2s and a 3s balance port, and also charges at 800mA
