This is as simple as it gets. This charger charges a 2s or 3s lipo at 2.1a of charge current (700ma to each cell at the same time). It uses the Lipo's tap port to charge.
It requires the JST XH style tap (also called Align). If you do not know which tap you have on your current lipo let me know. All Elite lipos use the Align connector. If you purchase a Thunder Power battery from us then you will need the TP->AL 2s or 3s adapter.

Functions/Instructions
You will see there are 3 lights on this unit. One for each cell your lipo has. Plug the charger in first with NO LIPO ATTACHED. The lights for cell 1,2 and 3 will turn red indicating they are charging the cells. When each light turns green the charge is complete. Since the charger charges each cell individually it does balance the pack.
