Gens ace iMars D300 Plus G-Tech Dual-Channel AC/DC Charger 300W/700W

The Gens ace iMars D300 Plus is a two-channel smart balance charger that runs from mains or a DC supply and charges two 1–6S lithium packs at once, at up to 16 A per channel. Connect a Gens ace G-Tech smart battery and it reads the battery type, voltage and recommended charge current through the smart balance plug; ordinary packs are set up manually.

On mains the two channels share 300 W, roughly 6 A each when charging two 6S packs together, so run it from a DC power supply when you need full speed on large packs. The mains cord has an EU plug; keep an adapter handy for Indian sockets.
