I am a part of my school's drone club and we recently purchased 4 gremlins. I realized today that we might not have a way to charge the batteries. We are using 450mAh 2s 50c batteries, but all we have in terms of chargers are two of the X4 Micro 1s Lipo Chargers. I assume that because the X4 is designed for 1s batteries, charging the 2s gremlin batteries with them will cause problems. Is that correct? If so, does anyone have a recommendation for a multi-port charger that can charge multiple gremlin batteries at the same time? We have 16 of them so we obviously don't want to charge them one at a time.
