I have an Omars 40200mAh battery pack with an AC adapter and I am wondering if it’s possible to use the F Stop Labs 5-in-1 battery charger to charge my M2Z batteries. I have tried it and it seems to work with one battery plugged in, but when I plug a second battery in, the Omars battery pack turns off. I don’t know much about electricity or the like, so was hoping someone can offer up any advice. Thanks!
