hey guys, i have an idea to make a diy 3d printed drill, i use a 12v dc motor and three 1865 li-oh batteries in series to get power.
my question is, can i connect the batteries in parallel at the same time and charge them with a battery charge module without a it getting short?
btw, the battery pack is just two batteries in the bottom and one on top (like a piramide) i just soldered them in series.
