Arduino battery charger4/3/2023 What I know for sure is that I want the batteries to be permanently attached to my robot and have the charging circuitry on the robot too. But right now I’m feeling totally overwhelmed by all the options for batteries, the S and C ratings (Both charging and discharging) etc. I would like 7.4v and as many mAh as I can get. But if you have a suggestion for a battery from literally anywhere, please share! I’m sure I can find a supplier here! I have to order the batteries from in South Africa because there are laws about importing batteries and basically nowhere online will ship batteries here because you need a special license to do it. This is the 7.4v LiPo which I had my eye on if I can’t get the 18650s to work out: Would it still work? Would I just leave the JST connector unplugged? That seems to be for 7.4v LiPos which as I understand are made from two cells, but it doesn’t seem to have anywhere to plug in the JST plug for balancing which the 2 cell LiPos all seem to have. The other charging module I could get it this: 1PCS-Micro-USB-5V-1A-18650-Lithium-Battery-Charger-Module-Charging-Board-With-Protection.jpg 597×559 59.9 KBīut from what I’ve read that won’t work because the voltage is too low and if I use two batteries then I have to use a balancing circuit.
