Hi I would like to make something which can be charged Without taking the batteries out of the robot. I am thinking of using nimh batteries as I have heard that lipos are crazy and hard to do. I have read bait about this but all I have heard how powerfully to charge them and things to d with trickle charging and making sure u don't over charge the batteries but I don't anything about the very basics, like I have absoloutly no idea what I'm doing How can I charge the batteries whilst they are in the robot with out applying all the power to the robot? In most things the batteries go alternate ways but in charging I've seen the all the same way And just the general basics like actually getting the batteries to charge (hooking them up the right way e.t.c.) Thanks for any thing you can sayall help would be appreciated.
