Hi ALL, need help, I have here a portable oscilloscope, its new old stock. it works a treat but the batteries are not to good as they're passed their sell by date. What I would like to do is add 18650's and a charging /bms board, Im not to worried about removing the old batteries or using the units charging / bms, if I can it'll be a major bonus but there is room for extra charging / bms and socket. what I really need is that it charges from a 12 volt supply.
here's is what is what is already fitted, whats the best way to to got about this
Thanks
