Just at the stage of selecting batteries for my rov
I know lipos would probley be best But worried about the risks of lipos and the problems with over discharging.
So would like suggestions for alternatives I will be running 3 brushless 800kv outrunner motors. Rated at between 7A and 9A.
Plus an arduino and a camera and a couple of servos.
The battery or batteries should supply 12V for as long as possable and if possable fit in a round tube that is 98mm D by 300mm long.
This is my first project so a bit lost
Thank you in advance
