Probably a 6s is the absolute lowest voltage you want, but most people do 8s or above. With 6s don’t expect much power wise.
In that case, placing a car battery wouldn’t work then (?). I might be considering to build a custom battery pack, hell I want to build one as it is cheaper for me to access those cells, will it be tough to build one?
Most car batteries have high amps, low volts I believe. Plus the chemistry of the battery is off so there won’t be as much support on the forum for that. A lot of people build there own custom battery, and if you have the materials (spot welder, nickel strips, cells) then that is a great solution.
Those stuff are easy to get here, and at a really great price. Probably will learn how to build one, and lay off my board for the next few weeks or so
Bump this chat a lil’ I managed to get my hands on some LG 18650 S3 2200mAh (Blue) batteries recycled off some laptop batteries, is it good ? @barajabali
What batt’s would you recommend then, ones that are bang for buck, and where to get em?
Best value are the Samsung 25Rs.
