November 15, 20178 yr anybody played around with lipo batteries , I am wanting to make a low tech pet project , a small battery back up that can be charged using grid (maybe old laptop charger)and or solar. something like a powerbank but with 12v as well. I can get 18650 bats from china town fair cheap .Yes I know I could make it from 7ah gate motor type bats but. I want to put in a usb port, 12v output to run some led lights ( whos voltage seem to be quite flexible) solar panel(s) charging port .voltmeter I've seen a couple of vids on you tube but the charging voltages are obviously different and 12v seems just awkward but 24v fits into a more flexible area esp since I have a 24v controller and I have a 24v to 12v converter. I can also get a lighter type usb car charger that works on 24 or 12v , so that has a lot of flex looking forward to comments and ideas cheers
