to be honest, i’m not sure why i stock these…..you can buy the whole kit with all you need for a 2nd battery from me….which is the sensible thing to do if you want a 2nd battery….i just thought these might be useful…so there you go…..your homework is find a good use for these that is UA related and doesn’t involve a battery. (is handy though if you do want to fit a 2nd battery and have all the other bits, kinda like the key to the door, the holy grail, the last hobnob in the barrel….. the greatest thing in the world if you’re looking for it kind of thing) anyway… i have some..
