Hi

my battered old Turf2 has dead batteries. I have a 3 acre site, with some hills to it. I dont need massive range capacity, probably up and down say 4 times a day, tops. Im going to use much much smaller batteries than normal - 40Ah or 80Ah.

I have the oppertunity to use some 'odd' batteries, 12v 7ah jobbies. im going to make up a big bank of them. im paying £1.50 each.

So - all the cables have to be terminated at a busbar - what size busbar should i go for? Im guessing a 250a would be nice.

250a to 300a based on your loading.
