I have just had 860 Amp/hr at C20 of 2v tractions(12v) fitted by PB batteries with an autofill system and gasing sytem, excellant fitting service all in price £1257.00.
I use on average 100-110 amps a day and have put these to the test. I have not run my engine since Sunday Last week until this morning, have used in excess of 600 amps, voltage down to 12.15v and SG 1.18 per cell.
How much further could I take these down, I know I can take them down to 20% , but what voltage and SG would I be looking for?
