Total capacity being equal, one big 12V is the same as two 6V, and both are better than two 12V. So it is down to price, maximum weight of battery you can cope with, and dimensions to fit.
12v deep cycle batteries with a good peukerts number will give you a good output in terms of A/h and are obtainable far and wide. Not so sure the equivelant is available in 6v. You might only be able to get motorcycle batteries which are designed for high current/ low time useage and will mean you will only get a fraction of the quoted A/h rate.gazracer said:My leisure battery has finally given up the ghost after 7 years, which I think is pretty good. Anyway..
We're off to france for 2 weeks wild camping at the end of the month, so, shoud I replace with 1 big 12v or switch to 2 x 6v ???
Cost is not a major issue, but certainly a consideration.
Your opinions are welcome and if you can point me in the direction of cheap suppliers all the better! :lol:
To compare you need the manufacturers quoted peukerts number to compare like with like. A 120 A/h battery with Pn = 1.08 will give you 101 min if drawing 50A but a 120A/h battery with a Pn = 1.5 will only give you 20 mins drawing 50A.gazracer said:I was reading an article somewhere, maybe by a selfbuilder, who had sourced golf cart batteries as they are designed to do the same as leisure batteries?
