Hi Jim

I have found the easiest place to pick up a leisure battery is a caravan accessory shop. You can get them in Halfords, but seem a bit pricier, and there are loads of them on line with free delivery which is pretty good as they are quite heavy!!

Basically just need to make sure they are a deep cycle leisure battery and not a normal 12v car battery. My current leisure battery is a 80AH one and this has lasted for all day buggy events with both my and my sons lipos being charged off it. I think it was about £65 bought locally. Unless you are going to lots of 2 day outdoor race meetings where you will not get the chance to charge it overnight then I cannot see much point in a larger capacity one unless it is a really good price – just more expensive and bigger/heavier to carry. I suppose you could justify it on the basis that as the battery gets a bit older and loses some of its capacity, then a larger capacity one might carry on a bit longer??

You will need to get a charger which is designed for leisure/marine batteries and not one for normal 12v car batteries. Leisure batteries and 12V car batteries look very similar to me but understand that their charge/discharge characteristics mean they cannot be treated the same.
