thanks guys
roger mate you will be fine most of us dont have any trouble as glypo has said when im racing touring which ive now started doing mod the cells only have 400 mah left in them and i get them repeaked in time i do have a cooling fan to cool them but to be honest they may not be cold when i recharge but i have been running 4200 all season with no trouble at all they dont even get above 35 degrees.
happy days if you worried i think ive got some old 2000mah nicads i used to charge straight from a twelve volt years ago you can borrows those they wont go bang LOL
