I had to buy new BRCA legal batteries this season and leave my pefectly good 2 year old 4200's at home. After 4 months use (5 National meetings!) all my 2008 cells have had cells go down despite equalizing every use. They are easily the worst batteries I've ever bought
.
I'm keen to see Lipo's in off-road as I'm fed up with the lottery of NiMh buying, plus no more assembly and the other outdated crap NiMh's require.
I don't know all the Lipo risks hinted at on this thread. Why can't someone list them? I understand they can catch fire if damaged or charged incorrectly, but as somebody has already stated, I'd rather face the risk of a fire than exploding NiMh shrapnel inside a tent at point blank range.
