www.stormforceracing.co.uk neils IB 4200 are top notch he matches his competition cells to a threshold of 20mah.Larger companys match theres to 35msh. I use his GP4300 that he used to sell and they are matched to a high level and you get a free discharge chart to show you how well our cells are matched. Top notch cells, top notch chap, but low prices.
