Tony-I finally ran your IB3600 pack with a stock motor and you do have something good going on with your matching process of the IB cells. I dont know why your capacity is different than others-but they do have more rip than a GP cell up front. Get-em warm and keep-em warm through the charge process and dont let them sit pre-race.
Keep up the good research and development of these cells. I hope they become the main battery after ROAR approval.
