Sorry have had Internet issue's.
I have been told to charge at 20amp to increase the punch of the batteries,but my lrp batteries have the punch I needed. I race blinky 13.5 with the motor on 30 degree, which the club allows.
But I have read in magazines, forums that doing what I do is enough. But then I get a bit of dought , and have to ask you stupid question's to get some sense of it. Because I have swelled new battery's after a few months, but found out after getting both of my lrps check, it was a faulty batch of batteries.
