Consider li-poing up since they are almost the norm at club races and now the Electric Pro Series is allowing them. They last a whole lot longer in cycles than nickel batteries, no cycling or discharging necessary, just charge them up and put them away to you need them next time.
Hopefully ROAR will catch up to the 21st century and allow them next year if they get Ernie P.'s permission from Trinity!
Just a suggestion!
