Rechargeables are better than alkilines, not to mention more economical. Usually on a full charge, and depending on capacity, they will last about 3 days of racing, I would try to get 2600mah, bats.
I personaly use a lipo on my 3PK, and has lasted since last charge about a month of racing every sunday. Lipos are way better IMO.
AKA El Pibe RUFAST? HAHA!!!
