Sure Makes a Difference
Wow!!! just replaced the 2 1800 mah 7.2 volt nicd pack in my losi box with 2 7.4v 2s 15c 2600 mah lipos i got for 20 a piece at hobby town. Had plenty of trouble with new engines with the old batteries, not with these bad boys!! well worth the price, of course I already had the charger with a balancer but even if I didnt this would be worth it......
