Is there a faster way to charge receiver packs then the little charger that comes with RTR kits?
You can use any charger that is capable of doing 5 cell ni-mh packs. Something like this would do good, but there are a lot of options out there.
4wd Sportmaxx 3.3
E-Revo - Mamba Monster - Neu 4s
Keep in mind about the fastest that they can be charged is roughly 1 hour.
Whatever it is I just typed... could be wrong.
