RE: HPI Baja 5B-Receiver Battery/Charger ?
I never used the wall charger with my Baja. Actually, I never used the original battery either. You can use any charger as long as it can charge 5 cell Nicd/Nimh batteries and has an adjustable charge rate. HPI has a new high capacity battery for the Baja, or you could get one from Promatch also.
