Ken you can use any modern smart charger i.e. ones that auto sense voltage. and I charge at a c10 rate.

The actual chargers I use are the same three that I charge everything with including 1.2 volt ni starters. They are two Pro Peak Prodigy 11 and one Mystery charger the mystery is a fifty buck unit that was what HK sold before the BC6 or whatever they call it now.

The cells in the ten dollar battery are 1.2 Nicds and they work great for perhaps no more than two day. This battery offers Voltage and I have always said when it comes to starters, voltage is king. If the fellows want a battery that lasts for weeks this this is not for them, ya gotta charge it.

We are just now over forty members and becomeing even more active than ever and since I first discoverd this ten dollar battery over half of our member have made simple conversions with it. Thats because its the best bang/performance for the buck.

I no longer use the 16.8volt conversion I have used for years which were excellent performers but the conversion was difficult just attaching two seven cell Nimh packs in series and though up to 5000 Mah with some that setup was quite expensive.

The simple act of attaching this Harbour Frieght battery is so, simple that last one I pictured look close. That is just a block of balsa between the battery and the motor case. I carved a concave surface to fit the motor and the battery side is just flat. There is nothing holding the assembly together except RTV or silicon seal (takes twenty four hours to fully set before handling). There is no strength issues with using the glue (do not use epoxy, that is too brittle) I have dropped mine wheelchair height to the desert floor to many times with no bonding issues.

I also do not use Lipo because the issue with others constantly borrowing your starter. There is no way to convienently keep track of you batterys charge status an avoiding a deep discharge which will destroy that expensive battery almost instantly. Also if one choose to use the three cell lipo you are stuck with even less voltage and a starter that is going to be even more whimpy that the old twelve volt cell holder that folks are even still buying to this day.
