I thought I just saw amain just came out with a protek charger that does like 10 amps and it works for the lihv batts and like every other battery ever made. Was thinking about getting it since I run the lihv square packs. You could just do an icharger and charge up to the 8.6v range by adjusting the charging voltage. Just can't charge up to that for racing. I'd be curious to see how much of an increase it would offer though and see how much faster my lap times are.
