I have the Orion Twinspec, hooked up to a 46 amp Power supply. My batts are Orion 90c carbon Pro saddles 5500's..

When I try to charge at 11 amps the pack goes for about 5 minutes and then it says the pack is charged. It's not. If I lower the charger back to 5.5 amps the pack will continue to charge until it's truly done.

These packs are pretty much brand new, maybe 4 or 5 charges on each one at the most. What is the problem here? Why can't I get a complete charge at 11 amps. Before anyone that doesn't know responds.. Yes these packs should easily be charged at 11 amps.

I run a Protek 40 and have no issues with the same pack. Im going to throw this out there. Is it an adjustable/regulated power supply? I had an Integy 29a previous to the Protek and It was adjustable.

Have you tried charging from both channels? What do you have your power sharing set at?
