Well then the only other thing you can do is set your TCS for 60%. Only problem with that is you'll have to remember to put it back to 100% when you want a full charge.
Might be time to consider an exchange, I really doubt it's a firmware issue.
even with the tcs set at 60% it will not discharge a pack to store mode. i need to do it with the discharge function and just set the discharge rate of each cell at 3.7. if i set it on 60% and have it as continue action it will carry on to charge to 100% anyways, so thats not a big deal im just baffled. should have stuck with the turnigy 8150 i guess
