No there is no fix to lower the delta peak, as per what I was told by CE. But like was previously stated, the peak drop it 40mv, and thats what I use on all my packs unless its really hot out. Its a good secondary charger.
I had to stop using mine though, as it get hot halfway through each charge and then shuts off. Only fix is to use a fan, but I have yet to find a way to do it so it looks good.
