I bought 2 4A chargers and two 9AH LifePO4 from stark. Batteries work fine, but the charger will blow a 5Amp fuse when the battery is first plugged in. I am a little worried about putting a higher amperage fuse in the battery. Anyone else have this experience with the stark chargers?

I have a 5A charger (the original Silver one with the fan from Knauff and Grove (I was an early adopter when an SLA failed at the Ridge); now they have the black ones) and two 9AH LiFePO Stark batteries; had them all for two years, never blown a 5A auto fuse on battery or the charger fuse. I use 16 AWG cable.
