Need a new charger - 2010 GEM e4

I have a 2010 Gem e4, it looks like I need to replace the charger (DeltaQ 72V) as I am getting the flashing turtle and 6 blinking red lights on the charger.

I pulled all the batteries and had them all load tested and fully charged, all are fine (only 6 months old), verified all the connections are secure, replaced the power cable, i think I covered all my bases. Am I missing anything?

Any recommended replacement chargers that are not going to kill my wallet? Is this a DIY project? I am pretty skilled, not ASE certified :). EDIT: I have wet cell batteries.

Send your charger in to FSIP and get it repaired.


Thanks, I contacted them and they seemed great.

Any tips or link to instructions on removal?
