Hello all, I have 2 sets of Concorde Sun-Extender batts I installed in the one and only Richard Perez' home about 4 years ago. One 12v pack and one 24v pack. No signs of anything kinky. I try to Re-torque terminals every 1-2 years. I will probably re-torque them again next week when I visit.
Cheers wrenches!
