Well ive eaten the bullet, went ahead and ordered 2 new lifeline 300ah 6v's, found a great price on ebay and couldnt pass it up. I figure one way or the other im going to need to get some new batts. Still need to get clear on the entire system but im confident i can at least get the converter charger doing its job and at least for now everything will function for the time being. Ill spend some time this summer getting the charger controller and rest of stuff figured out. Still need advice on my setup so if anyone here can help i really appreciate any suggestions. Either way thanks a lot everyone!!
