I was beginning to have some issues with my original Interstate SRM29 batteries. I decided to go with Ionic Lithium’s. Three 50ah and a 125ah. Total weight reduction after replacing the 3 interstates, a X2Power 31m, and a NOCO Gen4 charger was 179 pounds. Please excuse all the dirt and grime. I haven’t had a chance to seal all the old holes and wipe everything down yet. I’ll get that done after water testing it next Sat. morning.
