BFL, my Northstar AGM craves high current recharges and will not do well on low and slow solar. It also costs 330$ and only has 91AH capacity. It could very well be my last AGM battery. If I do go AGM again, it will be lifeline, unless for some reason super high CCA ratings are required. My Northstar makes a great starting battery, which I don't mind cycling, when I can high amp recharge it the following day.
The current battery tray is already compromised, from rust and acid. It needs attention T-1275 or not.
I want a real deep cycle flooded battery, or at least the 12v battery which comes closest to this ideal. The T1275 should be way superior to any flooded 31.
I will make it fit. I'm trying to decide whether to retire the screwy31 today, or just lower charge voltages to the high 13's and monitor temps.
Seems I should just set it aside, for safety reasons.
The red arrow points to where the hood structure rested on the screwy 31. It was painted with liquid E tape.
Here is the hood structure, giving an Idea what type of modification will be required to it to accommodate the T1275 in combo with the lowered tray.
The Indentation the red arrow points to is obscured by the tape measure in that photo.
It won't need to stick out the top of the hood :) Which would be kind of hilarious.
