Sunny Island SI-6048 BMS communication

Only takes energy to heat, not to keep warm. As you discovered when you insulated it. Maybe needed insulated enclosure and thermostatic vent.

Apparently insulation works for LiFePO4, just need a bit of electric heat, so even simpler.
I would consider if starting from scratch, but maybe only top name BMS like REC would be reliable? Even then, issues configuring.
I have strings of AGM for all.

D*mn!

I thought I had a line on 2x Sunny Islands and 2x Midnight Classics for cheap.

Victory! The (2)BMS, the SI6048, and the Whizbang Jr are showing SOC within 3% of one another

Of course, I'll probably have to start over with this every time I add another 200 amp hours of battery, which should be two more times this summer
