Li batteries at 48vdc
After much deliberation and questions, I'll likely be purchasing the 48v Lithium battery pack instead of 4-12v. I liked the idea of 12v batteries for weight and ease of handling, but the possible cel...

Hi brulaz,
I think part of the problem is the choice of inverter. My Magnum doesn't alarm until a much lower voltage than my tiny 400 watt Canadian tire unit.
Not much cheaper for carbon foam when you have to buy 4 to get to 48 volts.
They are similar in weight to AGM or flooded jars.
Voltage sag is better than flooded and probably similar to AGM.

Wondering if you considered Firefly Carbon Foam?
They have a sealed 110Ah 12V Grp 31 batt that's remarkably resistant to sulfation. Cheaper than Li-ion.
Not sure what the voltage sag is like at various SOC though.
Li-ion voltages are so stable, they're hard to beat on that.
