Volta Power Systems - 48volt Battery Pack

[Davydd]

We have been over this time an time again. Specifically to the Volta system:

Minimum Charge Temperature is -32F
Minimum Discharge Temperature is -4F
Minimum Storage Temperature is -4F

Underway most Volta systems I have seen are inside the van in a controlled environment and if you maintain that environment underway you can charge and discharge.

If you have lithium batteries in most of the United States you should have a minimum of shore power with a method of maintaining temperatures above 41F. Electric resistant heating pads are probably the most efficient method and you don't need much amp hour rating pads to do so. Most all lithium battery banks are high wattage and getting heat can be from your batteries underway with no problem. Or you should store inside in a controlled environment. If you don't already know this or can't achieve this, then you are not a candidate for lithium ion batteries.

If you live in an environment that will not go below -4F you can disconnect your lithium batteries and store all winter safely without shore power. I doubt you could do that with AGMs.
