[RE-wrenches] Kit Solar

[Bradley Bassett]

An excellent idea and one that is catching on for DIY also. There is a
potential issue using those at below freezing temps, as with all Li
batteries they should not be charged at below freezing temps. You'd want to
look for one with heated batteries. There are more and more brands of these
power boxes available, but I'm not sure how many, if any, have heated
batteries. I'd hope that the heater would be powered only from a charging
source, but you'd probably have to ask the manufacturer. I think it's also
better to find and use those with LiFePO batteries for safety. For
industrial use it would be great to find something with the more expensive
LiTO batteries which are ok with lower temps, but I don't think there are
any battery banks with these, much less power boxes.
