<p class="MsoNormal" style="margin-left:.5in">Hey Folks,<br>
<br>
I came across an off-gridder yesterday whom was getting zero support from the dealer he had purchased his small system from, self installed, batteries in a lightly insulated box outside. When I inspected the electrolyte levels I discovered it was frozen
in some cells, the voltage of the 48 volt pack was ~8 volts, I didn't check individual batteries due to these facts...I'd seen "enough". Recently temps have been in the high teens, though we are back up to low 30's.<br>
<br>
He does not have a genny or battery charger! I have a DC genny which I could use to charge these batteries but should I waste my time and his money trying to save them? Others' experience with this situation?<br>
<br>
TIA,<br>
<br>
Bill<br>
