Hi. I have two Dakota Lithium 54AH batteries.
I emailed the company to ask about the BMS, and they replied that the BMS has high and low voltage cutoff, and high but not low temp cutoff. It seems absurd to me to put in a temp sensor and not also use it to keep the battery from being destroyed by charging at too low a temperature. So I'm wondering if maybe the guy I talked to has no clue and the low temp cutoff really is there. I want to find out.
What I would like to know is, if I freeze the battery really well and then connect a low amp (like 2 amp) charger through an ammeter for just a few seconds, will this damage the battery? I'm ass-uming that if the cutoff is actually there I should see no current going to the battery and if there is any current the cutoff is not there. How am I doing so far?
Next question, I searched but got lots of conflicting information. With my Victron MPPT 100/30, if the PV is putting out power and the Victron is charging the batteries, and the BMS disconnects the battery or I mistakenly flip the breaker between the Victron and batteries, will this cause harm to the Victron. I didn't see anything in the manual other than to connect the batteries first and the PV second.
Thanks!
