Yes I have tested
In fact if the battery voltage is higher than the float voltage of the victron, the mppt indicates a voltage but does not deliver anything in current.
Then I turn on the light and fan and there I see on the BMS that the battery is discharging and the mppt still delivers...
I'm asking because I haven't found anything concrete on the forum and maybe this could help others.
So I just finalized my new battery lifepo4 (replacing my old one (litokala and daly) with which I had big problems)
I have mounted a new 4S in 12V with EVE 280Ah cells.
I used the latest BMS JK...
I contacted Nami (via whatsapp), very nice.
They told me that the version of my BMS is an old version compatible only 8S, that I need to put a DC booster DC 12V-24V.
The old versions have 5 interfaces (connection) compatible 8S.
The new versions have all 6 interfaces compatible 4S.
Looking at the motherboard we see that it is version 9
Moreover I have the small LCD with the power button so I thought that by pressing the button the BMS should turn on
My battery is at 13,31 V so I have to put a load between P- and B+ of more than 15,31 volts
Is it safe for my battery...
Hi everyone,
I'm building a new battery (I've already built some)
I received my EVE280K cells
I did my top balance.
Then I wanted to connect my JK BMS (brand new) but it does not want to start
for information a small bracket was bent on the BMS (but nothing to do I think with the problem)...
i adjust the charge before.
The problem is solved.
After leaving a small load for a few hours the voltage went back down to 13.31 V.
The cells are at 3.275 V.
thanks
Okay that's what I was thinking of doing.
I plugged in a small 12V led (I only had this on hand) before leaving for work.
It consumes 0.41A.
I'll leave it plugged in for a few hours like this until the voltage is lowered.
I just received my new cells to make a new battery for my motorhome.
I have already installed one that works very well.
But now I have a problem.
I have connected my 4 cells in parallel to make a top balance.
I put my charger at 3.61V and 20A charge.
I left it for about 48 hours. My charger was...
Yes, this is certainly a better idea.
I think for the heating function I would do it completely apart from the bms with an independent electronic thermostat and heating pads.
Hi
I just ordered the bms.
But the seller advised me against the version with heating because it would be more fragile than the version without.
So I took the version b2a8s20p (instead of ba8s20p-h) 200A
