Sorry for the lack of clarity. My main concern here is the fact that the amperage on the power supply still has never dropped to zero, which means it has still been taking a charge even after 10 days. It should have gone from zero to full after about four and a half days. And yes, I disconnected...
The reason I have been wanting to find someone with a charging unit rather than ordering one for myself is that I'm in Mexico and as far as I know, Amazon is basically the option to acquire something like that where I am. But it would take a week or more to have it shipped, and I really don't...
I'll copy my post to a new thread... But for the record I'm doing it the way Will shows in his video (+ and - on cell 1).
I actually decided it might be better to charge them individually, which I'm doing now...
Yes, I accidentally hit the post button when I wasn't finished typing it all yet. It's a "Daly" bms (although it doesn't say Daly) from Alibaba. And what's even more puzzling is that just now, somehow after less than an hour of sunlight, the battery seems to suddenly be in full working order...
I've seen some other forum threads on the matter, but the ones I've come across have been rather specific for other setups different from mine (8s, 16s, 24v, etc) - and, since there are different BMS models for each different type of setup, it seemed prudent to ask about mine.
Thank you for this reply. I was looking at the other linked Forum thread from the Hightech Labs recommendation. It looks like most of the stuff on that thread is about jbd products, and I couldn't tell from the pictures posted by the high-tech person whether they were selling stuff they produce...
That's great to know. What do you think the maximum safe amperage is to charge one of these? I just called the auto parts store and they said they have a 12-volt charger with an 800 Peak amperage, which sounds insane to me but maybe that's safe?
The voltage I'm reading at the clips is 3.31 or 3.32, while it's all connected. As far as measuring current, I have access to a clamp meter but I've never used one and after watching a couple of YouTube videos I don't think I'm doing this right, because all I'm getting when I put the clamp...
Whaaaat? Wow, I had no idea, lol... are there any other differences? The overkill ones are sold with 8 gauge cables on them, but I thought I saw another post saying the jbd ones don't come with cables...
It's a 12 volt battery system. I'm not sure about your last question because I'm not sure if or when it has hit its highest level of charge. The Daly BMS app notoriously doesn't give an accurate read on the SOC. But yes I just checked and the multimeter agrees with the BMS app: cells 2, 3 and 4...
OK, I'm still puzzled because this thing has been connected for well over four days and the amperage still has not dropped. And, oddly enough, the voltage has risen to 3.66 instead of 3.65 where it's been for days. That's not bad, is it? How long should I let this thing sit on this charger...
But as far as the tiny reading I've been getting, the reading honestly bounces around that much - or more - all by itself without the clamp even being around anything.
My problem, though, is that they are not at full charge. I only have a 5 amp charging unit and I've only had a couple of days to try and get my act together before hitting the road again. I tried charging each cell with my 5 amp bench power supply at 3.6 volts, but it was taking so long on each...
I've been looking at Alibaba too. The prices are pretty much impossible to beat. But I don't know very much about batteries; I know lifepo4 batteries are better than other kinds, so that's what I've been looking at. But I've gathered there are several different types of cells, and I don't know...
One problem I'm having is that the BMS is telling me it's 100% charged already, even though I know it's not. So I'm not even sure how fully charged it actually is as a pack right now. the isolator connected it's been getting 30 to 40 amps of continuous charge while I've been driving, and I have...
At 20 amps, plugging it in for 10 hours should juice it up to about 200 amp hours, right? Since the battery is already partially charged, I'm hoping that plugging it in now means topping it off by morning.
I'm quite curious about this comparison too. I'm about to place an order and I'm debating between the Eve and the Lishen cells. Apparently the Lishen cells are advertised at 272ah, compared to the 280ah Eves... even though sometimes the lishen ones can measure at higher capacity than the Eve...
Apologies if this seems snarky (not intended), but I'm not sure how my previous comment didn't clearly answer this. Yes, it agrees that cell 1 is bouncing up and down in voltage.
I'm not sure what grub screws are, but I'm using the parts that came along with the cells. Everything is brand new...
