Well the only options are you have a bad BMS from the factory, the charger isn't set to high enough voltage for charging, one of your charge parameters isn't right and too low or the pack is not balanced and it's sending one cell into high volt cut off before the the rest of the pack is there...

Yeah I'm pretty sure you do it just like you suggested, use it as a separate charger and just hook it up to the main positive and negative. That way you can get more wattage in without going through the almost maxed out solar inverter.

So the batteries are 310 amp hour prismatic sales that are in series to make one giant 48 volt battery. 16 gives you a lot of options whether you want to go four packs of four two packs of eight one pack of 16. It also lets you choose if you want to go 12 24 or 48 volt. I could have made it much...

That seems a little high. Considering the average home uses 800kwh +/- per month lol. You mean 6 or 62? I made a 16s system out of 310s with a eco worthy solar hybrid inverter and 6 250w panels. I didn't make it with anything in mind other than 310s were available and reasonably priced. I did a...

Yea I must have the generation just before that. Mine is asleep whenever I go to my shop but to wake it up I just unplug my hybrid inverter and plug it back in and it wakes it up.

Yay! Are you getting a status code or whatever its called? Before my pack was situated it'd be one cell that would be too high and give me the single cell over volt alert. Of course. Happy to help.

Sounds like you made the right first move and returned the old one, I've had no issues with my daly 16s 100a coupled with the 16s balancer off amazon, I forgot the brand around 80 bucks. But after a proper top balance my bank will sit at 56.1 or so with 005 differential.

Pretty sure that happened. My system isn't in use really, I made it to offset a generator if a long term outage occurs. So it just sits on my bench cycling on and off from charging. I noticed the other day checking the app that I hit a high cell alarm with one cell hitting 3.65 while charging...

How you make out?

I did and basically attribute it to the balancer. I also had to actually top balance my cells. I thought they were but weren't.

Awesome. To not work them below 3.4 I guess I'd just unplug it? There is no on off switch. If voltage equalization accuracy is the same as deviation spec it's listed as 5mv. What's that mean?

Initially yea. In the beginning I didn't understand the difference between being "balanced" at say 3.33 and then actually being top balanced at 3.65. So then it was my bms stopping the charge when one cell would hit hvd. But I think I'm decent now. Appreciate it.

I understand that cells will settle after being charged or discharged I've never seen a battery that doesn't. What I didn't get and get now is that although all of my cells were say 3.33 at the same time they were not balanced when I thought they were. It took a while to understand that they...

Good to know I think. Still learning about these batteries. Idk whats up with my setup. Its not unusable, I did draw 31a dc out of it over 9 hours which came to something 275ah out of an advertised 310ah capacity then whatever room is supposed to be left to not discharge fully I think I was...

No. You wrote earlier about it taking single digit minutes to bring the lower cells to 3.65 that doesn't happen in my case. If I'm doing it right and not disconnecting anything leaving the pack and it's 16s configuration putting the power supply on One battery at 3.65 volts and 10 amps it didn't...

I appreciate your responses and more so having patience with me as I learn. I got home from work and ran a heat gun for a little bit while I cleaned up and this is where the pack is at now I left it unplugged so the charger won't kick in. Would you suggest I plug the charger back in and bring...

Yea its no Kubota or Bobcat but you can certainly dig a fish pond or some holes for some Leyland's no problem.

Yes of course.

Yea I understand. I did one cell over night to 3.65 and the switched it to another before work. I may have not explained it right before but I'm pretty confident by the time I get to the 7th cell, my first I got up to 3.65 will be in the 3.4s and sequentially up to the one I'm working on. And...

Ok I got that, so then am I not getting the full potential of my pack since they cant seem to hold a balance after 54v or so? What's the remedy for this if there is one or just have it be at a slightly lower voltage than others I see here?

Somewhat back to where I was before when I initially sought out advice a couple weeks back here. I set those voltages and now one or two cells reached high voltage shut off and the BMS stopped the charging. I think I'm at 54.1 right now. With .134 difference or something like that. I can't get...

Yea its definitely considerably louder but for me it doesn't really matter. I run whatever I have in my detached garage with both doors open. Building absorbs most all the noise.

Most made on the same street or even in the same factory overseas. I love the people who will comment on craftsman tools posts on FB saying "but where is it made??" China, the same place as your, phone, tv, laptop and a plethora of other things you own.

I've had predator 3500s for years, since they came out and were $589 with a coupon. No issues at all.

That are complete trash, I worked for the DOD as a inspector troubleshooting these. Square wave, over priced, no redeeming qualities at all. Military stuff is just made by the lowest bidder, you could buy 5 eu2200is for the price of one "Military" 2k and they'd last infinitely longer and are far...

Yea its a nice one. Honestly I'd go for the size down thats still 220 but open frame and still an inverter for $800 less or so.

....not me. lol today years old. So ring terminals on both ends and 10 wire should unlock the 10a capability of my dc suppy?

Flagship model. I've read a lot about them. None in my local store but I couldn't justify having it. I'm fine with my little predator 3500. Very nice, best of luck.

Did you keep the stock male plug that goes into the supply? Trying to picture your wire.

Thats where my pack was hanging after I adjusted settings last week when you first gave me advice.

Ok thanks. I don't use this daily or at all. It's just to take the place of a generator in a long term outage situation. I don't think I could do 53.5 since my charger only goes in .4 incriments.

Idk its brand new, I've seen it put out 10 when I hook it to a drill or dead car battery and raise voltage just not at this low cell voltage. So then how does one do this and keep them up while charging others. I did it with no load just connected to the charger but the charger wasn't charging...

Thanks for the info thanks, appreciate it. Struggling to understand difference between lvd and balance. Yes I used a 30/5 and a 30/10 to initially top balance. I tried that but when one would be good I'd move to another and by the time I had say 8 up to 3.65 the first one would be falling to...

After my test I started charging it back up with setting the boost and charge voltage a little higher. It was still charging when I checked it before bed and in the morning it was off and settled at 54.0v. No bms code kicked in which is good but I'm back to a not great balance of .150, not as...
