Ahhh, Ok, I see, I'll change that.... I wish there was a way to change ma. to Amps.. so easy to confuse me..

was charging at 10 amps, then 5 amps, it does it eitherway...

BUMP..... help...

Hey, all, I'm back... Can someone look at my settings, and tell me if anything might be causing the BMS to cycle while charging.. It charges, then drops out, then it resumes charging. it does this constantly.. I can't figure out why.. suggestions..

I got it figured out.. Yay! These BMS's are rebranded.. Took much time to find solution. It's working well, i just have to tweak the settings. I has to connect pins 14 +15 together to set it for 14s. Case closed...

I have a few JBD-SP15S020 BMS's They came with batteries i bought,. But no instructions. These BMS's are actually 15s BMS's But wired for 12s. From some place called RJXZS BMS. I discovered they were 15s by opening the cover. There is spaces open for more balance leads. but not present. And...

Hi all, I have one of these AIMS LCD remote displays. (REMOTELF) There's a button to the left of the display, turns the display off to save power.. But, How to i change it back to where the display stays on ? I've tried pressing it for a second, 2 seconds, double tapping..etc, I can't find any...

I think finally I got the info i need.. I'll try it this weekend. Yes, but that won't be an issue I'm not sure on that, as i have not powered them up yet. I still need to download the app as well. Yes, I have those as well.. 6 are in use on my other BMW battery Bank Gotchya.... Stay tuned...

Heres a few pictures The jumpers you see correspond to missing wires on the balance cable.. I can add in wires, but need to know which spots to remove the solder. The board is a 15s, but set up as 12s currently.

Hi.. do you happen to have the diagram for that 15s board ? the ones i got have RJXZS brand..but the board is a JBD-SP15S020 but it's set up for a 12s, and i'd like to convert it to a 14s... the boards balance connector has been soldered to be a 12s, so I'm looking for a diagram in hopes to...

No, it's just 1 balance connector. not 2 parts. I'm learning that this is a JBD-sp15s020 board.. I just gotta find the selectable options for it.. been looking for a while now..Hopefully i find out some info soon.

Anyone ever modify BMS's I have acquired 8 12s BMS's They are RJXZS Brand. I am hoping they can be modified. The circuit board actually says 15s, but some of the battery leads have been jumpered to make it 12s. I'm wondering if i could just unsolder the jumpers.. All the circuitry looks to be...

Well, From my experience, the inverter will have a constant draw until it has LVD. of course the amperage would increase if you went below that rate. I bought one of those Chinesium watt hour column meters, But it's not very accurate and hard to claibrate. I'm open to something easier and more...

Does anyone know of an inverter that has input voltage selection ? like 12v up to 48v selection? I'm looking for such an animal for using to load test batteries for capacity, as they maintain constant during discharge. Other devices ( dummy loads or such) current drops as voltage drops. and...

Not finished with it yet,, but i can post what i've done so far.. ( will post in the next day or so )
