When the bms is turned off and I probe the battery positive and bms “P - (minus)“ shouldn’t it read 0 volts? I’m reading 12v which doesn’t make sense because it’s turned off 🤔
Bonjour de France... Je suis en train d'installer une batterie comme la votre, serait il possible d'avoir le plan de connection de votre disjoncteur. Merci beaucoup. Pascal
I will be running a 24 volt system, I want to run 16 3.2volt cells configured to 24 volts, I have two of these batteries.. a total of 32 cells. the cells are rated at 280 ah. My MPPT is a 250/80 viltron unit. and I am running 4-540 watt solar panels on the roof of my motorhome. My inverter charger is a viltron 3000/24/70. I am trying to figure out which JK BMS I should run on each of these batteries.
Hi, I have 16 cells running in parallel pairs of two (like you have 8 cells here running as 4 cells to 12v). The total voltage is 24v for my system. Should I connect each BMS wire to each cell or each parallel paired cell like you have in this video? What happens if you get a rogue cell that affects the pair? Thanks
Hello! For the layout of the BMS and most BMS's, the balance wire is only able to balance with "one" cell. So you'd have to connect two cells in paralell for the required setup you need. So yes for wiring up the balancing cable you'd connect it to the paired cells like in our video. Plently of our LiFePO4 batteries has this paired layout and it is able to work with eachother well in paralell together. I hope this helps
I just bought a B2A24S2OP looking at the wire size 2 8 Gauge wire how can it handle 200 amps continually. 8 AWG wire can handle 55 amps each so two in parallel would be about 120 amps not 200. This thing says it can go to 350 max can't see how this wire can do that. The video your is much heavier connections.
I have 2 Jk bms in my system and think they're great. The only feature I wish they had was current limiting when the cells are near full charge so you can charge slowly while balancing instead of it having one cell hit your set voltage and fully stopping charging even though other cells will accept more.
Sounds as though you pack is significantly out of balance, so to reduce the likelihood of a fully charged runaway cell tripping BMS over cell voltage (3.65v) reduce your charger pack voltage ~14V and check that balancing is activated. Now leave battery balancing and watch delta V reduce from 100-200mV and once delta V is <20mV push up pack voltage to 14.2 then 14.4V and eventually you have a balanced pack. Need a charger with variable voltage.
I see the way he orientated one of the cells which could short out against the cells running parallel to each other. I can't see a BMS, if it hidden then maybe it was to big for the cells?.
Also is he using cable to connect the cells? They look to be different lengths and thickness, lots of resistance will cause excessive heat and then the cell will degas.🥳
Hard to hear your voice; it is tinny. When you move around the volume changes. My suggestion is to get a dedicated mic for you to wear. Content of hte video was pretty decent.
Hey guys, Davi b here, how is it all going? Ive sent a few people to your shop, i was rather impressed with your products, my 12v 200ah ss casing, life po battery is faultless, in fact being in Western Ausie at this moment, i am going to ask would you like to sponser a 300 ah for me to show off over here, i think it would be great move? Im in the heart of the 4wd territory, hear from you soon, davi b,
Hello Dave! Glad to hear about how you're loving our BWB 12V 200AH LiFePO4 Battery. We have increased orders for our LiFePO4 in NSW & WA. So far, they too are happy about their purchase.
