Think of the time required to pull batteries once or twice a year and charge them up individually as BB recommends to prevent the runaway battery problem and keeping the batteries in balance.Yes, using 12 volt Battleborn batteries in a complex serial parallel arrangement.
Do you have to pull the batteries apart? Can't you just charge them all to 100%, wait for HVD, then charge up the low ones individually to match? Shouldnt have to disassemble.Think of the time required to pull batteries once or twice a year and charge them up individually as BB recommends to prevent the runaway battery problem and keeping the batteries in balance.
As long as they are all accessible that is...Shouldnt have to disassemble.
What do you think? Start right here.Do you have to pull the batteries apart? Can't you just charge them all to 100%, wait for HVD, then charge up the low ones individually to match? Shouldnt have to disassemble.
Yeah all the terminals are all front and center there. It looks pretty simple.What do you think? Start right here.

This is nothing more than marketing.Don't get me wrong, 4s x 12v batteries is a stupid idea, no matter how you twist it.
I don't understand why you would have to break them apart? It's just like charging individual cells in a 16s battery to quickly balance. You connect a bench power supply to the + and - of each individual battery and top up whatever one is low.You still have to break it down, charge each battery and put it back together.
Not my thing........

Yup4x12v battery equalizer would solve the balancing issue for few bucks
I was able to catch the video minutes after it posted. It was surprising and very concerning. I think they should repost it, could be a recall type issue.You can find various discussions about that video on the web but the video was scrubbed. This was a discussion in this forum.
And here is another thread.

Will never happen. There will be an epic eventual failure followed by an epic lawsuit.Think of the time required to pull batteries once or twice a year and charge them up individually as BB recommends to prevent the runaway battery problem and keeping the batteries in balance.
That doesnt matter much though, it is the series of the system that is important, otherwise you could say that a LiFePO4 128S is just 3.2V instead of the +400V? As soon as you put the batteries in series you increase voltage and reduce the Amp hence need for thick cables. So I would say that this is a 48V system but as soon as you need over 12kW from the storage (no matter if it is 15kwh or 200kWh) you should consider a HV Hybrid or HV off grid inverter instead of 48V and crank it up to atleast 64SxP to not be forced to use Frankenstein cables, fuses and connectors.The individual batteries are 12 volt
Not quite. It's actually 4 12v BMS controlled batteries in series.That doesnt matter much though, it is the series of the system that is important, otherwise you could say that a LiFePO4 128S is just 3.2V instead of the +400V?
Exactly. The BMSs are the issue. IF you could somehow connect all of the BMSs together so they talk to each other and work as one, this wouldn't be an issue.Not quite. It's actually 4 12v BMS controlled batteries in series.
The issues are with multiple BMS's in series, causing imbalance.
The voltage of the battery (and BMS) should be the same as the system.
