All right. Quick video today. I'm gonna test one of these balancers that I see everyone using this one right here. It will do quite a bit of sales all the way to 24 cells in this case.
I have this battery here that, uh, the cells are quite mismatched. They're not balanced at all. We put these this pack out of like just a bunch of random cells that we had from different packs and so that's a result of that. They're all right like that, right? So this little guy here which I usually use, uh, well, it's very slow, right? Um, and it only does eight cells.
So this is at a 10 cell pack. 10 in series, 42 volts maximum 36 volts, uh um, 36 volts what? Uh, nominal and uh, we needed to charge it because uh, we're gonna use it for forklift I'm trying to see how much runtime we get off our forklift with this uh pack right here and uh, but we need to balance it and I'm gonna put this here so let's see how long it takes for this uh balancer to work, right? So the thing is that this one doesn't show you anything, there's no information and I have this one here set up so that it can show me you see how unbalanced it is, right? So we'll come back in a few hours and then see how it's doing one hour later. All right. So here's about 24 hours later and the battery is all pretty much balance.
So at least within 23 million. Look at that guy, it does work. This was, uh, very, very unbalanced. Uh, yesterday.
And now here's something very interesting that's happened when you compare the before and after voltages and you put both of these screens side to side, you will see that cell one through five I get discharge, but cell number six gets charged. Uh, six and seven get charged and then eight again gets discharged. It kind of almost gets over discharged because now it's the lowest one after 24 hours. So this balancer here doesn't just burn energy like most of the other balancers that this particular unit seems to transfer energy from higher voltage cells to lower state of charge cells, right? So this is pretty good because then it's a better use of the energy that's available in the battery and you end up hopefully with a better balanced battery pack in a quicker time.
All right, Foreign.
I have no luck with aliexpress. They want to know my email password.
So its mean 10a on every string? Have you test it?
Hey Jehu I know you mostly focus on the electronics. Can you direct me to someone who would know about ANY KIND of seating a person could want in ANY KIND of VEHICLE (preferably a van) Or if you have a play list on any of that…? Thank You so much.
Jehu is there a balancer that can be custom in voltage? I have a couple of packs in LTO and i need to balance them but i need to set the voltages because is different from NMC and LFP…
Is there a possibility to program this balancer. E.g. Set a start and stop voltage?
Hi love your videos and trying to build a battery system for my Semi truck was going go with blutti because it’s easy but when I look it’s cheeper buying Lithium Iron Phosphate batteries is there a charger controller that you recommend and are they only for solar or can I connect it to a wall outlet I have a inverter in my Semi truck and when I’m driving I want to charge my batteries so I can use them when I’m not driving
OK so it was 16% SOC at start of test ,How is it showing 51% after 24hr , how has the SOC gone up ?
Seller says that it will do 96s battery pack good for EV diy ? anyway to have a display to monitor them ?
Good stuff. Thanks.
There’s a charger like this? Where you can charge every group and it’s up to idn, 20S…
Jehu.. Does it work for Lifepo4 batteries? can you test it
Could I hook this up in parallel with my Daly BMS?
awesome video.. i'm been looking for a good balancer for my LFP home DIY system that has a higher current rating for balancing.
That is cool but I think they should make one with a screen.
