After flipping the switch on the wall you measure the voltage on the battery, disconnect the cables front the frontpanel and remove the busbar between cell 8&9. Then you proceed to work on the internals.....
A point on the anti staic bags, they are only protective on the inside, the conductive layer that creates the Faraday cage is painted on the outside so laying circuits on antistatic bags can short components out, so I would not recomend doing it, I hope that helps,Take care D
I buy used lithiun that don,t work re placed the bms and replace them with a 8 to 10 amp balancer and they work fine, the controller and the inverter takes care of the rest, some of the bms are over 200. and they go bad poor in FL
quick solution that doesnt need a 3d printer, go to your local pound/euro shop and buy a cheap platic chopping board, and cut off of it a piece that is wide to fit in the gap, and superglue it into place where the weak spot is,you might need 2 pieces superglued together to get the same height as the standoffs though, a quick non conductive solution, and if your careful you will still have enough chopping board left to slice a french stick on :) :)
Whilst I understand you wanting to keep the same battery packs, I think it would make your channel more interesting if your had a different battery manufacturer to those you already have Sarah. It will, or may show some challenges to achieve this, but that is what its like out here in the real world. I have 2 Seplos Mason battery connected together and one is 10% down compared to the other. So the battery that is not getting a full charge is a bit of a concern, as I haven't even reach 300 cycles yet. So it would seem I have a bad cell in that battery pack, but I have no clue on how to find out which one it is!! Ken in Wales. Edit; I like those cut off switches, but not so keen on those loose cables dangling down, if you court it on something it could pull the cable out of the terminal. ( this happen to me once) You need to clamp them onto the wall.
I'm wondering if it didn't turn off initially because of the canbus cable. Also great that you took your watch off, but i would be more wary of your rings, assuming they are metal (Gold) either tape them up or take them off.
Thanks Sarah might be an idea to remove / tape your ring when elbow deep in the battery just in case and does the bms need re setting to your parameters ?
Then what is the point of the two long circuit board cell connectors? The balance leads from the BMS connect to the end connectors on the long circuit boards. The short leads from the circuit boards then connect to the cells in sequence. This is specifically designed to avoid the rats nest of leads down the centre of the battery. So why have the rats nest of leads and the circuit board cell connectors?

Very neat system & setup, set your grid point to around -60w, that way it will save a pound or so a month 'leaking' electric from the grid.

Great job on the thumbnail!
Excellent work, it's really fun to watch you analyze and solve problems!
Have you considered removing your ring when working inside one of these units?
Definitely! At 52 volts any metal being worn would explode if there was a mishap. Arc flash risk. Doesn't bear thinking about.

Gotta justify a 3d printer somehow. 😂

Please remember to disconnect all cables from the battery poles and remove any metal objects you are wearing.

Check the other standoffs, some boards make a shortage to the frame.
You can also upgrade the batteries without having to replace the case and BMS.

She didn't change the BMS.
Great work! Love watching your videos. You're using the quattro as the inverter, yes?
Can you see both your batteries on the Cerbo? I can’t with my two Seplos Batteries but I think it could be a BMS or Cerbo setting?
Over time the two batteries will become equal again.
Why are there all those red wires down the middle of the battery?
These are the balance cables coming from the BMS.
Yes, although there are safer ways to do that.

The short leads from the circuit boards then connect to the cells in sequence. This is specifically designed to avoid the rats nest of leads down the centre of the battery.

Thanks a lot for the video. Why was the active balancer necessary?

Board? get ride off this board install a JK BMS and a active balancer .
AFAIK the EEL cases come with the V2 JK BMS.
@@elminster8149 só just install an active balancer and get ride of the bord
Ciao Gridbuster I would be curious what maximum charging voltage you give to your 54.2 55.2 battery packs?
