HELP System fault C2

[Leander]

In my case this, I've just replaced (today) 3 high voltage fuses, and it's charging again. Also replaced 100 batteries, removed the ones with less capacity by new ones....

Which fuses did you use?

Hi Leander, not as the same as the ones from factory. I used a regular ones of 15A not the slow ones. I installed them, and it started charging again, so for the moment it's fine

Hi Patrick, what new cells did you use and where did you find them please? Also what was the physical condition of the busbars and cells. Thanks

Hi Patrick, what new cells did you use and where did you find them please? Also what was the physical condition of the busbars and cells. Thanks

Hi, some of them were totally depleated (3 un) 150 units had less than 5Amph, the remaning 100 units were above 5Amph but less than 7Amph.
Some were a bit inflated, those ones I removed also, because it was dificult to put them inside the module.
I also sprayed some sort of moister protector (varnish on the BMS Boards) to ptotect them from corrosion.
I don't know what are busbars (or at least don't recognize the word)
Now I know what they are.... someone share this site and there they were, number 7 on page 6. Mine were very good. But I replaced already two connectors of the BMS board that connect to cables 4 and 5.

With the old batteries I made a costumized battery pack for my solar system

I bought them from alibaba and aliexpress. If you search for this 3.7v 9759156 10Ah cells on alibaba (or simillar but you need to order 160mmx60mmx10mm), right now the seller has no more available.

On aliexpress, you must say that you want the ones with 10Amph, because I had to complain with them, because they sent me 10 units of 8Amph
