Any thoughts on using a breaker and its size?

I already had a breaker in mind, so it's a similar way as the manufacturer chose, external but as close as possible to the battery. With this breaker I have options for 125A, 160A, 200A, 225A and 250A. When I look at some existing LiFePo4 server rack or wall mount batteries, they usually have a...

According to the battery specs the peak current is 150 for a maximum of 2 minutes. Most likely this is an enforcement by the BMS. I also contacted the manufacturer about the fuse sizes and they told they were working on a new model of the same battery with an included circuit breaker of 200A...

I will use a 125A fuse on each battery. Maybe I will look into the MCCB mentioned earlier if there is a variant rated for 125A and with a high enough AIC (in the datasheet this is mentioned as Icu).

Did it work out? Do you have a link? Would it fit a Lynx Distributor?

The system I am currently working on will have a single inverter and 4 battery banks. The inverter is a Deye Hybrid 12kW 3 phase. According to its manual there is a 300A fuse needed for its battery connection. This inverter can charge or discharge with 240A at maximum. I am going to use a...

Yes, mine also disappeared from 17track. This resulted in my dispute being accepted by AliExpress. Now I'm waiting for my refund. The other dispute is still in waiting period, but as long as it doesn't reappear on 17track, I expect this one will be refunded too.

I read, but didn't find any message saying that the dispute refunded successfully. Maybe I misread. However, AliExpress stepped in on my dispute and they have it on hold now because it is still in protection time and ask me to wait. I am almost sure that I won't get any batteries and afraid I...

Did anyone successfully got a refund from a dispute? I am unfortunately in the same boat and have a dispute in progress. The seller sent a screenshot from 17track with a most likely fake QFL tracking number. If I had to believe it, the shipment reached NL customs by air transport (72 cells of...

Also bought from this seller, 8 cells Calb SE200Ah. Shipping took almost 5 months, but no taxes. They look like used cells, with scratched and stained terminals. But after capacity testing I got 216Ah. Opened a dispute, got a refund of 2%. Also bought their own brand BMS. Very low quality and...

I am looking for a way to mount a JBD 8S 100A bms somewhere nearby the batteries. Unlike Daly this bms has no holes for screwing. I don't want to tape it on the batteries. So I was looking for a way to either screw the bms to wood. Or even better to have some sort of enclosure. Anyone...

You mean something like these? https://a.aliexpress.com/_vMtM7L Would be nice if there is space available to solder these.
