When I finally got fed up with their canned responses that it is on the way. They then wanted me to place a second order and pay for it. After that, they would refund the first purchase. I let them know that I was going to my credit card company and I would let them handle it. The same day, I...

I'm going to have to check and see what it would cost to get the plates machined. Or I wonder if I could just buy some copper bars and make my own. Then attach a post to it to mount the lug of the new cable to.

Has anyone replaced the 2 AWG power cables on the DALY 250A with 2/0 AWG cables? If you did, how did you attach the larger cables to it? My build is all 2/0 AWG to the bus bars and inverter. Not sure about those 2 AWG cables on the BMS. Would love to up them to 2/0 AWG so they are not the weak...

I have finally received it after finally having to threaten to go to my bank. It suddenly was delivered a few days later by DHL with a shipping date the same as the date I told them I was going to my bank. The one they sent by slow boat over 3 months ago that they kept telling me to be patient...

I'm not sure and never will be. What I want to plan for is if someone decides to plug something in that should not have been that the bars don't give me a problem. I want the BMS to do it's job before the bus bars melt or something. I have no problem paying more to oversize everything for safety.

If you find any, let me know as I'm looking for some too.

I have 4 280Ah EVE LiFePo4 cells to be wired to a 12v battery configuration. I need to get bus bars to connect the cells together. The BMS to be attached to the battery is a 250A BMS. The battery cells came with 4 bus bars but I keep reading they are not that good. Also I need enough bus bars...

Anyone know where I can buy a 250amp BMS from that is NOT Aliexpress?

The inverter I have is a 2000w/4000w surge. I originally ordered a 250A DALY but it never arrived. Any recommendations on a BMS to use with my setup? I wonder how battery makers decide what BMS to put in their batteries?

I'm really confused as to how to pick a BMS size. I am building a 12 volt 280Ah LiFePo4 battery. How do I select what size BMS to get?

That does show to use jumpers. But man the price of those Blue Sea switches is actually ridiculous. I usually like Blue Sea stuff, but not those switches.

Looks like that is what I am going to have to do. Was trying to avoid that. But...

That's what I have been searching on. So far, all the switches have 2 in 2 out. That's what's confusing me. Seems they don't make a 2 in 1 out switch.

Can anyone help with this? I can't seem to find a manual chageover switch that has 2 inputs and 1 output. All I can find is 2 input 2 output switches. Seems like this would be simple to find.

What has always confused me about this is if something expands, it takes the path of least resistance. So, if you compress the sides and the cells try to expand, it "seems" that the top or bottom of the cells would now be the path of least resistance.
