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.

I have seen some complaints about Daly, (in fact I have seen complaints about every BMS) but everyone I personally know that have used them have had very good results with them. I'll keep my fingers crossed that I do to.

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

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 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...

Have not purchased one yet. Still designing. It will most likely be a Blue Sea Systems busbar.

I know I am confused. Compress cells or not. Foam between cells or not. Hmmm...

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...

It's way past 2 weeks. The delivery date was suppose to be the 21st. All I can get out of DALY is..... wait my friend, it is on it's way. They sound like a broken record.

I have a 12 volt LiFePo4 battery I built using EVE 289Ah cells. It is goin in a van with solar power. I want the option of connecting to shore power when available. I'm getting confused as to what battery charger I should get for this purpose. Anyone have any recommendations on a charger under...

I was wanting to get a Blue Sea brand busbar but they seem to jump from 150A to 600A My battery is fused at 250A so I figured all I really need is a 300A busbar. Can anyone recommend a good quality 300A busbar?

Says shipped by Aliexpress premium shipping. Last update was 4/4/2021 and says Delivering - Shipment accepted by airline Ordered through DALY Official Store

Thanks everyone. The responses have helped to clear up any confusion I had. I'm learning slowly. :)

12 volt

Don't know yet. Still waiting for it to be delivered. Hoping it gets here in the next week or so.

I went over to the PD site and they are now saying if you buy one manufactured in 2021 it now has 2 stage charging. It holds at 13.6 after the battery is charged. So it seems the lithium one may now be fine. Hmmm.... I'm still confused but getting there. :)

Can someone please check to see if I got this right? I have 6 - 100watt solar panels Short circuit current of panel is 5.86A Max series fuse rating is 15A I am wiring these 6 panels in a 2S3P configuration. My calculations are showing 17.58A is the short circuit current for this array setup...

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?

Thanks. Did not think of the total left in the working sets. Also the Voc of each panel is 22.3v so we are only talking 44.6v coming out of the array. So if I added one more series set, then the fusing would be needed. I think.

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

I thought you had to use a charger that was designed for LiFePo4 batteries? So it's OK to use one that is not?

If I have a busbar with 6 lugs but have to connect 8 wires to it, can you put 2 wires on a single lug? Of course the busbar would be rated to handle maximum amp load of the system.

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.

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...

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.

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.

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?

I have been reading reviews on manual AC transfer switches and reviews are all over the place. Prices are too. I need one to switch between a 30AMP shore power connection and the inverter. Anyone have a recommendation for one that they trust will do the job and not go up in smoke? :)

Thanks. I'm learning something.

I paid extra for the faster shipping that said it would be here between the 15th and 21st. That sure did not work out and can't seem to get any response from them except to wait it's on the way. Thinking I may need to escalate it to a refund claim with aliexpress to get their attention and a...
