Hello, Can't really find the answer to how a shunt can be wired with two Daly BMS. Here I wired the B- of the two BMS to the batteries' negatives. Bolted together the P- of the two BMS and joined them to the P- of the shunt. The B- of the shunt is then connect to a bus bar that allows fuse...
Hi Tavis, I ordered them off eBay 2019 came form San Diego. Just got around to to hooking everything up in Dec. Th 2000W inverter would shut down on start up. Found the negative cable on the battery using one lug was not tight,(bolt to long...saw your post of this) added copper washers. Now...
Yes the valence should handle the load, but they don't, I am ordering a load testing device to see what they can handle, this is the problem with buying use batteries. Now that LIfePo4 are getting so cheap from china there is no reason to buy used batteries.
I am look at buying 4x 280ah 3.2 V cells from China with a 300A Daly BMS, that is 1,120ahr v/s 260ahr from the valence. I have two U27-12XP that where used and they can not handle a 150amp/DC load. The cells from china are new and cheaper so that is the way to go, wish I knew this when I bought...
Yes I used a voltmeter at battery terminals, and inverter terminals , but the fuse only getting reading probe too fuse and probe too ground, this is a gold plated fuse with lugs torqued to 15ftlb (suggested) but its not what should be used, will replace with a high end T type fuse, since this is...
And Travis battery #1 show "1 error" and "1 under temp count," and "under temp for 128sec" can enlighten me to what this means? Is it related to charging?
Thanks Travis, think I will still place the lead acid batteries in the set up just to make sure the inverter is preforming as it should. Guess that is the gamble you take in buying used batteries off eBay, $850 lesson. Do you see anything on the read out that alerts you to the batteries being...
I will check all 3, I have had the voltmeter connected to the inverter terminals, and the voltage starts at 14 volts and drops very rapidly under a 130amp load, dropping to below 12 volts with in 2-3 mins under 82% load via inverter readout. The voltage via the battery software never goes below 12V.
Yes I have check all connections, ANL fuse/ holder does get hot, should be using a high end T type fuse. I am trying to rule out the inverter if it the problem I need to send it back , (1 year warranty )so I was thinking of hooking up my two wet cell batteries and see if the over load still...
