Built a battery using 8 CATL 271AH 3.2 volt cells. I top balanced them to 3.6v in parallel. After this I built 2- 12v batteries and put them in parallel to yield 542ah with both batteries using a 120A overkill solar bms. Took out my 3-8D agm’s and installed the 2 lithium batteries and wired in...

Are you using the same charge profile for both inverter/charger and solar charger? What BMS did you end up using? I got 2 overkill 120a. One for each pack. New to this so need all the info I can get?

I bought 8-271 CATL cells from Michael Caro’s group buy. Trying to top balance the first 4 cells In parallel now. I do have solar on the Rv. So I will be charging from 3 different sources—Alternator, solar w/victron controller, and shore power through the Xantrex sw3012 inverter/charger. I am...

Read a lot of threads that said to store your lifopo4 battery at 50%-60% SOC. What is considered storage? 1 month of no use but still hooked up in the RV or is it 6+ months unhooked and sitting in your garage? My LifePo4 batteries will be used as the house batteries on my RV. The RV will sit...

Looking for help with the Charge profile and other items when I get the new batteries. Any help would be greatly appreciated. Thanks in advance. Current setup in 2000 Foretravel GV320 RV: 1120W of solar in parallel 2- Victron 100/50 MPPT solar controller with 560W each Xantrex FSW3000 inverter...

Read you can use the nylon banding material to clamp the batteries?? What do you recommend?

Saw this post of yours earlier in another thread and I would like your opinion on what size BMS I will need “Depends on your needed load. The current limit of the BMS will be the ultimate limit on battery performance. 3000W/12V = 250A” Looking to build a LifePo4 battery for an RV and ordered...

Looking to build a LifePo4 battery for an RV and was thinking of using 8-272AH cells for 2-12v 272ah in parallel for 544AH@12V total. I have run across some interesting articles posted on this forum and was wondering if the information below (#1&#2) is still the current and up to date view of...
