I recently purchased a set of EVE LF280K battery cells. I have built similar spring-loaded compression clamps in the past, but the 1/4" steel plate which I used in those boxes would tend to bend around the cells if I used the same "just the plates" approach this time. I also increased the number...

It feels strange to ask about this configuration within the the solar-oriented forum, but here it is: Friends have asked me to recommend and possibly install a back-up only battery inverter-charger for their home, covering only bedroom lights plus a plug-in fan and kitchen lights plus the main...

Although some other threads talk about these cells, I'd like to focus on the terminal posts - which accept M6 screws at perhaps 3x the torque of into-the-cell M6-drilled "flat" terminals, but provide much less surface area at the top "lip" of each threaded post. See photo. Although my BMS on...

I ordered 4 "120Ah" cells from Basen at the end of March 2021, and they arrived about 10 days ago. I had received a matching Daly 4S BMS about earlier, due to faster shipping. After balancing the cells and building the battery pack, I'm seeing surprisingly GOOD performance. These were CATL...

Hi. I have two batteries packs, each is a relatively small 4S system with Daly "Smart BMS" 100A. I would like to tune these systems a bit better. They are installed in a travel trailer, in which I can either run the power Converter as "Lithium" (14.6V all the time, except when off) or AGM/GEL...

Hi. I will shortly be building a 120Ah, 12.8v LiFePO4 battery pack. I am unsure which "main" connector terminal to connect last (although I think that it should be "12V" battery lug and connector into the terminal into the "12V" Bus with two batteries already present.) Is it correct to do...

I have posted comments which describe my "Charge LFP batteries from the TV" solution in another Thread already, but that Thread's Title does not do a good job of explaining how this gets put together, and why it's typically better than using a DC-->DC charger "solution". This repeats that...

My first DIY battery will be a small one, 12.8v (4S) of CATL prismatic 120Ah cells. I bought the cells from Basen. On the forum, I read that I should probably compress these cells to about 6 PSI. Can some of you please review this scheme, and advise if I'll be making a 'misteek' by proceeding...

Good morning, I'm a new member. I see a few Threads about BMS boards without temp protection, and BMS boards "with temp protection" cut-off temperatures set too low. I have built the following system for my own RV (stored in a COLD garage through the Winter, and subject to cold AM temperatures...
