    Help me confirm my setup (3x 16s1p 280Ah)

    I did hand tightened these at 3.000V. Do you think I've damaged the cells by that?

    Talk about not having a clue lmao.

    Help me confirm my setup (3x 16s1p 280Ah)

    It's 40A on 16 cells. Surely this wouldn't cause the light swelling?

    Help me confirm my setup (3x 16s1p 280Ah)

    Hi, I'm charging the 1st pack and I do wonder does this still look ok to you? I aligned the cells as best as I can do. The difference between the sides is 0.5mm max. But the cells aren't perfectly aligned (about 50% charge). Is this something I should be concerned with? Looks like a very...

    Help me confirm my setup (3x 16s1p 280Ah)

    Good idea. I reckon it will be just a few N⋅m (single digit ft⋅lb) fortunately I've bought a very small torque wrench for stuff like battery terminals and fuse terminals so I can dial that down pretty accurately. It'll take some time tho. Should've bought more powerful battery tester. That...

    Help me confirm my setup (3x 16s1p 280Ah)

    Hi, for my sanity sake please do help me confirm the correct order of actions for my packs. It's 3 packs of 16 cells each, on custom made stainless steel rack, shelves made of Cetris (essentially sawdust and concrete), end plates made from 15mm (1/2 inch-ish) Pertinax (FR-2? in the US?) with...

    How many 280A LiFePO4 cells can you put in series?

    Expensive and there is few choices out there? Sure. But hard? I don't really understand what issue do you have.

    How many 280A LiFePO4 cells can you put in series?

    I have separate 16S banks connected in parallel. It's single phase. It was more cost effective to rewire my stuff into single phase (or simply get a VFD) than going thought the trouble of 3 phase setup (and still having to deal with spikes from motor starting up). Plus I'm a BIG advocate of...

    How many 280A LiFePO4 cells can you put in series?

    Old MultiPluses? Yes. The new ones look like some aliexpress specials tho.

    How many 280A LiFePO4 cells can you put in series?

    I'm at like 80-90kWh with packs of 280Ah EVE cells from Amy and I'm going the 48V route if only because it's an extremely common and still safe voltage range.

    How many 280A LiFePO4 cells can you put in series?

    Yes, people do build these. Yes it works. It opens a whole can of worms tho and I'm not sure it's actually that much cheaper than 3 inverters connected together.

    Is it possible to use a 120v relay as an automatic transfer switch?

    BTW this is how Victron does it. It's just a 2NO+2NC contractor and some stuff around it in a box.

    Mitsubishi phev BMS

    It's been some time since I've stumbled upon that project while looking for a way to add another battery pack to my MIEV. Unfortunately I didn't save it. Should be pretty easy thing to google tho.

    Mitsubishi phev BMS

    There are open hardware BMS that can be used with those designed specifically for the MIEV. Also there is A LOT of info for those MIEV packs (Outlander packs in this case).

    Is it possible to use a 120v relay as an automatic transfer switch?

    My concept is specifically designed for like 1-2 sec transfer times. It's not really for a fridge or anything. I've had in mind my EV charger, the battery bank chargers and the water heaters I have. All devices that aren't very transfer time sensitive.
