This looks interesting, and some safety aspects really caught my eye.
Essentially a 12v / 60 or 100ah 4S LFP project. The big thing to me that might help success is the casing and support for these aluminum-can cells. I'm not so much turned on by the "air" spacing, but moreso the physical spacing between the cells because you REALLY don't want skinned aluminum cases touching each other!
Hey, at least this guy is wearing glasses. He's moving too fast for my tastes, and should leave the glasses on a bit longer.
They appear to be made from these EV cells in either 60 or 100ah
SAFETY is what caught my eye for a DIY'er. Despite the case providing some real protection, PLEASE people, insulate, plasti-dip, or do whatever to cover everything but the head of the tool. But at least when all is said and done, the terminals seem well protected, and cell casing bolted together to avoid side-torque issues from just running a single strip of kapton tape around the whole thing.
Personally, I'd *clean* the links prior to assembly. But it is nice to see hardware that will allow the standard diy'er to get a proper torque on these things without damaging the cells in the process.
So the choice is yours - add a bms for protection and passive balancing. Or in my case, YOU are the bms (costly if you blow it!). Or in the case of a wheelchair user, use *active* balancing on charge, say with a Revolectrix PL8 and some LFP specific software - go to wheelchairdriver . com for more information.
To me, this is a FAR better solution if one is going to DIY, than grabbing a bunch of random junk off the net. I cannot vouch for the quality of the cells, nor do I have any business with these EV guys, but the engineering seen in the casing really turns me on from a SAFETY aspect.

Likewise using power-type lfp's to start your car is, um, a non-starter unless you totally go overboard in capacity.
