One thing I’ve observed in lifepo4 youtube is that everything is just assembled, there’s no original design anywhere. This type of cell, that type of bus bar, this bms, that sensor, this casing, that terminal. It’s all put together like children’s blocks.
That suggests to me that lifepo4 battery packs are a well matured technology, a nearly idiot proof product that requires just basic safety checks.
Basically what my assessment was when I took apart the muscle grid battery:
To be fair, even that musclegrid battery would’ve easily lasted a decade or more in the condition it was shipped. It would take months/years for it give you full capacity, but it would’ve worked just fine, way better than any lead acid battery.
So it doesn’t really matter what branded/unbranded battery you get, it’ll become obsolete before becoming unusable (like DDR3 systems today, you can still use them, but no one’s going to intentionally want to buy/build a brand new one).
This mirrors what I’ve seen on Amazon as well. There’s a lot of unknown brands selling inverters with built-in lithium cells and they have really high customer ratings. Like 100+ reviews that are 4.5 stars, you can’t buy that kind of feedback.
Torque Energy does have the reputation of the company it was before it was rebranded, so you do get a better support/service network, that’s something that the unknown brands on Amazon wouldn’t have.
