Lithium lifepo 100 amp batteries?

[MrGiggles]

I'd be most worried about the cheap batteries from Amazon/ebay. Any other no-name chinese electronic on there is pretty much guaranteed to be garbage, the BMS in those batteries is likely to be no different.

Anytime a company emerges, and is selling something warranted for 11 years......If you think that company will still be around in 11 years you are dillusional.   

They'll make all their money in the first 4-6 years......then they'll be GONE.  

There won't even be a soul to answer a phone there when the integrity of that cell is in question.    So the name that you trust today isn't any better than a name off of Amazon.

There are plenty of videos on Youtube of guys taking the different battery brands apart and comparing them. Most of them are the exact same thing with rebadged cases.

I’ll ask Todd at Project Farm to do a deep dive on them.

Plenty of "deep dives" have been done, since they are great for cordless tools and cell phones.  But once you get into bigger stuff like golf carts, trolling motors, and (god forbid) full size cars & trucks.... I think you cross the line on what is actually safe & smart. 

Some things look great on paper, but in the real world of hillbillies and Rube Goldberg types...... you're just begging for trouble.

Large voltage capacity lithium cells are kinda in the same category as dynamite, mortar shells, and other things that you can't just pick up at the local Farm & Home.   I mean wasn't a Lithium power cell (thermal runaway) at least partially responsible for the Challenger space shuttle catastrophe? They can't (or shouldn't) just be used without constant monitoring and proper control.  And even with constant monitoring and proper control......things can go bad wrong.

Well I'd say that you're smarter than the guy that designed it....... but then you DID buy the freakin' thing.  🙄

Love it too.  41 mpg.  Drove it the SC and back for under $150.  About 2000 miles.
