While everyone laughs at him for asking about car battery. I actually use a very similar style battery in my car and it works perfectly fine. But it's a mini battery kit. Probably not the best for a regular person

I know starting a car might be asking too much from this battery but does any one knows if it would be able to start a riding lawn mower.

I don't know how these batteries don't have an internal temperature sensor. These should not be charged in freezing temperatures.

This is a bummer as I just bought a 50aH from this same company. I made an assumption that all LiFePo4 cells have this at minimum from the BMS.

Would this work to replace a small generator starter battery? The starter battery kn my predator 3500 went out a while ago

Probably, as long as it can fit in the tray where it needs to sit and you don't need to use it in freezing weather it'll probably work.
Otherwise you might be better getting that 12V AGM battery that HB offers and just keeping it connected to a battery tender when you're not using the generator.

Probably not, it only has a 30 amp BMS. From a quick Google, many mowers require 100a or so.. You could try looking up your mowers starting amps, but I'd guess it will trip the BMS.

Where do you see it has 30A BMS? Did they upgrade it as it is only listed 20A on the page? 30A BMS would work to start a small generator.

No. Not a high cranking amp battery. There are specific high cranking amp batteries for starting things like riding mowers, and larger ones for cars. They are more expensive than these. I bought this LifePo4 riding mower starter battery and it is only 10AH, but 700CCA: https://www.amazon.com/dp/B0CNT6XCG4 . It cranks the mower hard (good). The battery in this post is limited to 20 amps, not 700 amps.
