another fire risk
This is all pretty new to me. Is the fire risk from overcharging? Is that because the bms doesn't work?

Mine felt light so I tested the capacity. I'm getting 99AH. Seems to work fine but I haven't used it much.

The markdown from $1210 is your first warning sign. I'm happy buying the ecoworthy batteries on eBay when on sale.

LiFePo4 is very safe compared to other battery chemistry - watch this video.

Is "MFUZOP" the sound that it makes when the battery shorts out?

LiFePo4 itself is, but there is more to these than simply the chemistry type. While I don't agree with needing UL ratings for a lot of things, for cheap and generic LiFePO4 packs setup just about anywhere, I'd look for legitimate UL1973 certification to ensure the rest of the pack is built safely.

Or when Hanson tries to sing their hit single, but their dentures loosen up.

At least the seller seems ok but has only been around since January.
You have to watch these guys. I have a shipment coming from another seller that said shipping from the US and it was clearly imported as it had to clear customs. They also swapped shippers as it said USPS at purchase but now it reads UNIUNI (a 3rd rate scamy shipper).

Do your homework with Alli, especially on pricey items where the scammers tend to come out to play. I'd be hesitant where it says "Seller shipping" on this. Illegitimate shipping methods are a go to play for the old failure to deliver with received tracking scam.
