Battery works as intended for Raspberry Pi
Works for a Raspberry Pi 5 great. Last a few hours running multiple websites and constant running. Would recommend.

Specs exactly as described, don't forget safety though
Bought these to power 700 LEDs in a pair of pants. Lasts about 35 minutes running a light show (which is what we calculated so that's fine).Main thing to be mindful of is that this has no type of covering at all, so we had an issue where we didn't build an enclosure for it and it got scratched and started smoking, so we had to safely dispose of it.Safety first! Make sure you have a suitable enclosure!

The battery arived as promised.
This battery was a replacement for a solar charging unit that I use i a car. The old one 'expired' and grew fatter. Time will tell how well the new one will take and hold charge.

Let there be light.
It doesn’t have enough power to start my car so I’m thankful I didn’t buy this battery for that. (My car came with a battery that has lasted a while.) I bought this battery to power other things and it works great for that.
