HXJNLDC DC 3.7V 5000mAh 755590 li-ion Lithium Ion Polymer Battery Replacement for DIY 3.7-5V Electronic Products with Built-in 2-Wire Battery Replacement, Mobile Energy Storage Power Supply

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

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.

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!

Charges and holds charge. Nice steady current

This battery was very hard to find so I was glad to see it on Amazon after a long search. The order arrived and was as promised but the plastic connector was not the one I needed for my security system wall unit. The connector was hard to see on the sale display and I anticipated having to send it back until a relative nicely exchanged the one from the dead batter to the new one and it works just fine, hooray. I suggest the vendor enlarge the photo size of the connector, or provide connector options and battery dimensions on the ad.

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.

Ottimo proprio quello che cercavo

Déjà installé fonctionne très bien, matériel à acheter en toute confiance

Used to replace a swollen battery on my Malahit DSP2 SDR radio. Works well.

After replacing the power connector for a smaller, same type. The battery charged nicely, and the Nano VNA is working well.

Sehr gute qualität
