DCH 523450 Battery 3.7v 1000mah Rechargeable LI-PO Battery with JST Connector for Household Appliances

This battery was a perfect fit for my device and worked exactly as expected. The size was spot on, and the connector matched without any issues. It charged quickly and held a solid charge through repeated use. I’ve gone through several charge cycles already and it’s still performing great. It feels well made and dependable. If you need a small Li-Po battery for a project or replacement, this one is a great choice.

battery works great and charges fine. the JST connector was bigger than the one that I needed. I had to solder the old connector to the new battery. I will have to read the description better in the future and measure the connector.

I tested the wires with my voltage multi-meter. Seemed to be fully charged. I just have to solder the ends to my old headphones to make a connection so I can charge it and listen to music.

I used this battery to replace the one in the Rexing dash cam, I wish Rexing would make their stuff with user replaceable batteries, but its not so bad, if your a technician, it should not be hard to do.

The size is the same as my last one. It for nicely with the Brant new connection and seems to last as long as the old one.

Product received was at 0v. Unable to charge.

Was working on a small electronics project using an ESP-32 with an on-board BMS chip and two pin JST socket for a 1S LiPo battery. This fit the bill for keeping the board alive during relatively short power interruptions. Hooked it up, and the dev board was perfectly happy to run off of it, and charged it properly. I haven't done any real world capacity testing on it yet, but it ran for a solid half hour or more just blinking the status LED on the dev board on a 50% duty cycle, so more than adequate for my needs.

Purchased this to hook up a WISBLOCK board for meshtastic. I don't know if the wisblock base board has the polarity on the JST connector backwards, or if these batteries do, but when I hooked it up, it fried the wisblock, as the polarity was reversed. I cut the connector off and reversed the wiring, and it worked on our other units with no problem. The issue was probably my fault, so I cannot deduct a star for that. But the battery holds a great charge, and powers my devices just as I expected!
