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

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.

I haven't done a discharge test to verify its 1000mah claim, but the battery size is what you'd expect for a 1000mah battery.The JST polarity matched other LiPo batteries I've got in projects, so it was a drop-in replacement for them. That said, there's no real "standard" for JST connections on these, so make sure its right before you plug it in. You don't want to fry your electronics... or worse, reverse charge the cell.A good deal for a battery with quick Amazon shipping.

This LiPo 1000mAh battery, size 523450, is 53L x 34W x 5T mm and comes with a 2mm pitch 2 pin JST connector. I used a 03962A 1S LiPo charger board to charge the battery and a constant current load tester to measure the battery’s capacity. The measured capacity of the battery was almost exactly 1000mAh when using a 250mA load. I cycled the battery a few times between charge and discharged without any problems. It is performing as I expected and works great with my project.

I decided to try this battery to replace a 3.6 V Ni-Mh battery for a Vtech cordless phone. I had to replace the connector with one from the old battery. It works fine and should last a little longer between charges. It's thinner and lighter but not enough to really make a difference.
