YDL 3.7V 350mAh 802025 Lipo Battery Rechargeable Lithium Polymer ion Battery Pack with PH2.0mm JST Connector

I purchased this to replace the tiny battery in my Ring Pro Doorbell. It system stopped working when the battery did so I looked around and found this one. Its a near perfect match as far as dimensions go. I did have to take the board off the top of the cell and re-connect to the original batteries board but once done the Ring was back in service!

My dash can battery died and this one is working great. I had to solder the wires to old cam.

Even though this battery has the same designation (802025) and it claims to have more energy (350mah vs 300mah for the old battery) these batteries hold very little charge. Maybe 10% as much. I thought the first one was bad so ordered a replacement but it has the same issue. Must be this company. One to avoid in the future.

good value

I had purchased this to replace a bad battery in a small drone toy. I found out afterward that this is a low current battery pack (probably 1C), and would only be good for electronic devices that have low current needs. It powered up the drone just fine, but as soon as throttle was increased, the battery shuts off, and requires a charger reset to work again. Unfortunately, the current rating is not shown on the listing, so I will chalk it up to "live and learn". Just writing this for anyone else that may purchase for same purpose I did, you will need a much higher current rated battery (20C or 25C is typical).

This battery only delivers about 0.1 amps. It is not powerful enough for my intended use. If the amp rating had been included in the Amazon listing, I would have known not to buy it.

its nice and it fits to my drone I also need the charger to go with this

It worked awesome replacing my battery for my dash cam Vantrue N2 Pro.
