4PCS 3.7V 220mAh Lithium Battery + 4 in 1 Balance Charger for E010 E010C E011 E011C E013 GoolRC T36 NINHUI NH010 F36 H36 HS210 SANROCK GD65A ATOYX AT-66 Quadcopter RC Helicopter Battery Accessories

I picked up these batteries to use in a handheld synthesizer that accepted one but did not include one. Sadly, the dimensions were slightly off and they didn't fit in the available space. No matter, I'll find a use for them in another project. They seem to be of similar quality to other LiPo batteries I've salvaged from various devices over the years. And the multi-port charger will come in handy. If you know they'll fit your needs, I give them a full recommendation.

The charger seems to charge and work as intended. It is a little finicky sometimes but it works. The issue for me was that of the four batteries, only one of them seems to hold a charge. I get around five minutes of flying from one of the batteries and with the other three I’m able to take off, hover for a few seconds and then the drone descends slowly and lands itself due to no battery life. Disappointed in my purchase. The drone I’m using them with is the Makerfire mini FPV drone, the blue shark one.

Tough to say much about Lipo batteries. These fit what I needed them for and seem to work and charge well. They come with their own charger but I use one that I’ve had for many years flying helicopters. These fit the bill for me and they all work. Recommended.
