Radiolink 7.4V 2S LiPo Battery 5C 1700mAH JST 2Pin Connector for RC Car, Airplane, RC Transmitter Like RC4GS V3/RC6GS V3/RC8X/AT10II/AT9S Pro/T8FB

Works great i have it in my radiolink controller battery last days on a single charge , very easy to recharge i got a balance adapter and charge it as a 2s on my charger i highly recommend it beats batteries

Works great better than aa batteries, it doesn't come with a charger so you will have to have an adapter to charge

Easy to replace the old battery box, fits right in the controller. Has a long battery life I’ve only had to charge mine one time in the last 4 months. Worth the price and better than wasting AA batteries.

Great product at a good price and Fast shipping.

This is a good battery

Charged once but then three months later when I needed to charge it again it will not charge. The little charger that comes with it just brings up one red light and stays that way indefinitely regardless of what charge cable I hook it up to. Unfortunately, they tell me it is out of any support or warranty window.

Perfect fit thanks will buy again

I'm thinking about buying another but the first one lasted 5 months. I like the idea of this battery a lot so I gave it 3 stars, and perhaps it's the radio that is the problem.I've run this battery down to the alarm 3 times and accidentally killed it today. If the radio had an on off switch that would stay off, perhaps this battery would last longer. My on off switch has a hair trigger, and can be turned on with just the slightest pressure. Like brush it against your pant leg lightly and you could switch it on. So anyway I'm back to AA batteries.
