ALPHAREV 2 x 7.4V 1200mAH Original Batteries R206/R208/R308 RC Boats

The batteries work well but I thought they were junk initially. That is because after fully charging them they would run my RC boat for maybe a minute, then the RC boat controller would start beeping (indicating the battery is low). I went through this cycle of running the boat for short periods then charging the battery a few times, feeling frustrated. Then, I decided to see how much longer I could run after the beeping started before the battery was completely used up. To my surprise, it ran for 10-15 minutes more! The only caveat is the boat lost some speed if I ran it full out for extended periods without a cooldown. These batteries do get very hot and I think that reduces the output temporarily. But the run time is great! Recharging after a long session is a couple of hours for me. I am satisfied and am glad I figured out the beeping can be ignored, the battery is fine.

Batteries must be cycled a few times, then they will give you solid run time

These don’t fit in the battery area, but I could lay them flat in the middle. Fits and works great. Longer life than the 600.

Works great with my husbands rc boat . They hold charge and makes it easier to enjoy play time :)

Easy to charge and battery run time is as advertised.

Fit and worked great!!

Bought as a Christmas present but didn't take out to use until last week. One battery does great and the other won't take a charge. Because we waited until summer to put in the water the warranty/return window has expired. Anything we can do?
