FEILUN Test Qualified 700mAh 3.7V High Power Rechargeable Li-ion Battery Pack for Remote Control High Speed Racing Boat RC Vehicle Cars Truck Airplane Helicopter

Needed extra batteries for remote control boat these fit and work very well. Seem to recharge and hold charge well. Would purchase again.

I have 2 of these batteries, one doesn’t preform like the other. I have put them on my smart charger for my other R/C vehicles, but it will not come up to the advertised 700 mah, advertised. The other makes the little boat I bought it for, almost to fast for my pool. I figured these should both preform the same. Sadly, I missed my window to return or exchange. Should you purchase these batteries, do not settle for them if they do not preform correctly, exchange them until you have 2 that operate the same.

I purchased 2 of these to replace the ones in my boats. After trying both of these I figured my boats were busted because neither boats worked with these new batteries. I made the mistake of throwing out the old boats and buying brand new ones (same TR800 models). I got the new boats and these batteries still don’t work. I’ve tried charging them overnight and still no luck. I can see receiving one bad battery, but not both!

My brother-in-law love his new boat and this will help him love it more

Works like it is supposed to.

Good product

It's just an extra battery works good
