7.4V Li-ion Battery 3300mAh High Capacity RC Battery with Dean-Style T Plug 2S Rechargeable with 1 to 2 USB Charger Fit for WLtoys 4WD High Speed RC Cars Most 1/10, 1/12, 1/16 Truck

So far so good. Came with a double charger. Good battery life, great value, way better power that stock. They are slightly larger than the original but still fit with a little help.

Perfect fit. Works great. Easy to charge, lasts a long time, about 30 mins of playtime in out RC. Would recommend buying!!

Charges fairly fast.Last longer that other batteries I have tried

You charge them up put them in your RC car and RC car goes it's pretty awesome how it works like that. It's a rechargeable battery man they have a good life they last a long time you know honestly they're good quality battery and it's a good value for the money I'd buy them again

I recently got a 1/10 RC truck from a friend and it came with one battery that ran about 10min. I took some measurements and found that these were an exact fit (however this looks like two 18650 batteries side by side versus the factory battery) with the same voltage. After charging them up I got about 25min of run time which, accounting for the OEM battery being 5yrs old, seems about double. So with two of them and the factory battery I can now run for about an hour depending on other factors. The included charger got these charged up and the correct plug style meant these were plug and play, just what I needed.

These "3300" mah batteries didn't last any longer than the 1500 mah batteries the car came with. And you only get full speed for about 10 mins and then the RC car will go half speed for another 10 mins before the batteries die. Nothing special about these and I question if they are actually 3300 mah.

worked good for my purpose which was to power a parrot skycontroller2. 7.4v vontroller which i spliced in the old packs wiring harness. cannot charge in controller but the one it vomes with works or even better get a hobby aftermarket charger.

Wow what an upgrade,each one lasts more than 35 minutes run time at about 80 to 95 percent throttle great batteries
