7.4V 1000mAh Li-ion Battery - 2 Pack 2S 30C Batteries with T Plug for RC Truck Brushless Racing Car HBX 16889 16890A and XLH Q901 Q902 Q903 1/16 Scale with Rechargeable 2 USB Chargers

Great Choice! I have had ZerO issues with this product! For the money you canNOT beat it!

Works perfectly. Just charge it up then unplug from outlet. Hook the red and black cables to your battery, then let sat for a few minutes and then it will start. Remember to take off red cable first. It fits nicely in my door pouch. It has given me peace of mind. Buy it now so you have it for future use.

Worked great for my son's RC truck. Actually better than the original battery.

The batteries themselves seem quality, but: - The length is nowhere close to 51 mm as stated; probably, the cells alone are, but full assembly is rather 55..56 mm. - The chargers are useless, being bloody slow. For who knows the electronics, it's not that easy to design a balancing charger for 2-cell battery running off the 5V USB. Hence they did a trick - charging alternatively each cell for 1 sec, then switching. This doubles charging time, on top of already slower rate due to USB current limitations. Didn't clock it (went straight to a hobby-grade RC battery charger), but my best guess is 3.5..4 hrs if USB source is capable of 1.0+ A.

Good product.

Work perfectly on the amphibious vehicle I got for my girls.

The batteries are a perfect fit for rc truck

Got one of those 4x4 drift trucks. Things a ton of fun so I wanted to get some more batteries just to be extra. They seem to function just as good as the batteries and come with it I mean they probably come out of the same factory it's not like we can talk trash on them because they're from China because the whole things from China
