elxjarpower (4-Pack) 11.1V 2000mAh Li-Po Rechargeable Battery with SM2P Plug & USB Cable, Compatible with WPL RES V-3 ESC 1/16 RC Crawler, 501855 Soft-Gun & Water-Gun Toys

Great small sized 3s batteries for my smaller RC needs. I have tested them and the battery life is good, and the connections work wells solid value pack of batteries.

My husband has a bunch of RC 1/16 scale vehicles that have been sitting around collecting dust, but now that our son has shown some interest in them, we have been getting them up and running, and most needed batteries. This 4 pack of batteries seemed like a good value, and were cheaper than buying at our local hobby shop, but are much smaller and lighter than the ones we are replacing. I can’t see how they are the same capacity as the old ones. That said, the ones we put in the crawler worked fine for now. I can’t speak to battery life yet, but will update this review when I can.

Why did you pick this product vs others?: I used these 11.1V 2000mAh Li-ion batteries in my small scale RC truck, and they’re decent for the price. The batteries provide a reasonable run time, lasting long enough for a good session of driving before needing a recharge. The charge time via the included USB cable is acceptable, though not particularly fast. The SM2P plug connected easily to my RC car without any issues, and the build quality feels solid enough for regular use. My only minor complaint is that the run time could be a bit longer for more extended play. Overall, these are a reliable choice for powering smaller rc toys.

These seemed pretty lightweight for their capacity, and when I got them, they're considerably smaller, too. Lighter even than some 750mAh 2S batteries I had handy. So I discharged one to 3.2V, charged up to 4.2V at 500mA, and it came up just shy of 350mAh. So that's quite a bit less battery than what is stated. Not that it's a bad battery, just certainly not as advertised, even with the capacity of all four added together.

These are great batteries for WPL Trucks! 3S and advertised at 2000 mah (although I question if these are above 1500). Gives good power, good runtime, fits in the B and C series WPLs. This beats the heck out of the 2Ls that come with the standard and KM/transmitter kits. I do not know if they will work with the D or E series WPLs. I don’t have much more to say other than you’ll never go back to 2S batteries after trying these. I totally endorse these for your 1/16 trucks. But wait! There’s more! These fit into the 1/18 TRX4Ms also! Mine has a 1060 ESC and easily takes the 3S. I don’t know if the stock TRX4M RTR electronics will take a 3S, so do your research before you plunk down the money for these. I did have to change the connector to match the XT60 for my project TRX4M, easy peasy but cut one wire at a time.

these little batteries work well and battery life is as expected. I was able to fit these in my 1:16 scale cars.

Nice little lipo's that include two USB chargers however, I don't think that these are 2,000mAh given their size also one of the four packs I received has the third cell in the pack at 0.00V

These LiPo batteries are a good value and do hit their advertised voltage, which is great for budget builds. However, it’s pretty clear that the claimed capacity is overstated—the size alone suggests they hold less power than advertised. For light use or low-drain setups, they’re still usable and decent. But for more demanding applications, you’ll probably need something else as these won't last. A fair product if you manage expectations. 3 stars
