850mAh 25C 2S 7.4v Lipo Battery Pack with JST Plug for FPV Racing (2Packs)

Excellent quality and performance. The wire gauge is thick for less current loss and heat build up. The batteries are well worth the price.

The hold a charge nicely I bought them to fit in my transmitters for RC trucks.....They were a little bigger than I'd hoped from the measurements they provided but a little customizing on the transmitters and its like they were made for it!

I got these SYPOM batteries to use in either a drone or a beetleweight battlebot. I'm still in the design phase for the battlebot and in the process of ordering parts for the drone, so I haven't been able to use these to their full abilities yet.They look to be high quality with nice silicon wiring on both the balance wires and the main power leads. I'm a little confused why these ship with deans plugs instead of something like an XT-60, which is what I will be changing them to.The batteries came at storage charge in little blister packs, no complaints from me. These appear to be good value, and as long as they hold up I'll be using them for quite some time.

Charged up fast and like getting two

Nothing to complain about here. Everything seems in order. The battery leads are of decent gauge. The Dean plug comes pre-installed which is always a bonus. Battery life is as expected and comparable to our other batteries. So far so good but like many of these types of products, it's all about how they hold up in the long run. I'll be sure to report back if they turn belly up prematurely.

These work well for receiver packs in gas powered R/C as well as in my profile biplane. Small, lightweight and after a couple cycles I'm getting full rated capacity out of them easily. The connectors mate well to my actual Deans brand connectors. The wire used is good quality and so far, these seem to be a fantastic value.

This arrived at about a 45% charge. It took 423 mAh of energy to charge it to 100%. That's within 10% of the rated capacity, which is what I've seen with other batteries. Batteries have pre-installed Deans connector and a standard balance connector.

These seem to be some good solid lipo batteries. They charge nicely (no glitches) on my hobby charger. I used them in an RC truck that came with a 1000mAh battery and these performed very well. Plenty of power. No lag at all. Wouldn’t hesitate to recommend these!
