Gens ace7.4V 450mAh 2S LiPo Battery Pack 25C/50C with JST Plug for Emax Babyhawk RC Heli 250 Helicopter Small Airplane Micro FPV Racing Drone Quadcopter

Work great for what I need them for, bought 2.I bought a JST to PH 2-pin adapter to make it work. I used this one: https://www.amazon.com/gp/product/B07RMXFBXH/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1This solves 2 problems IMO. 1) It makes it so you don't have to continually plug & unplug directly into the ESC (which down the road will cause that connector to wear out). 2) This battery is much better than the stock one.

I bought this to power the flight computer for my Loc Precision LOC-IV X2.

For someone like me that isn’t meticulous about keeping my lipos at storage voltage or keeping in an optimum storage temp when not in use, these have been far better than other big name batteries as far as staying able to take a charge, NOT PUFFING UP, and withstanding a lot of cycles. Not recommending leaving them in a hot car or fully charged for weeks but these have taken such abuse well when all others dont.

It's exactly as I thought. Small and powerful for my purposes.

Perfect size I was looking for my rock crawler

with my small 1/16 custom car i get about 2 hours of battery life and 20 min charge note that the car is going about 2 mph. just make sure you get a good quality charger and lipo fire bag

These packs are great. They give me plenty of flight time and I do not feel any sag at all all the way to the end of my flight timer. I already have many cycles on these batteries and they have broken in well and are very consistent from pack to pack.

Great little battery to avoid going through AA's like crazy in my rc transmitter, it fits perfectly and even though it is only 450mah I seem to get more time on a charge than a full set of new AA batteries on my power hungry digital transmitter.
