Lipo 4S Battery,14.8v 3300mAh Lipo Battery Pack 50C with T Plug for RC Helicopter Airplane Boat Quadcopter (2 Packs)

think of these as really heavy like 100 grams heavier than your regular 2200 mah 4s 50c that cost's $25. They are not worthless i use them occasionally on my drone and lug them around as charging batteries with my portable charger so it's not all bad. But in a sense sort of a waste as well. I suggest selecting some other brand to be honest.EDIT: I was originally disappointed in these batteries. But as others said cycle them 6 times or so, and they do come up to full MAH discharge charge rate. I use them in a 7" drone that has 4s-6s motors so these are low power and lower on the c rating so as far as performance go i can't say since they are at the bottom end but they do fully charge discharge their 3300 MAH rating which i was not getting earlier. I used these as my "Trainer" batteries so to speak and for that they have been fantastic.

On time and in great condition thanks

Extended flight times

This is my 3rd pair of batteries. 4s-3300MAH LIPO I use them in a trainer plane with LOTS of cycles. Just retired my oldest battery, was purchased in 2019 Love them

So far so good. to early to tel. They are a little heavy for 3330 6 cells but they fly my EDF jets. Had about 12 flights so far on my to pack holding steady flying e flight f 16, fms f 18 and fms f 16 . can pull the necessary amps .come back warm but not hot- cell holding up so far.

Very good battery

Capacity not as advertised. I bought these at the same time as HRB 3300. In use these are providing 1/2 of the HRB. RC plane alarm goes off at 3 minutes as opposed to HRB 3300 6 minutes. You can see in the pics that the HRB is over 1576 and still charging. while the Youme battery has stopped at 1182 mah. I tried this on a few different chargers. As you can see the Youme batteries are sub par to the HRB. I truly wanted these to be good at a cheaper price. Thank you Amazon for the awesome return policy when a product is not as advertised. I tried cycling them a few times to see if the capacity would increase, but still the same.

The media could not be loaded. Purchased these batteries to try them out on my 56’ 3D plane. I got a chance to fly them today. They come in lighter than my Turnigy 4s 3300 30C. They were perfectly balanced out of the package (.01 difference per cell). They have the power I needed. I added short video of the flight.
