LiPo Battery Testing Report About Gens Ace Lipo

Lithium polymer (LiPo) battery cells are more and more popular and are used extensively in remote control models, particularly airplanes. LiPo cells produce 3.7 volts and have a capacity of 2,100 mAh (milliamp hours), if in good condition, which is approximately three times more than a nickel-based rechargeable battery. If you want to test the condition of your LiPo battery pack then use a multimeter and you can test the voltage and mAh. Recently I bought two pack gens ace lipo batteries from genstattu, one is 5000mah 3s lipo battery, the ohter is 2200mah 2s lipo battery, all of these two lipo batteries run well now with my RC models.

I have tested many batteries from the cheapest to the most expensive. There are NiMh batteries out there that make some of the LiPo batteries look awful, particularly when it comes to the discharge graph. Some of the cheapest LiPo batteries on the market have a discharge slope that is linear with a negative slope. Most NiMh batteries for the same price offer better performance than a lot of the cheap LiPo batteries, but at the cost of weight.

Like all things, you really get what you pay for. One might argue the fact that their cheap LiPo batteries work great for them and they have no issues. Thats just great, and I am glad you are happy. I'm simply stating the facts.

Some other useful info about LiPo batteries:

1. After a discharge, the cell voltages of a pack will rise back up and try to get as close to the nominal voltage as possible (3.7V/Cell).

2. LiPo batteries should not be charged more than 4.25V/Cell, and should not be discharged more than 2.75V/Cell.

3. LiPo batteries should be stored at room temperature. For prolonged storage, keep the battery at a 40% charge level.

4. If your lithium battery has swelled, toss it. There has been a phase change in at least one of the cells and it is permanently damaged.

The following is the Gens Ace 30C Lipo battery testing report

3S 7.4V 5000 mAh Gens Ace 30C LiPo Battery Tests

The 5000mah 3s lipo LiPo batteries are compact batteries often utilized in small scale flying radio controlled models such as RC planes and helicopters. These small batteries have a pretty high discharge and charge ratings that we need to confirm in our tests. What is important to note for this particular battery is that it can be a 2 cell battery, but there's no balance plug, only a JST discharge one that brings out the combined voltage from the two cells. While this normally should not be a serious problem, not having a balance connector may shorten the life of the battery if the cells become a little more and more disbalanced over time.

For comparision here is the data for the Turnigy 2200mah 35C battery.

Scenario (Turnigy) ........ IR(mOhm) ........Amps(avg) ........ C(avg)
Full Charge (75F) ................... 3.5..................... 61 .................... 28
Full Charge (95F) ................... 2.2 ....................71 ..................... 35
Storage Charge (75F) .......... 3.4 ................... 62 ..................... 28

We can conclude that the 3S 7.4V 5000 mAh Gens Ace 30C LiPo batteries are performing very good and meet their specs, the only thing to note is that if you are going to be pushing to their maximum you should make sure they are cooled properly (at 25C-30C discharge rates). a lot of different 3s, 5s, 6s and 10s in different sizes on sale now,welcom to buy lipo battery for your rc model from genstattu now.
