HOOVO 2200mah 50c 3s,4s Lipo Batteries from Amazon, After Extensive Testing, Results

From 50% Storage charge, they only took about 730mah to full charge. Should be 1100+ on a 2200mah 3s lipo. Not just one battery, ALL 4 ,3s and 4s all only took same and only gave almost as much to drain back to 3.84/cell. These are more like 1800mah 30c than 2200mah 50c...!!!
SENT THEM BACK. Sale Price or Not.
Only got 2 mins. of flight with a Timber bringing voltages down to 3.69/ cell. Then only took 1550mah to full charge. All 4 batteries ????
Shame, Nice looking batteries and well packaged. Just way short on capacity.

UPDATE......Here is the reply from Hoovo I got back after a week. They think I don't know what I'm doing...
Give me your opinion.

Dear Skip Mette,

I'm sorry for not replying to your email in a timely manner. Thank you very much for purchasing Hoovo batteries and providing feedback on their use. Regarding the battery capacity testing issue you mentioned, we would like to provide some suggestions and explanations to help you better understand the working principles and testing methods of batteries.

When the battery voltage is between 3.7-3.9V, its voltage tends to stabilize, but the battery capacity is not necessarily 50%. In fact, this error is quite large because the charging and discharging characteristics of batteries are influenced by many factors such as temperature, charging rate, and discharging rate. Therefore, if you want to test the battery capacity more accurately, we suggest that you discharge the battery to 3.0V and then charge it to 4.2V.

In addition, when using batteries, please make sure to charge and discharge them correctly, and do not keep the batteries in high or low temperature environments for a long time, in order to avoid negative effects on the performance and life of the batteries.

We sincerely appreciate your support and trust in our products. If you have any further questions or concerns, please do not hesitate to contact our after-sales team, and we will do our best to solve the problem for you as soon as possible.

Best regards,

Hoovo after-sales team
