Petition for battery testing standards!

[brushlessboy16]

This is a petition that when completed will be sent to battery manufacturers to see if they would be willing to conform so we can get at least something close to actual, comparable data... I call it the BW Rating system.

Lipo battery capacity guidelines

- This test should start with a battery or cell discharged to 3.0 volts per cels (+/- .02v)
- Using a lipo friendly(cc/cv) charger with either a built in capacity readout or using a device such as a watt meter to monitor input into the battery.
- The final product- measured in milliamps is produced when the pack or cell have peak charged to 4.20 volts per cell.

Constant Amperage testing guidelines-
-To be performed at a predetermined temperature

-The constant amp rating is the rating at which a cell or battery can hold no less than 3.5 volts per cell under load, OR not change in external temperature by more then 40 degrees Fahrenheit during the duration of the test- Which ever comes first.

- If the temperature cutoff cuts the test short, amperage should be reduced to such a point whereas the cells do not exceed maximum testing temperature. this amperage is your constant amperage rating



Burst Amperage testing guidelines-
-Test to be performed at a Pre determined temperature

-The burst amperage rating at which a cell can sustain 3.2 volts per cell under extreme load for 10 seconds OR without seeing an external temperature increase of 30 degrees farenheit- Which ever comes first.

- In the event that a cell or battery test is cut short by maximum temperature cutoff, the amperage should be reduced to a point where the pack/cells do not exceed maximum temperature cutoff- this amperage is your burst amperage rating



All amperages then can be converted to actual C ratings using the formula
A / aH=C

If you felt that this testing method would improve the quality of the hobby please submit your vote and post your name and a "yes" or "no" in this thread
