it still has to ramp up to max current so its time numbers are not actually true to test .
anyone looking for real comparable numbers will use a hard load discharge.
the first 150sec is the most important #s a pack has to offer.

There are so many youtubers doing this sort of test with 40amp dischargers, that they save me trouble... It seems that the newer the pack, the better the results, and the good brands always have close performance: Fantom, Arrowmax, IP, Turnigy, etc,.....

Discharge load + this:

It will log the voltage curve and display with this software

You can also just take readings from the screen during the discharge by hand.It will also run in line with a turbo30/gfx/whatever. With a auto relay, you can use the internal alarm wiring to stop the discharge by voltage, time, capacity total watts, etc.
