60 amps or less after 10 secs of charging is to check the charging function.
Is to be done when the batteries are charged, and if the amps are still above 60 amps after 10 secs have passed what is faulty is the charging function, not the battery. The battery is at full charge but the charging function keeps sending current, and that will be a source of fire in flight.
If the batteries are below full capacity, then you have to make a charging cycle of 20 minutes and test the BLC's again.
Somebody please correct me if I am wrong.
Now let me throw another question: is there any defined voltage at which a charging cycle should not be attempted and a battery change is required? Is it written anywhere? How to know if 10 V is good enough to attemp a recharge with GPU?
Much obliged!
