I would like to ask if this battery is usable.

I have successfully turned on the TX2.
I read that the specification says the rated power is 5.5VDC: 14.5A ~ 19.6VDC: 4.74A. I would like to ask if using this battery will cause damage to the TX2. ?
Thank you!
Hello,I would like to ask whether this current of this battery is ok? And how long can it power the TX2 with this specification?
The voltage level is safe and the real current consumption depends on the use case running on TX2. You should measure the power consumption and calculate the working time.
