Any troubleshooting/ideas are appreciated.
Pack details:
4S4P
Panasonic NCR18650B cells
fully charged and capacity tested to ~95%
low IR
All 20 cells are the same voltage
4S 30A BMS
Testing:
Using buck converter to reduce voltage to 12.8 so I can use a12v 150W inverter, rated for operating voltage of 11-13V
Using Kill-a-Watt on the AC side of the inverter.
Load equals a 60W variable temp soldering iron.
Problem:
Pack will power the inverter, but the inverter shuts down when the load exceeds 20-25W/2A. The pack voltage remains in the acceptable range under load.
It seems that this pack should have no problem powering this load at full (60W).
What am I missing?
