I'm having the same issue as the person in this old thread.
Bought the BW25887EVM. Using a 2SP1 battery pack and using a bench power supply running at 5.00v / 3.00A Max. The eval board is pulling 2.5A from the power supply but the charge current is only 1.5A. I have JP4 tied to GNDand JP2 floating with TP21 tied to GND (ILIM tied to GND).
Ideally I want to get the rated 2.2A in standalone mode. How can I achieve this?
Below is a register dump.
