This is normal behavior if charging a dead battery. If unexpected, increase your current limit parameter or reduce the load.

The BST900W is a high-power, step-up (boost) DC-DC power supply module featuring digital control and a four-digit LED display. It is widely used by electronics hobbyists and technicians to step up lower input voltages to higher output levels for driving high-power LEDs, charging batteries, or powering experimental circuits. bst900w manual

When configuring your Voltage (U) and Current (I) via the SET menu, press SET a third time. The screen will display 00.0- (where the first digit is the memory address). Use the arrows to pick a slot (0–9) and press OK to save.

Understanding the operational limits of the BST900W is critical to preventing thermal runaway or permanent component damage. 8V to 60V DC Input Current Limit: 0A to 15A maximum
