In this mode, you can quickly adjust the output voltage and current. The module remembers your last set values upon power cycling, but advanced automation settings are hidden. Mode 1: Full Function Mode

The BST900W features a user-friendly front panel with 4 buttons, a bright red LED screen, and three status LEDs.

From the idle home screen, press the UP or DOWN arrows to cycle through stored parameters ( M-0 to M-9 ). Press OK to load the selected configuration profile. Applications and Use Cases 1. DIY Electric Bike (E-Bike) Charger OK: Confirms settings or toggles the output ON/OFF

This section covers the core programming functionalities.

Do not exceed 15A on the input side. If your source is 12V, your maximum theoretical power is 180W (12V x 15A), regardless of the 900W rating.
