3. Operating Instructions
Once connected and charged, the KAB-BE board provides power to your KAB amplifier board, enabling portable audio applications.
- The voltage balancing feature ensures consistent power delivery and prolonged listening times by managing the discharge rates of individual batteries.
- Multiple KAB-BE boards can be sequenced together to further extend operating time. Refer to the KAB amplifier board documentation for specific instructions on daisy-chaining battery boards.
4. Maintenance
The KAB-BE board is designed for low maintenance. The built-in under/over voltage protection circuits contribute to battery longevity by preventing common issues associated with Li-Ion battery usage.
- Regularly inspect the board and connections for any signs of damage or wear.
- Ensure batteries are properly seated in their slots.
- Store the board in a dry, temperate environment when not in use.
5. Troubleshooting
If you encounter issues with your KAB-BE board, refer to the following common troubleshooting tip:
Amplifier Board Not Powering Up After Battery Removal/Reinsertion:
If you remove and then reinsert batteries into the KAB-BE, the connected amplifier board may not power up immediately. To resolve this:
- Connect the 19 VDC charging adapter to the KAB-BE board momentarily. This will reset the protection circuit and allow the amplifier board to power on.
