The Problem: My daily drive can be only 10 minutes, which is insufficient to fully recharge the battery pack.
The Solution: Gemini helped designed a "Hybrid Power Path" using a
1N5822 Schottky Diode to bridge the car's main 80Ah AGM battery as a secondary backup.
Wiring Logic:
- The Viofo HK6 B+ line is connected to both the Battery Pack output and the Car's Main Battery (via the diode).
- The LiFePO4 pack (resting @ ~13.1V) will be the primary source.
- Once the LiFePO4 pack is depleted, the diode allows the car's main battery to seamlessly take over the load.
- The HK6 is set to 12.2V to protect the main AGM battery from deep discharge, especially since it's limited to an 80% SOC by Ford's BMS.
Questions:
- Will the 1N5822 (3A rated) handle the constant draw of a 3-CH system without overheating?
- Does the HK6's Bluetooth voltage monitoring handle "source-switching" well, or will it trigger a reboot/error when the voltage shifts from the 13V pack to the 12.5V main battery?
Thanks for the help!
