How can you use a 12v LiFePO4 with the CHG connection on the Charger 2? I know it is setup for a power station. How can a battery (bank) be tied in?
I don’t think you can “directly”. The Bluetti Charger 2 expects the battery characteristics/charging profile of a lead acid battery, which has a different curve than lithium/lifepo4 batteries. Perhaps you can do so if you find an additional dc-to-dc charger (or a charger controller) that can mimic that type of voltage output. If you try wiring directly from bank to CHG port on Charger 2 it should fail.
My last install was using a etaker F2000 that allowed charging a power station or a LiFePO4 from the same port. Can anyone from Bluetti please expand on why the Charger 2 can / cannot work with a 12v LiFePO4 battery / bank?
Does the app allow you to set the charging profile of the CHG connection thus turning it into a charge controller?
