- Bulk/absorb: 14.2 – 14.6 V
- Float: 13.6 V or lower
- No equalization (or set it to 14.4 V)
- No temperature compensation
- Absorption time: is 30 minutes per battery (if it’s an option)
Any lithium battery has a battery management circuit to control the individual cells. This circuitry will prevent the batteries from being charged when any of the individual cells are below 32.2 degrees F.
The other problem is using the engine's alternator to charge the lithium battery. Lithium batteries have virtually no electrical resistance and if hooked directly to the alternator can cause the alternator to overheat and fail. It is recommended you install a DC to DC converter in the circuit to regulate the current going to the lithium battery. |
I have 2 100 amh Duracell ultra's. They charge up to 13.4 to 14 and then gen starts within an hour and the amperage is down to 12. I am starting to believe the batteries are worn after only 1 year old. this is with running just the led lights , and the propane heater blower. I played with turning on the fridge (residental) and it cooled down fine but the generator ran for almost an hour to recharge the 2 house batteries before shutting off. Then started again in an hour??
My first call tomorrow is the Batter store on the warrantee ??
