Merry Christmas, Happy New Year, and Hallelujah! I'm done!
Finally got my crimpers and plugs and got the battery monitor going. Unhooked the last 2 lead acid batteries and hooked up the LiFePO4s. Turned on the system and I'm running on Lithiums.
Took a bit of figuring to set my old Freedom 2500 inverter/charger. The acceptance voltage was set at 14.4 which was too high for the BMS so it started beeping then shut the batteries down to protect them. At least I know the BMS works. So I ended up having to set the ambient temp at 90 to reduce the voltage. Now it goes up to 14.0 volts and the BMS is happy. So I should be able to keep this inverter.
Next step is to let the batteries run down to 20% state of charge then charge to see how long that takes. My inverter puts out 100 amps charge. Then I want to shut off shore power and see how long I can go on just batteries. That'll be next week.
