Wow, great information. is there a battery charger that is reliable, has the features, and is too expensive tat you would recommend?Good choice. I've been happy with my SOK batteries.
A few things to keep in mind with the batteries. They have a rated max continuous discharge of 100A. If you put the two batteries in series you have 24V with 100A max discharge (2400W). If you put them in parallel you have 12V with 200A max discharge (2400W). Either way you want to keep your inverter below 2400W to avoid asking the batteries for more amps than the rated max continuous.
If you put the batteries in series for 24V you will want to first wire them together in parallel. Then connect a 12V LiFePO4 friendly battery charger. Put the positive lead on one battery and the negative lead on the other. Charge the batteries to 100% SOC. Once charged you can disconnect the charger but keep the batteries connected in parallel overnight so they stay at the same SOC. After that you can set them up in series as needed. At first I simply fully charged each of my two batteries one at a time and then put them in series. I then had some issues when they were being charged in my system. The two batteries got way out of balance when very close to 100%. Once I performed the steps I just outlined they have been working together very well. I doubt this is specific to SOK batteries. Those steps should be done with any batteries that will be put in series.
BTW, how’s the off grid living treating you?
