Notice: NOT MIX USING DIFFERENT CAPACITY OR MODEL BATTERIES. Connect Batteries in Parallel When you connect SOK Batteries in parallel, it will increase the amp-hour capacity, the charge/discharge voltage will remain the same, but charge/discharge current will change. For example, if you connect 2 pcs SK12V100 in parallel, the charge voltage still 14.6V discharge cutoff voltage still 10.4v, but it could accept high charge/discharge current, double than one single battery, charge/discharge current would be 100Amps/200amps. It would be a 12V 200Ah battery bank. if you connect 4 SK12V100 in parallel, charge/discharge current would be 200Amps/400amps. It would be a 12V 400Ah battery bank. SOK Battery Support connect in parallel up to 10 batteries. Connect Batteries in Series Notice: 1.Please note for connecting in series: If you are going to connect the batteries in series they need to be at the same State Of Charge (SOC) before they are connected. 2.SOK Battery support NOT over 4 pcs in series.(SK24V100 Support 2 pcs in series) Connect Batteries in Series will increase the battery bank voltage, the capacity will remain the same. For example, if you connect 2 SK12V100 in series, it would be 24V 100Ah battery bank, 24V 100Ah. If you connect 4 SK12V100 in series, it would be 48V 100Ah battery bank, 48V 100Ah. Connect batteries in Series and Parallel. Notice: 1.Please note for connecting in series: If you are going to connect the batteries in series they need to be at the same State Of Charge (SOC) before they are connected. 2.SOK Battery support NOT over 4 pcs in series.(SK24V100 Support 2 pcs in series) If you need big battery bank, you could connect batteries in series and parallel. For example, if you need 48V 400Ah battery bank, you could connect 4pcs SK12V206 in series as one unit, and then connect 2 units in parallel, totally 8pcs SK12V206. The new battery bank will support:48V*200amp=9600W inverter. The last, attach one photo for reference, customer connect 16 pcs SK12V206 in series and parallel. 4pcs SK12V206 in series as one unit, and then connect 4 units in parallel. 48V 824Ah New battery bank.

SOK Release our new BMS at the end of 2021, with bluetooth function. few steps to DIY a 12V LiFePO4 Battery Bank with SOK BMS P means positive, N means negative Connect the Bus bar and balance wires. connect the N1 with BMS B-, connect the P4 to your inverter/charger directly. connect the BMS P- with your inverter /charger Last, get a location for the low temperature sensor.

Will set up Victron BMV-712 Battery Monitor and SK12V100 1)Open Victron Connect, connect to the BMV battery monitor. Click on the settings wheel 2) Battery Capacity: Total Ah of your bank of batteries Charged voltage: 14.4V but note that this number should be about .1 or .2 volts below the charging voltage set in your charging device Discharge Floor: 0% Tail Current: 2-4% is good Charged Detection Time: 3m Peukert Exponent: 1.05 Charge Efficiency Factor: 99% Current threshold: 0.10A Time to go averaging period 3m Battery Starts Synchronized: blue button should be to the right State of Charge: leave alone Synchronize SOC to 100%: Leave alone, this device will sync itself at the top of the charge Zero Current Calibration: Leave alone

Will set up base on Victron 100/50 model and SOK12V100 model 1) open to VictronConnect App and choose the MTTP Model. 2) inside click on the settings wheel in the upper right hand corner 3) select the top line that says “Battery” and your settings are right there. Change “Battery Preset from “Rotary Switch” to “User Defined“. Now set it up like this: Absorption Voltage = 14.6v Float Voltage = 13.8v Equalization Voltage = 14.4v (We actually want Equalization Time to be set to zero. That is done under “Expert Mode“). Automatic Equalization should be set to “Disabled” as should Temperature Compensation and Low Temperature Cut Off. 4)Slide the “Expert Mode” slider over and set it up like this: Now set the Maximum absorption time to 30 minutes per battery that you have. Make sure automatic equalization is disabled. Make sure Equalization duration is set to 0 minutes.
