Thank you so much for choosing SOK Battery.
On this page, we would provide you the guide how to do troubleshooting for your batteries.
FAQ:
1.when i received the battery, why the battery voltage so low?
The SOK battery, 12V 100Ah, 12V206Ah, 12V 280Ah, 24V 100Ah, these batteries BMS has a storage mode function, when you received it, it's in storage mode, the voltage should be between 0~13V, this is normal, it doesn't mean the battery cells got over discharged. You could give it a charge, the BMS would be reactive immediately, make sure your charger has DC 14.4V~15V output to reactive it. If the charger is designed for acid lead batteries, and output voltage should be around 13.2V, it maybe NOT reactive this battery,LiFePO4 battery need charge voltage at around 14.6V
The SOK Battery, 12V 314Ah,24V 150Ah, these batteries shipped in off condition, press the button on the top lid cover, it would be on immediately.
2.why i cannot search the bluetooth for my battery?
SOK now released 2 different BMS app.12V 100Ah, 12V 206Ah, 12V 280Ah, 24V 100Ah, these model battery using the app ABC-BMSThese models battery Bluetooth, we designed a sleep mode function, when you NOT using the battery in 6 hours, the bluetooth would go to sleep mode, your phone can not search it, you could turn on the charger or turn on your loads, as long as there is current go through the battery, the Bluetooth would be on immediately.
12V 314Ah, 24V 150Ah, these 2 model using the app:SOK Battery , these 2 model batteries, if not using in 15 days, the bluetooth would shut off in sleep mode, you could give it a charge or discharge, the bluetooth would be on immediately.
3.What kind battery charger should i choose for SOK battery?
a: using solar charger controller, we would strongly suggest you choose the MPPT solar charger controller, NOT using PWM solar charger controller, The PWM solar charger controller almost non protection circuit, easily got the battery damaged.
b. using AC charger, we recommend you could choose the SOK battery charger, or you could choose the Victron smart bluetooth charger.
c. using shore power charger converter, most brands shore power charger converter support charge the lithium batteries, as long as it provide the DC 14.4V~14.6V output, it would be fine.
d: using alternator to charge lithium batteries, when you using your alternator to charge batteries,we would suggest you add a DC to DC charger, it would protect your alternator and batteries. You could check this video for explaining:https://www.youtube.com
4.Could be batteries connect in parallel and in series ?
Certain batteries have limitations as to whether they can be connected in parallel or series.
a. SK12V100,SK12V100H,SK12V100P,SK12V100PC,SK12V206,SK12V206H,SK12V206PH,SK12V280H
These models battery support connect in parallel & in series.
For example, if you need 12v 1000Ah battery bank, you could connect 10 pcs 12V 100Ah in parallel or 5 pcs 12V 206Ah in parallel.
If you need 48V 1000Ah, you could connect 5pcs 12V 206Ah in parallel as one unit, and then connect 4 units in series, it would be 48V 1000Ah system.
Please note, NOT connect over 48V system,NOT connect over 4 pcs batteries in series. For connect in parallel, no limitation.
b.SK12V314PH,SK24V150PH, these 2 models support connect in series, but if you connect in series, the commucation function maybe has issue, so, if you don't need the commucation function, it's ok for you connect in series, if you need commucation functiom, make sure NOT connect them in series. Also,NOT connect over 4 pcs batteries in series,connect in parallel, no limitation.
c.The BMS within the battery only is intended to monitor and balance the cells within the battery enclosure it is mounted in, thus, when batteries are in series one battery has no idea what is going on with the rest of the chain. This also means that it cannot match itself to the other batteries in the chain because it is unable to monitor the charge levels of the other batteries.
For batteries to work in series, all batteries in the chain must be at the same charge level. In order to run without an external balancer, then you must fully charge the batteries to 100% with a 12 volt charger BEFORE connecting them in series. Systems without balancers should be checked manually monthly for drift in charge level. This is accomplished by fully charging the system and comparing the voltage of the two packs. If they are more then .3v different, then it would be required to top off each battery individually. If however, you do add the external balancer, then the balancer is able to monitor and correct for differences in terms of SOC% across the battery string.
We would strong suggest you add the balancer if you connect batteries in series.
d.What Battery Balancers are recommended?
Multiple options are available, listed from highest recommendation to lowest:
Victron Battery Balancer (24/36/48v systems)- available here: https://www.currentconnected.com/product/ve-batbal/
ISunEnergy Battery Balancer – (24/36/48v systems) available here: https://www.amazon.com/iSunergy-Equalizer-Balan…
5. Recommended Settings for Victron SmartShunt, BMV 712 & Lynx Shunt

6. Do i need to add the fuse to protect the batteries ?
Yes, we would suggest you add the fuse on each batteries positive terminal. 150amps fuse would be good enough for SOK 12V, 24V batteries.
