how to do troubleshooting for SOK battery? replace BMS for SK12V100H and SK12V206H • how to replace the BMS... replace BMS for SK12V280H • How to change the BMS ...
Hi, I am looking at using the Marine 100ah version for a 12v sump pump backup system that is a safety measure for when utility power goes out. Upgrading from an old deep cycle AGM battery that decided to go bad. The Lifepo4 battery will only be used with the backup sump pump during periods that the power goes out to protect the basement from high ground water if not at home or until we hook up the portable generator and then have long waits before being needed again. So a longer charging time is not an issue. My question is what is the minimum recommended charging amps that can be used without adversely affecting the battery cells? Looking at various quality smart chargers but don't wait to go bigger with higher cost then actually needed. Top runner is the victron smart chargers which are available at 7, 13, 17 and 25 amps. I was going to submit this via the Marine Battery vid, but that one doesn't allow comments. Thank You
Not sure how you want to protect this battery. If the load over rated power, it would shut off . Just make sure charger voltage at 14.4v-14.6v, charger current NOT over 120amps , this is enough protection.
Hello Kim! I have a single Sok206 which was purchased May 21 2021. My battery is connected to 460watts solar panel with vitronMPPT 100/30 charge controller. 3 weeks ago my battery stopped holding the charge and I ordered victron IP22 30amp charger. I downloaded ABC-BMS Sok Battery apps but apps can’t find the Bluetooth in my Sok206 battery. Please advise 🙏
This old version bms no Bluetooth function. Check the battery cells voltage , if battery cells voltage in normal, charger output voltage ok, should be bms issue . Contact sales@sokbattery.com
I received my new SOK battery today and its dead, the voltage at the terminals is 0.6v. When i connect it to my charger the terminals show 14.5v but even after leaving it for a few hours no charge is achieved so when i disconnect the charger the voltage drops to 0.6v again.
@@sokbattery On my SOK 100Ah | 24V - LiFePO4 Lithium Battery when I compare the reading between its BMS and my 6 /12 digit Keithley DMM6500 there can be a +/- 25mV difference per cell voltage and meter..
Can you tell me the most current version of the Android app? I installed Version 2.0.30 Release 2021 - 10 - 10 on my phone last week. It looks a little different than your copy, although it may be functionally the same.

charge current NOT over 70amps would be good enough.
Do you have any idea how to set a maximum load limit? For example 90% or 95%, to protect the battery?

you could send an email to sales@sokbattery.com
@@sokbattery you don't reply to emails I've sent you a few already
@@paultaylor8739 we relied email every day. did you check spam folder ? or what's your email address?
@@sokbattery thank you, sorry your reply went straight to my spam folder, I've replied back to you now with screen shots of the faulty battery
Is there a way to check the battery cell voltage calibration? If its off, is there a ways to recalibrate each cell BMS voltage indication
No need the battery cell voltage calibration... it's changing when you charge or discharging it. the APP show the battery cells at the bottom...

Update on Google Store, it has new version.
