Safety Advantages of the SOK 12v 100Ah Marine Grade Lithium Battery: An Excellent Choice for Solar Energy Systems

When it comes to applications where safety is a top concern, manufacturers across industries are turning to Lithium Iron Phosphate (LiFePO4) batteries. LiFePO4 batteries are known for their excellent thermal and chemical stability, which makes them the ideal choice for high-risk applications.

The LiFePO4 battery remains cool in higher temperatures and is incombustible in the event of rapid charges, discharges, or short circuit issues. Unlike traditional lithium-ion batteries, LiFePO4 batteries do not experience thermal runaway, as the phosphate cathode remains cool and does not burn or explode during overcharging or overheating.

LiFePO4 batteries offer numerous safety advantages over traditional lithium-ion batteries making them the perfect choice for users seeking a safe, reliable, and long-lasting power source for their motorhomes, boats, RVs or off-grid.


How do I connect to the Bluetooth?

This battery now features an updated BMS that puts the Bluetooth function into a deep sleep mode when the battery is not in use. The Bluetooth will be activated once the battery is charging or discharging.

To connect to the SOK Bluetooth battery, search for ABC-BMS on google or apple store and install on your phone.  When you open the app, it will automatically connect to whichever battery it finds first.  If you have multiple batteries, you can choose which one to connect to by clicking on the top menu and then selecting the battery that has a serial number correlating to the sticker on the top of the battery.

You will notice the SOC and capacity reading, but they are initially incorrect.  In order to make them correct, you have to do 2 discharge/charge cycles.

Does this battery have Low-Temperature protection?

Yes!  The battery will prevent charging below 0°C in order to protect the cells while continuing to allow discharging.

Can I use my old Lead-Acid Charger?

This is not a simple “yes” or “no” question.  If your charger has an equalize feature that exceeds 14.6v, then it absolutely cannot be used.  The maximum charge current of a SOK Battery is 50 amps, so your total combined charge current may not exceed 50a * [number of parallel batteries].  You must also check the output voltages of the charger throughout a full charge cycle; if they exceed 14.6v they cannot be used.  It is optimal to have an absorption voltage of 14.6v and a float voltage of 13.8.  The battery isn’t totally picky regarding the float voltage, but we recommend 13.8 for optimal lifespan.  If you are limited on parameters, it is best to be on the lower-voltage side – you may sacrifice a bit of capacity, but longevity will increase significantly.  Additionally, if your batteries get to a very low SOC, then they can draw more power from your charger than it is designed for leading to nuisance blown fuses & circuit breakers.

Can the battery be installed on its side?

Absolutely!  With no acid or venting, this battery can be installed in any configuration except for upside-down (terminals facing down).

Who makes the SOK BMS?

The BMS is custom made by SOK battery, designed by SOK’s in-house engineers and manufactured to their strict quality control standards.

What is the warranty policy, and how do I get any problems with the product fixed?

These batteries have a 7 year manufacturer warranty.  If you ever have any issues with the product, please email us us.  Our team is on standby ready to help you.  Our business relies on happy customers with working solutions, so if the battery is not working for you it is our job to provide the necessary after-sales support to turn a product into a solution.  We have the faith and have done the testing to know these batteries will last a long time, and we are here for you through the entire duration of ownership.

    Delivered in 4 days, well done. I love the fact that the battery is so much lighter than the AGM battery it replaced.
