Can you ship to Hawaii & Alaska?
We have currently suspended complete shipping to Hawaii & Alaska. You may arrange your own HAZMAT shipping from our warehouse, FOB Origin. Contact us if you would like to do this.
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. If you need to charge the battery in sub-zero temperatures, we recommend adding a heating pad that can be turned on to warm up the battery prior to charging.
What temperatures do the batteries need to be brought out of the cold?
The lowest safe storage temperature is -22°F, so any temperatures below this, you should bring them inside or add a heating pad of some sort, but keep in mind if a heating pad runs out of power and the battery falls below -22°F, damage may occur.
Does this fit into a standard “group size” battery box?
No, these batteries are just a bit too big to fit into your standard battery boxes. Many of our customers have had great luck installing into tool boxes or similar enclosures that provide protection from the elements. The metal-cased batteries are not waterproof. The Plastic 206ah battery can be installed in wet environments such as the tongue of trailers, in which case they fit great with the factory battery boxes removed.
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 lifepsan. 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.
Do you offer free shipping?
We are a small mom & pop business, there are 3 of us here running this operation.

4 reviews for SOK 12V 100Ah LiFePO4 Solar Battery
Rated 5 out of 5
I purchased two SOK 100ah for my Sprinter Van as a drop-in replacement to the existing lead-acid batteries. We wanted a power setup that would take less space and be able to discharge down below 50%. So far these batteries have been great. Dexter and the team at Current Connected have been amazing to work with. Being a new van owner I’ve had lots of questions come up, and they have ben super helpful walking me through setup and configuration. Definitely would purchase again from these guys for the customer service alone.(Video) SOK Battery: Best budget 12V LiFePO4 is back in stock

Susie –(Video) New Battery! Marine Grade SOK 12V 206Ah LiFePO4 for $.39 per Wh
Great battery. So very pleased even for use in a chicken coop and also to run a fan in a small greenhouse. I also purchased the Victron controller and shunt from them. They have been so helpful in answering all my questions that I have had. I will be shopping at with them again as needed. They have great videos that Dexter also explains very well. They are very conscious about getting the products you order shipped out to you as fast as possible.
This company has the best customer service that I have received from purchases in a long time. Thank you, Jarrett and Dexter for your excellent customer service and quality products that you sell. You have both been a blessing to do business with. God bless you both, keep it up.
Thank you so much.

Peter Roy (verified owner) –
I inadvertently purchased a 206 ah SOK battery from them thinking it had a 200 amp BMS. When I discovered my mistake I called them and they quickly helped me place the order for 2 100 ah SOK’s. When they arrived one of them had 2 red caps instead of a red and a black. Again they quickly sent out replacement cap. They have been top notch every step of the way, A+ customer service. I will be ordering more parts to upgrade my RV Off grid capabilities.
