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).

    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.
