Yes we do Glenn, I'll explain how to choose the best option for your setup.

The main things to consider when choosing a battery heater for a lithium phosphate (LiFePO4) setup is matching the heater to your battery size, where the battery is mounted and how cold it gets where you camp.

Feel free to reply back with that information if you'd like assistance choosing a battery heater.

What winter items or essentials are you powering during cold seasons?

I have this battery in a hoof trimming chute. It is used in all weather in upstate New york. So it can get down to 10 to 15°. Sometimes colder. The battery size is a 36 volt at 20.5 by 10.6 by 8.66 inches. It is a battery with a plastic case. I hear it as best to heat a lithium battery from the sides so I would be looking for a heater that would wrap around the battery. It could either be powered by a 110 v outlet for by the battery itself. Hopefully it would be thermostatically controlled to control the heat output. Let me know if you have anything available or if you need more info. Thanks

@GlennG thanks for getting back to me. I’d go with Kat’s Heaters Thermal Battery Wrap # KH22300. This heater wraps around the battery and heats from the sides, opposed to underneath. It’s also a larger 160 watt, so it’s a much better fit for the colder temps you see in upstate New York. Adding a little insulation around the battery compartment would help even more in extreme cold, but I think this would be your best option from what we currently carry.
