Battery warming for remote cold-weather cart use
Hi everyone, I live in Wisconsin and have built a 48v Club Car DS using CartsUnlimited c54 kit.
I would like to use it for hunting, but WI deer season being late Nov brings a lot of cold weather questions into play for an electric cart. Temps can be sub zero in the worst years. I am toying with the idea of running and additional voltage converter to an auxiliary switch, and using the cart’s battery pack to power 6 motorcycle hand grip heating pads mounted to the bottoms of the batteries to keep the batteries warm while the cart is sitting idle out in the woods. Wondering if anyone has thoughts on this or have tried anything similar? Batts are water/acid, and there are 6, 8 volt batteries. Link to what I am thinking of using as the heating element: https://www.denniskirk.com/kimpex/ha...SABEgJOBfD_BwE Last edited by lwildbeard; 10-12-2020 at 11:53 AM.. Reason: Would like this added to the custom carts section instead of the troubleshooting section. |

Re: Battery warming for remote cold-weather cart use
Being in Southwestern Pennsylvania we can have some cold hunting weather.....not like you get....but anything below freezing has a negative effect on batteries.
At one point in time I was toying with the idea of hooking up a small 12V blower type heater for my cart. I didn't do that as I was somewhat concerned about a "glow" heater with the gas that is emitted from flooded lead acid batteries. With my current Lithium batteries that would not pose a problem....but I've not really reconsidered the heating option. Likely my only concern about the type of heating your looking at is...will these "stick" to the batteries? It may be that if they don't stick...or even have a small gap between the batteries and that heating unit, actual battery keeping warm may not occur. |

Re: Battery warming for remote cold-weather cart use
My plan was to create some 2 layer drop-in floors for the battery trays out of thin sheet metal and have the heating pads placed in between the 2 layers so the batteries would be sitting directly on a radiant heat source. I figured I could throw a blanket under my seat to help preserve the heat while the cart is sitting in the woods as well. Not sure if it’s plausible or what kind of battery drain 6 of these pads would impose either. Just brainstorming and trying to come up with a solution for cold weather electric cart use.

Re: Battery warming for remote cold-weather cart use
You may wish to consider installing a separate 12V Marine battery for your heat power source. I have one that connects my Winch's & Lights so I don't put additional power pull from the pack.
Also, do those heating pads have the amps that they pull listed? I looked at the PDF file instructions and it didn't list how many amps those pull. I realize they are "just" grip warmers......but it's hard to say how much of a drain they will put unless you know the amps. |

Re: Battery warming for remote cold-weather cart use
Well....I'm no engineer but if the heaters are rated for a total of 7.5amps, that (I think) would mean the heaters would draw 7.5amps per hour.
So, if your battery pack is rated at 125amps, after 4 hours of running your heaters the battery pack would drop from 125amps, to (4x7.5=30) to 95amps. I think that's how it would effect your battery pack. |

Re: Battery warming for remote cold-weather cart use
You might want to think about lining your battery compartment with insulation. They make different engine insulation that you can use to line your battery compartment. Using one or two heating pads would be more than enough to keep it warm and not be a great battery drain.

Re: Battery warming for remote cold-weather cart use
However you do this I would do as Dave suggested and use a separate battery.

Re: Battery warming for remote cold-weather cart use
Man, even down here in Louisiana, cold weather slows the cart significantly, and drains the batts. Good luck with your project, let us know how it works out.
