This should be a small black panel with two wires (one red and one white) exuding from one end, and one black wire from the other end. First, in Step 2 it now says “Plug the two white (positive) wires from the temperature sensor into the first push-in wire connector.

Heat Pad with Battle Born Batteries How to Use a Heat Pad with Battle Born Batteries

Miller Tech lithium batteries are lightweight, non-toxic, and long lasting compared to traditional lead acid batteries. Please keep in mind what temperatures the battery will be exposed to, because regular exposure to high temperatures (>100 degrees Fahrenheit) will accelerate battery aging. Plug the two white (positive) wires from the temperature sensor into the first push-in wire connector. When the nighttime ambient drops to 25f and gets up to 45f +/- the cells will hold at a low 38f +/- and then warm up some during the day with use and charging which is good for my use pattern.

This morning at 5am compartment was holding at 47f but the cells were 34-35f and was thinking great but at 9am they dropped another couple degrees and one went to 31f. Bottom layer is Reflectix, middle layer is 1" R-Matte plus-3 (insulation board composed of a closed-cell polyiso foam core bonded to reinforced aluminum facers) R6 rating. The only thing that I'm thinking about is with the built in temp on the heating pad will it be turning itself off because it will be within the sandwich under the batteries and not in an open air space of holding tanks? I would personally put the batteries in a insulated container, then add a thin sheet of conductive material like sheet aluminum over the pad so that the heat it produces can warm up your entire battery bank.

Well I have yet to make the Lily of the Valley Lithium move just yet and this has been one of the issues Its challenges at low temps.The wires attached to the sensor are routed out and connected to the In-sure connectors and/or battery terminals. I would actually measure the resistance of several meters as the resistance of one meter would be quite low. Once everything is aligned, tape up the push-in connectors and ensure that all wires are organized and tucked away properly. We have a solution to this problem as our dedicated, carefully selected heaters offer high-quality while keeping your budget under control.

It is very important to ensure your expensive investment in LifePO4 batteries do not freeze while they are being charged.

Besides the heat pad, which is set to come on about 38°F I also have a total disconnect of the batteries from everything set at about 35°F. Plan "b" of the small heater is working as a bandaid for now but rather have something running in the backyard that will work if I'm not around. I, being the ever bright engineer, took four eight foot lengths of 3" ABS pipes and laid them on the nearly flat roof of the patio. Eric, one our expert sales technicians, walked us through the process of setting up a heat pad with our batteries.

I've had some cold temps for a couple of mornings to test my heat pad with external digital thermostat.I don't know how effective this would be but I thought it could a handy way of making use of energy that would otherwise be wasted. The warming elements usually found on a spool by specific ohms per foot or you might find what you need in an old fridgerator.
