Maybe I don't even need the heating pad after the plywood and foam insulation is added raising the batteries off the cold steel floor. Grab your 4-prong push-in wire connectors. Plug the two white (positive) wires from the temperature sensor into the first push-in wire connector. Our Battle Born Batteries ship with 18-8 stainless steel 5/16 – 18 1” and 1 ¼’ bolts, brass washers and 18-8 stainless steel nuts with nylon inserts. As a fulltimer living off lfp/ solar not being able to charge the batteries could be an issue as I recently found out. Additionally we don’t recommend these pads for use in Veterinary centres. For this our recommendation is either the Flexiguard 44 or the Flexiguard 55.

The heat pad carries about 15W per side, so 14- or 16-gauge wire is typically recommended for extra wire length. Take the length of wire and plug it into your positive push-in connector. This should take the fourth and final slot of the positive push-in connector. This will become the positive ring terminal. For this positive terminal, Eric used about 18 inches of wire. Heat is never an issue, in 4.5 years I've only seen a cell at 80f and that has only been twice. 45-75f is the normal cell temp range depending on season and location. I have never bough any type of heating element for a propagator. I started by deciding the approximate power rating I estimated would be required to warm the area I wanted. The voltage was decided by what transformers I has available , (Mostly 12 volts or 24 volts.) From that I worked out the resistance required. I then looked at what wire I had and measured its resistance per meter. (I would actually measure the resistance of several meters as the resistance of one meter would be quite low. ) Among the things I have use have been single conductor copper wire and plastic coated iron garden wire. The wire was then just wrapped round hooks at the end of the frame is a zigzag pattern to use up the calculated length. Sometimes I would wrap the length of wire round a sheet of plywood so it was more or less evenly spaced. I think you will find that you need a very large battery. I would estimate you would need at least 100 watts for the size you require. (And that is assuming you have some thermal insulation under the heating element and some kind of enclosure above the plants. (I also live in Lancashire and those estimates are from what I have used in the past.)If necessary, locate your extra wire. We added some length of 16-gauge wire so installation with our batteries was simplified. You want to ensure that your ring terminals (which we will hook up next) can reach towards the battery’s terminals. The heating pad can be connected to the 12v fuse panel with a switch added inline to turn it on/ off if needed. Power consumption should be roughly 6a which would be a little more than 1% an hour of my battery bank, I'm thinking it probably wouldn't need to be used more than an hour or so periodically. Note: R egarding the Standard, Large and Giant Heat Pads listed here they are not 12v they can’t be used with a car adaptor in a vehicle)

I'm not even worried about the heat generated from them other than if it will stay on for a period of an hour or so without having it turn itself off being sandwiched in the design I'm thinking about. As I said all cells can be seen/ monitored on a display panel in live time readings. Once the cells warm up it would as simple as turning the heating pad off. Today, we are proudly introducing our own branded RS PRO Adhesive Silicone Mat designed for areas where standard heating methods are challenging to apply. Our Mat is self-adhesive and has etched foil element embedded into a glass cloth supported rubber compound.After the thermal wraps are in place, wire each heating pad to the main fuse panel or directly to the lithium battery using the included 10 amp fuse (we installed ours directly to the batteries using positive and negative bus bars). Lastly, install the master control switch to allow on-off operation of the heating pads. Operation Even charging is a low C rate, .12c is max with solar, .16c is max the panels can produce but there are always loads. If the generator is needed for a boost charge then .2c (100a) is what I'll set the charger to. Picasso, I've never seen one of these heating pads in person that's I'm wondering about the placement of it.
