Review: Keeping my RV Batteries Alive through Winter - I ordered these (2) heating pads after watching a Youtube video regarding keeping LiFePo batteries above freezing, as this is required of these batteries. I bought 2 of these heading pads, and have installed 1 of them directly to the side of my 4x100Ah battery bank (using the adhesive backing to attach them directly to the sides of the battery. Even though the pads come with a thermostat that turns them on when temps dip below 40F, I installed the pads through a temperature controlled relay (https://www.desertcart.com/dp/B09531FDPN?psc=1&ref=ppx_yo2ov_dt_b_product_details). So far, the temperature within my RV has dipped below 20 degrees, and the batteries have remained at about 38 degrees. The heating pad is drawing about 70 watts when it is activated. If the 1 heating pad is not enough to keep the bank above freezing, I will connect the 2nd pad to the opposite side of the battery bank (then will draw 140 watts). Trying to avoid running down my battery bank, in the process of keeping it alive. So far, the heating pads have worked well. I hope to give another followup in the Spring. ## Features - [✅ Trusted Facon Brand]: As a leading name in RV accessories, Facon is dedicated to providing high-quality, innovative solutions designed to enhance your outdoor adventures.

Otherwise it turns off way before a comfortable temperature. **Q: Picture shows two, will there be one or two in this order.** A: Hello, this link are 2 packs package. You will receive 2 pads if you order 1 with $73.99. Thank you for your attention. **Q: Could this be used to warm batteries?** A: I imagine it could but I do not know what the max output power is. I wouldn't until you are sure of the pads max operating temp and check the battery specs to see it's heat tolerance. Essentially these are just heating pads with a built in on/off sensor. It would warm whatever it is stuck on. **Q: Can you connect this directly to pos/neg battery terminals on a 200Ah 12v auxiliary battery?** A: That is the intention. However, highly recommended to add the switch pack. At least in an Airstream - which ducts heat to the tanks - you have the option of turning power to them completely off. Also, while your RV is idle with batteries still in place and nothing in your tanks, you can insure they're off and not draining the battery when outside temps go below 42 (when they automatically turn on). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Battery warmers *by T***R on February 2, 2026* Perfect, just what I needed. ### ⭐⭐⭐⭐⭐ Keeping my RV Batteries Alive through Winter *by M***. on December 1, 2022* I ordered these (2) heating pads after watching a Youtube video regarding keeping LiFePo batteries above freezing, as this is required of these batteries.

Before installing I checked that the thermistors turned on and off. However, after installing, one pad didn’t heat at all, verified by zero current draw, and the other pad’s wattage fluctuated wildly between zero and c. 65 watts, and did not provide any appreciable heat. I’m swapping both pads out for another set to see if my luck improves, but am not looking forward to scraping the old ones off, and finding a baggie to put the bits and pieces in so that they can be returned as per Amazon’s request. Update: before returning the heater pads, I heard that it’s possible to remove the embedded thermostats, and connect the wires, so that the thermostat is totally bypassed. This I did, and now, with an external controller, the pads work perfectly, drawing 65 W each. ## Frequently Bought Together - Facon 7-1/4" x 25" 12V RV Tank Heater Pad with Automatic Thermostat, 2Packs, QAI Certified, Prevents Freezing for Fresh, Grey, Black Water Tanks, Up to 50 Gallons - Facon 12Volts Switch Box Panel, 30Amps Rocket On&Off Switch with Red Indicator Light for RV Tank System, IP66 Waterproof Control Gang Kit System for RV Tank Heating Pad - Facon 3" x 13" RV Elbow Pipe Heater Pad, Work for 3" Elbow Pipe, 12V Tank Heater Pad, for RV, Camper, Travel Trailer and Motorhome, DC 12Volts-13.5Volts, 3Packs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/101980261-facon-7-1-4-x-25-rv-tank-heater-pad](https://www.desertcart.hr/products/101980261-facon-7-1-4-x-25-rv-tank-heater-pad) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-25*
