## Questions & Answers

**Q: Can these be used to heat a water bed mattress?**
A: If you’re only looking to keep it from freezing I imagine it’d work fine. 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

### ⭐⭐⭐⭐⭐ 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. 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.amazon.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.

### ⭐⭐⭐⭐⭐ It Works
*by X***R on January 11, 2023*

A bit expensive (for me, anyway), but I don't think it's unreasonably so.Can't tell quite yet if the temp control functions as it ought to, but I'm not too concerned.I did fuse it and I did put an on/off switch in the circuit because I'm using it for an off-label use: as a battery warmer for a standalone solar project. (Right after I ordered this I saw a YT video on Will Prowse's channel where he discussed this very use.)Anyway, I already have the smaller version in another project (lithium battery-powered, remote weather station) and it works great.Bottom line, consider this item.5 stars.

### ⭐ Did not work and my tank froze and cracked. UPDATED REVIEW
*by C***T on January 23, 2022*

DO NOT BUY! This company does not stand behind their products. I bought these for my RV tanks and one did not work and my tank froze and is now cracked. The company says that they will not pay to fix it because their product failed. Poor business practices when a company wont stand behind their products Yes I installed them properly I have been doing this kind of work all my life. UPDATE! After posting this review I was contacted by the owner of the company. After a short phone conversation he said that they will compensate me for the damage is done to my tank. Frank was very nice and wanted to do the right thing. I want to be very clear I have used dozens of their tanketers and have only had 2 fail and only one caused damage. This company makes a quality product and they stand behind it when something happens and at the end of the day that's what really matters. They paid to replace my grey water tank that was damaged and apologized numerous times for the inconvenience. Thank you for doing the right thing and standing by your product. I will continue buying their products. Thanks guys!
