RE: Edison Batteries

Hi Phil, Yup I got it wrong (again). Mind you 1000 cells would be pretty amazing to have LOL-but then weight WOULD be an issue.

RE: Surge Protector?

Why? Because the cheapo doesn't protect you from much. Because the cheapo doesn't look for reversed polarity, or open ground, or bad neutral. Because the cheapo doesn't disconnect on low voltage (imo 104 is too low, but that's another story). Three strikes and the cheapo is *out*. As I said earlier, I prefer an autoformer, since the "silent" damage is more often from low voltage. you want a multi-function surge protector. $250 and up. not the $90 special. bumpy Why?

RE: LIthium battery upgrade - Complete!

Hi Eric, Please keep us updated on how they behave.

RE: ARP Refrigerator Protection

Hi, I have it installed in my Fridge. It has been great for my peace of mind. It has gone into protection mode 3 times since installation. All the times were in cold weather.

RE: Edison Batteries

Hi Phil, Their other advantage is zero plate deterioration, so after 30 years, change out the electrolyte and start over! The 112.5 amp-hour is 3.2 inches x 5.6 inches x 14.5 inches, weight 14 lbs. (times ten cells). So for 112.5 amp hours @ 12 volts. 32 inches x 56 inches x 145 inches. A huge space issue. When I first read it--I thought each cell was 140 lbs.

RE: Surge Protector?

Hi HarmsWay, I use a Sola Basic which offers three levels of boost (at 110, 100, and 90 volts) and one level of buck (135 volts). I use an add on surge device which offers much more protection than the PD, SG, or Hughes. I do manually check voltage under load, and polarity before I plug in the RV. If that shows lots of voltage drop I add the Sola to the power path. I do lock it down enough to prevent casual theft, but in these days of battery powered cut off wheels it would not stop a determined thief. The Sola units are sold in Mexico, so to get one you need to have a friend who will purchase and transport it for you (or make a Mexico trip). http://www.isbmex.com/productos/corrector-de-voltaje-8-y-4-kva The Hughes offers the same level of surge protect as the PD. I don't know if the SG unit is more capable, but I doubt it. Do you use one of those units? They seem quite large so I assume you keep it outside. Any issues wrt theft or weather?

RE: Surge Protector?

Low voltage causes more damage that surges. I prefer to fix that by using an autoformer. BTW anyone who wants to prevent brown outs should consider the new Hughes autoformer which does test polarity, bad neutral, bad ground, has limited surge capability, and of course corrects low voltage. https://hughesautoformers.com/wp-content/uploads/2015/06/led-display-home-trans1.png width=400 http://hughesautoformers.com/

RE: House batteries off gassing with Tripp Lite

Hi, Sounds like a shorted cell. Do disconnect the batteries asap.

RE: House batteries off gassing with Tripp Lite

Have you measured the charging voltage?

RE: AT&T Unlimited Price Increase

Hi, My t-mobile is 3G and I find it works well. It throttles at 28 gigs of hot spot now and is unlimited 2G after that. On the device itself the connection is LTE which I understand is 4G?

RE: Using NOCO G7200 to desulfate a pair of T-105's

Fully charge the batteries first. Pulse mode--no one really knows if this works. It may not hurt to pulse charge.

RE: Using NOCO G7200 to desulfate a pair of T-105's

Do one pair at a time. Read the manual for charge times. Four hours may not be enough.

RE: My Cheap Heat install

That is why I have 3 shore power cords. The OEM 30, a 20 and a 15 amp. The additional ones power outlets intended for heaters in the winter. My peak load is 7000 watts (measured). I have a break out box intended for use with a 50 pedestal which includes breakers for 30 amp (one leg) and dual 20 amp lines (the other leg). Cheap heat is now fairly priced but still lacks (for me) one essential item. I prefer to use various stand alone heaters where I limit power to no more than 600 watts. I've replaced all but 2 outlets on my RV to allow me to draw full power from them safely. I use an autoformer which allows me to have little or no voltage drop to the RV, no matter the power source. That means my heaters do run at their rated wattage. Running 1,500'watts on a 15 amp circuit will be running just over 12.5 amp slightly greater than 80%, and with the voltage drop over an extension cord is not a great plan.

RE: RV tech. help on what sealant to use?

Don't use silicone. The makers use something called "monkey tape". There are better products such as Pro Flex.

RE: How will this affect RVing. Very interesting video.

Hi Phil, No need to heat the entire space. Use a seat heater. They consume about 7 amps per hour (84 watts) and will keep you comfy. Let's see--17kwh / 84 watts = 202 hours of staying warm.

RE: Edison Batteries

Thanks Phil for having a look to find more info. It is too bad they are so low on capacity vs weight. Looks to me as if a stationary battery bank would be great given their ability to be flattened. That makes them better than LI--plus I doing thing there is an issue with cold.

Edison Batteries

Hi Folks, Has anyone considered using Edison Batteries? (Nickle Iron). http://ironedison.com/ and http://www.zappworks.com/index.htm A FAC page here: http://ironedison.com/technical-info

RE: My Cheap Heat install

Hi, Because you can't run 1800 watts on a 15 amp household circuit, without exceeding the 80% maximum for continuous draws. So visiting friends and using electric heat becomes problematic. Hi, The 1800 watts is one of my objections to the system. 1500 would be so much more useful. :h Not sure why, at 1,800 watts it is drawing 15 amps, you still have 9 amps available when the furnace is running. If you need more just turn the furnace off for the time needed.

RE: T-Mobile changes to one plan

Hi ramgunner, I do not have the add on. 3g is fast enough for me. It is throttled after 28 gigs.
