RE: Border closure extended

I did hear the same report as Gary about November 21st. https://www.ctvnews.ca/politics/canada-u-s-border-closure-will-likely-be-extended-until-november-sources-1.5106408

RE: Lithium Batteries

She wants to keep the charging to 50 amps each so 100a for the two. Meanwhile there have been posts that the alternator will fry from trying to charge the thirsty Li house batts. Sounds like the way to go is disconnect/disable alternator charging and just leave in the Aux start from the house feature if ever needed. So is it likely that in most motorhomes there is no DC to DC charger and the alternator is just wired directly to the house batteries and charges them with whatever output it has? Hi msith1199, The alternator is controlled by the ECM of the chassis. Most alternators have a duty cycle rating. In my case, that is 120 amps. But continuous duty is 1/3 of that, or about 40 amps. The only time one is likely to see greater amperage is if both the starter battery and the house batteries are "hungry" or if a large load is present in the house. For example the water heater on the electric setting. I deliberately added a 2nd charging path from the Chassis battery to the house bank. I do have manual control of the connection. I have seen 70 amps for brief periods of time. I monitor the voltage on the chassis battery. If it gets to 12.3, I turn off the connection. I've seen no complaints of burned out alternators. Maybe BFL13 could give us a link?

RE: Lithium Batteries

Anybody see any issues in going with one 200ah battery versus two 100ah batteries? It is preferable to have one 200 amp-hour vs two 100 amp-hour jars. It might cost more to do so.

Bert the Welder, Potting would not work well as the cells need to be cooled.

RE: Lithium Batteries

3 tons, Li are the future. There is one chemistry that can be used and charged at -40

RE: Lithium Batteries

I guess I don't follow, if your RV is in storage, why would you be charging your batteries? Lithium doesn't care about sitting at partial states of charge. Because: 1. I have solar 2. My brother destroyed an LI by freezing it. 3. I use my RV in the -30 to -40 range. Please try to read the whole thread before making replies.

RE: Deep cycle battery maintenance

If the plates are covered, then fully charge the batteries BEFORE adding distilled water.

RE: Lithium Batteries

Or mount them inside the trailer instead of outside, which eliminates the low temp operation issue and increases security. Or buy one of the brands that has internal heaters or use the heating pads offered if you'd prefer to keep them outside. The entire temperature argument is a non-issue in my opinion. This will do no good if the RV is in storage at -40. So extreme cold, for some of us is, a fact of life. No one in their right mind is going to pay a premium of $109 for a gain of 8 amp-hours. I based all my looking on 100 amp-hour jars, which are a much lower initial cost than Li.

RE: replacement air conditioner

Chewydog, There are 48 volt dc air conditioners. Some are mini splits.

RE: replacement air conditioner

Hi, I vote for the 240 volt inverter. Mini-Splits are the bomb! Here is a 115 volt Mini Split. https://www.homedepot.com/p/Pioneer-Low-Ambient-12-000-BTU-1-Ton-20-SEER-Ductless-Mini-Split-Wall-Mounted-Inverter-Air-Conditioner-with-Heat-Pump-110-120V-WYT012ALFI19RL/314096172

RE: 15.2 v during solar equalization charge - what do you do?

Hi BigHatnohorse, The computer boards in RV's dc systems are safe up to 15.4 volts. I have the Blue Sky 3024 di. I've never had a problem with over voltage. the unit is set to 15.2 volts for equalization. Time2roll the Blue Sky has extremely limited adjustment via dip switches. They sell a separate "calibrator" called an IPNPRO remote for fine tuning. It, unfortunately, costs nearly as much as the charge controller itself. Your Morningstar is a much better buy. There is a dip switch setting to turn equalization off.

RE: Installing an inverter in my Winndbago Journey

consider that when using the inverter you wish to save as much power as possible. Having it power a relay may use about 12 watts. If, on the other hand, you have shore power pull the relay closed, you save that 12 watts, when on the inverter. On shore power 12 watts is nothing. On battery power it is a lot.

RE: Needing help, evacuated, battery dead

For now. 1. start the engine on the class B 2. wait 1/2 hour 3. attempt to start the generator 4. if it starts, add a battery charger to recharge the house battery bank when ever running the generator. For the future make sure the converter is working correctly.

RE: ac unit

A new unit might use a little less power, but btu's are btu's. If you went to a minisplit unit more cooling may be available but it almost certainly will be expensive.
