RE: Inverter and battery sizing to power my camper microwave

LaneW, Consider using a dedicated female plug--one for the generator, one for the inverter. OR Use an inverter/charger that allows for load support.

RE: Inverter and battery sizing to power my camper microwave

Hi, Inverter loses are about 12% 1350 x 1.12 = 1512 watts / 12v = 126 amps = no problem running microwave Just choose a battery monitoring system that allows 100 amps to be drawn from the battery bank. Do wire the batteries in a balanced manner.

RE: Tax refund scam Canada

Thanks for the heads up free radical

RE: yet another door look bites the dust

Hi, As we get to -40 I do not want an electric lock of any kind.

RE: Verizon Grandfathered Unlimited Plan

I do have an unlimited plan from Bell Canada that covers me in North America for data. It isn't cheap.

RE: yet another door look bites the dust

Since you are in a class C, it doesn't matter but you should be able to unscrew and remove the lock from inside the RV. When mine broke, I had no problem finding a replacement at an RV parts store. I never saw an all steel model. Mine has plastic parts on the inside. Thanks for the reply. Except that the screen door covers one of the screws. What a 'smart' design.

yet another door look bites the dust

Hi, Does anyone have a source for a trimark all steel lock? It's a good thing I'm in a class C. Being locked in is not much fun.

RE: Toad Battery Charger

Geobiker, Look into dc to DC chargers. Mine is from Renogy https://www.renogy.com/12v-20a-dc-to-dc-on-board-battery-charger/?gclid=Cj0KCQiAw8OeBhCeARIsAGxWtUzaPZqVInymb-g7Moqo_LmTN-8OouwaIYnCfvpbD1hVVJPXIhFVIwgaAitWEALw_wcB

RE: Fuel tank leaks when we fill it

If it is diesel there is little chance of ignition. You could fill the tank until the first click off happens.

RE: Effect of no absorption on LiFePo4?

Time2roll, I have seen articles that suggest every 30 cycles or days that the bank be balanced. https://s2.solacity.com/wp-content/uploads/2018/08/xLiFePO4-charging.gif.pagespeed.ic.yG7HJ5J6K3.png width=395 https://www.solacity.com/how-to-keep-lifepo4-lithium-ion-batteries-happy/

RE: EV alternative for light/medium duty trucks

One problem with ice engines and H2 is nitrous oxide may be produced. It has something to do with the temperature. I don't have a good understanding of the problem--just that it requires a special design. Fuel cells don't share that problem, so far as I am aware.

RE: Effect of no absorption on LiFePo4?

Hi, My (limited) understanding is that there is a specific voltage needed to balance the cells. That is set by the battery management system. I don't know what that number is.
pianotuna 01/22/23 08:42am Tech Issues
RE: Effect of no absorption on LiFePo4?

Ralph, Quite the opposite. LiFePo4 do not want to be charged to 100%. They do want to be balanced charged once per month.

RE: EV alternative for light/medium duty trucks

map40, South Africa has been having problems for about ten years. We need to wake up and be proactive. The area of the city I live in has old tired infrastructure. There have been at least 6 outages in the last 12 months. So far they are merely annoying. But I am considering getting a battery and using my back up psw inverter.

RE: EV alternative for light/medium duty trucks

nickthehunter, Currently in South Africa there are rolling black outs. About 8 hours per day there is no power. Their power comes from...nuclear.

RE: EV alternative for light/medium duty trucks

Grover I'm all for nuclear power, if you can tell me how and where to safely store the waste. Until that happens I'm anti nuclear.

RE: Replace fridge with different model?

If you don't boondock consider a 120 volt unit.

RE: A/C problem

I am in a unit that does that. I don't think there is any power shedding--but that could be it too.

RE: EV alternative for light/medium duty trucks

Does anyone know the wattage on the battery heaters used in EV's? It depends on the car Don. But generally speaking EV’s do it different than ICE cars. Unlike an Ice car that uses an electric element to heat metal, most EV’s use the power from the battery to heat itself, or in many cases the coolant which is circulated. But that only happens down till about 20 percent battery and then that gets turned off so the battery isn’t depleted. It also doesn’t heat it unless the owner decides to either pre-condition the battery in preparation for charging or if the owner wants to warn the interiour and defrost the windows. Even if the car is plugged in the power will still come from the battery, but the battery will be charging because it’s plugged in. The power for everything always comes from the battery. The only thing that changes when it is plugged in is the battery is charging. So in answer to your question, you can use anything from 8 amps at 120 volts to 48 amps at 240 volts. But the battery won’t be heated unless the user or the software decides it needs it. Below minus 30 the algorhythm changes a bit from what I understand. But only if it’s plugged in. The coldest we have used ours over the years is about minus 30 so I can’t speak to colder than that. We don’t plug ours in if it’s out in those temps as the cord gets to stiff to put away. The car doesn’t care either way. It takes an extra 5 minutes to warm up and defrost the windows at that temp. We have a garage but unfortunately it is often occupied for projects so it is not always available. Hope that helps. I should have been clearer I wanted to know if the battery was kept warm while plugged in at temperatures down to -37 c (-34 f)--and if so, how much power does it use to do so. I'd have access to level 1 charging. I seem to remember that the Leaf does use energy from the battery bank to keep the bank warm. But really not sure at all
