LichtsinnRV.com - 3 Tests for the Winnebago EKKO AC Run Time

[@temaus]

Good to see both: the most optimistic as well as worst case scenarios.

[@stevetag6572]

Thank you so much for the enormous investment of time you donate to educate your customers. It really is amazing how efficient just one Lithionics Battery at 65 pounds can be.

[@LichtsinnRV]

Happy to help!

[@tkemp4184]

thank you for supplying great information on the ac run times

[@LichtsinnRV]

Our pleasure!

[@mchoney2122]

Come down to South Florida and test it for 9 months of the year and that would be your best test of all. 😃 I love everything about this unit

[@jorgensen8]

Didn't look at the whole video in detail but did you mention how long to recharge a depleted battery from the alternator?

[@LichtsinnRV]

Good afternoon! Thanks for your note... a good rule of thumb is 1-2 hours and will depend upon depletion level, RPM, Highway vs idle etc. Hope this helps!

[@stevenauman]

At what percentage does the battery reserve warning come on?

[@LichtsinnRV]

Good evening! 10% Hope this helps!

[@richardburguillos3118]

Nice… I’ll be having two of the batteries so the shore power through inverter will be splitting its charge onto two batteries this doubling the total charge time for a 100% dual battery charge. Would be nice to show how fast with engine idling. The dedicated alternator I believe will provide 1.6 to 1.7 kW of charge vs the limited 1kW of charge coming from the inverter and that’s at idle. So I feel pretty confident that they f I charge my batteries before sleep on a hot a humid night I should be comfortable till the morning when the system can be recharged, if needed. Thanks again for doing this experiment and sharing the results.

[@xisotopex]

wasnt the solar also recharging the battery during both tests? I know nothing about solar so please excuse my ignorance

[@LichtsinnRV]

Good evening! Thanks for your note. Yes, solar was out in a mix of sun and clouds. Keep in mind when charging lithium that solar is really just a fraction of input to recharge.

[@liberty436]

Thanks for the test . Very informative. Question. Will the generator kick on if the battery runs out. Just a safety net for leaving my dog inside.

[@LichtsinnRV]

Good afternoon! Thank you for your note! We can help with that! We would just add the CumminsOnan auto gen start feature, no problem, which is an inexpensive upgrade!

[@JohnSeitz]

I’d like to know how the departure angle is for the Ekko as I have a steep driveway.

[@LichtsinnRV]

Good afternoon! It is 12 degrees. Hope this helps!

[@busterhyman6633]

Can we up the inverter to say a 3000 watt option and can we add additional Lithionics batteries in the rear storage compartment? I see them on line for $4,500 vs 7K option at the dealer.

[@LichtsinnRV]

Good afternoon Buster! Just give our service team a call at 641.585.3213 to review customization... not sure if the battery cable length would be an issue for them, but we can change the package to two batteries total

[@wyattearp1418]

Thank you, Thanks for sharing.

[@matthewsmith9615]

Purchased an Ekko and it’s my first RV. The AC doesn’t start solely off the battery. I have to first start the generator. Is this normal behavior?

[@LichtsinnRV]

Good morning Matthew! Thank you for your note... this is certainly not normal behavior and I'd recommend you reach out for service... if you'd like to book an appointment with us, just reach out to us at 641.585.3535... we certainly do not discriminate based on where the coach was purchased... we will help any of guest!

[@bobhinley5410]

What I would to know is how long will it run without solar input. For over night sleeping.

[@LichtsinnRV]

Good morning Bob! Thanks for your note... solar input into lithium in this scenario was so little this should be directional for your test of overnight as well, especially as temps drop

[@flip3d]

Can it be configured with 2 lithium batteries AND the generator? Other videos I've seen said you lose the generator if you get the two batteries.

[@LichtsinnRV]

Good afternoon Scott! We can and have done that for our guests. Hope this helps!

[@chefduane3742]

Is it possible to damage a lithium battery by taking it to complete discharge? I know with lead acid and AGM you don't wan't to deep cycle them regularly and avoid complete discharge. Thanks for any response.

[@LichtsinnRV]

Good afternoon! Continuation yes, but there is a reserve level notification to prevent this. Hope this helps!

[@bren_artstudio54]

How about testing using only the generator? Just curious

[@LichtsinnRV]

Good evening! Thanks for your note! The recharge time would be the same off the genset vs being plugged in. The genset operation time would be approximately 48 hours at a minimum if running genset only. Hope this helps!

[@renaissancepoet]

@@LichtsinnRV Am I understanding you correctly? The genset will run the AC for 48 hours? Is that with a full tank of gas? The Facebook EKKO group I belong to has an ongoing debate. Which is better, 1 battery with the gen, or 2 batteries without the gen.

[@LichtsinnRV]

@@renaissancepoet Good morning! Thanks for your note... The primary answer is 50-110 hours off a full tank of fuel, absent using the inverter and battery, so simply genset operation Here’s the math… The EKKO has a 31 gallon fuel tank. The genset runs off the top ¾ of the 31 gallon fuel tank, leaving 23 g available for genset usage. The CumminsOnan 2800i uses .21g per hour at half load, translating into the high end of 110 hours (23 g / .21 g per hour consumption). At full load, so worst case scenario, it pulls .46 g per hour, translating into 50 hours. If you feel like you'll be off grid in very hot conditions, we recommend the standard setup from Winnebago of a single battery and the genset. Then we can add the second battery, so you would have both batteries and the gen. Hope this helps!

[@renaissancepoet]

@@LichtsinnRV Awesome! Thank you for the reply.

[@gosman949]

@@LichtsinnRV the other variable that was not discussed, was the under hood alternator. At idle, how long does it take to recharge the battery? If this is a shorter time than the generator or AC input, then why have the generator option? Just have the one or two batteries and depend on the sun and the under hood alternator to charge the batteries?

A heat index does not register on thermometers, just the real temperature.

[@LichtsinnRV]

Good morning! Thank you for your note… the heat indices we were referencing were from AccuWeather

[@BobtheTraveler-WD8NVN]

Very informative !!

[@thebillbaker4793]

Hello my friend, I like what you’ve done …. very smart. Thank you and as always stay thirsty my friend.

[@LichtsinnRV]

Thank you! Cheers!

[@RicViperskylogs]

Is there a propane delete?

[@LichtsinnRV]

Good afternoon! Thank you for your note! You will need propane for hot water (Truma AquaGo) and heat (Truma VarioHeat)

[@straightarrow6352]

Great information.

[@bcaafd]

Thank you

[@LichtsinnRV]

You're welcome!

[@horizon42q]

Good information

[@Downtime_Garage]

I haven’t seen it mentioned yet but does the battery tray slide out of the compartment to allow easier access to the battery or is it fixed?

[@LichtsinnRV]

Good morning Devin! Thank you for your note... the battery compartment does not need or have a tray, but keep in mind the lithium battery setup is maintenance free.

[@Downtime_Garage]

Thank you for the reply
