RE: Honda EU2000i at high altitude

It's such an easy job to change the jet and at the same time clean the carburetor, why not just take 30 minute's and do it so the generator runs optimally than "it should run ok" and possibly do it in the field.

RE: Charging LFP battery from AC-DC unit

Dropins are tough for advice short of follow what the builder recommends for charging/ discharging. LFP all follow the same characteristics just the guts of the dropins differ.

RE: Charge wizard with Lithium upgrade to Converter charger?

This has been covered already. BMS is there (or should be) as a last line of protection not the first. "Float" if used in a daily cycling of the batteries won't hurt it but if your going to float them at storage for long periods of time then it could shorten the battery life.

RE: Charge wizard with Lithium upgrade to Converter charger?

Or they just wanted to hurry and get on the new band wagon for profits. Fix it/ update it down the road. Buyer beware of the sales pitch, atleast some folks are catching on to the charging requirements but many still are trusting souls lost in the forest.

RE: Transferring fresh water when dry camping

Here's a thread of the details I posted elsewhere. Before upgrading to the larger bladder. 20 minutes 60 gallons timed. https://www.ford-trucks.com/forums/1480651-water-bladder-tansfer-setup.html#post17029807 Link after upgrading. https://www.ford-trucks.com/forums/1440415-national-forest-trip-14.html?highlight=Seaflo#post18634329

RE: Transferring fresh water when dry camping

I use a bladder. This one can hold up to 60 gallons and when not in use folds up and takes little room. https://i.imgur.com/cYfbpEbl.jpg

RE: Basics of Lithium conversion... I'm lost!

If the color of the sky is blue and someone insist it's green let them call it green if it makes them feel better. These lfp threads are getting old with so many done already showing proof of the attributes and myths busted or proven wrong, yet more proof is wanted. I'm just going to lurk and read these threads for now on while using my lfps and I guess doing everthing wrong now for 5 years everyday with over 1,600 cycles. Enjoy.

RE: Basics of Lithium conversion... I'm lost!

There are the haves and the have nots. It's amazing that the have nots know so much more than the haves using them everday. Most of the debates or points of contentions seem to include "best cycle life" or "long life". What is the length of time for the "best cycle life" to be accomplished? Using my manufacturer claimed specs for 100ah battery. Cycle Life : >2000 (80% DOD) or (160,000ah); >3000 (70% DOD) or (210,000ah) If you're buying them for "best cycle life" use less of the available stored energy. 60% DOD must really stretch the cycle life out. But than I've read you can't trust the SOC monitors so are we really getting what is claimed. ;)

RE: LiFePo4 vs Lead Acid...Some points of interest.

Browsing Marine how to site... I thought this was an interesting "test" using .2c & .4c charge rate on a Lifeline GPL-31T battery. https://marinehowto.com/how-fast-can-an-agm-battery-be-charged/ "This battery only saw an approx 12 minute difference in a 5.5hour charge period but yes it did charge “faster” at .4C than it did at .2C." "SUMMARY: In this portion of the testing 50% to 100% SOC, on this AGM battery, the difference between a .4C and a .2C charge rate, netted a 12 minute total charge time difference." ;)

RE: LFP on Shore Power with Inverter/charger?

And just to head of the next question, here is similar data for 120Ah CALB prismatic cells - these (or similar) are what most folks are using for their DIY lithium packs: https://www.evlithium.com/Upfile/2017/9/1/2017090148339777.png width=600 Almost looks like someone just drew with colored markers. ;) Here are GBS 100ah cells charge/ discharge curves. https://i.imgur.com/UlDOpRhl.jpg https://i.imgur.com/Ttnbvz7l.jpg You look at enough of the lfp charge/ discharge graphs they all look very similar.

RE: LFP on Shore Power with Inverter/charger?

Interesting numbers! Looks like average 65 amps solar to the batts for 5 hrs plus any for loads so 65/500 = 0.13C Then with a/c on you were also running about 15 DC amps worth of other loads. If I got that right. That's pretty close, the solar is producing near 70-75ah now from 11:00-13:00. 60-65ah is about the average charge rate. 60-65% SoC seems to be the good cut off using the a/c and leaving plenty of power for dinner microwave use, evening tv/dvds, humidifier which runs 24/7, lights and then morning coffeemaker/ microwave use ending near 35% SoC +/- or 65% DoD depending on how you look at it. Using like this is faily gently on the batteries with fractional "c" use charging/ discharging. Edit: last glance last night was 21:30 at 54% SoC. Now after making 1st pot of coffee SoC 37% SoC, batteries @ 13.11v, Inverting @ 13v with -11a loads. Sun coming over the hills, it's going to be another great day. ;)

RE: LFP on Shore Power with Inverter/charger?

I'll help bring it back around some to LFP on solar power with inverter/ charger. ;) Started this morning after breakfast (09:00) at 34% SoC by 14:00 at 99% SoC, charged by solar. At 15:20+/- turned the air conditioner unit on for a 2 hour cooldown. Solar was contributing at the start 534 watts, at the end 223 watts. https://i.imgur.com/Chr7ChUl.jpg Good enough for a couple hours when the sun finally dropped low enough and a breeze took over cooling. :)

RE: LFP on Shore Power with Inverter/charger?

I'll be interested in the high draw items and length of time before the battery voltage/ inverter tags out with Si02.;

RE: LiFePo4 vs Lead Acid...Some points of interest.

There is nothing here that is specific to lithium in any way. Unlike lead the 'operating SOC range' doesn't matter at all for lithium, you can bounce between 0% - 100%, 0% - 50%, 30 - 80%, all you need is the capacity. Well several folks on here have said they plan to stay in mid-range. Itinerant1 has warned to stay between the knees and that he usually stays above 35% Doesn't change anything. You pick your own SOC range and go from there. I don't go out of my way and use the mid range area it just happens 35% SOC seems were my use gets down to before it starts charging (1,280w solar goes along way even in winter) Many times over the years I've been in the 25% SOC range, that's always morning after making 2 pots of coffee (12c Mr coffee) and using the microwave for 5 minutes making breakfast. Edit: 55-60% is my evening time SOC during winter months (mid Nov, Dec, early Jan) when I'll run the gen for an hour or so for a hold over charge. So morning time after the mentioned above morning routine they'll be enough power. I don't skimp on my power use.

RE: LiFePo4 vs Lead Acid...Some points of interest.

I could revise the former test as: Cycle the LFP at 10% - 50% and the FLA at 10% - 50%. Do this until the FLA dies. What do you believe would happen to the FLA if it were reharged at 10% - 50%. Quick death? I like this test. We can even spot the FLA 500 cycles. ;)

RE: LFP on Shore Power with Inverter/charger?

The best part of this was last spring when a storm blew through and power was out for a couple of days, we didn't even know it till a couple hours later when I went outside to check out the damage and the campground owner came by to apologize for the power lost and not knowing when it would return. It made no difference for us because we always fill the water tank and it a seamless unnoticed event when going from 120v to 12v inverting power and solar to help with the heavy lifting. ;)

RE: LFP on Shore Power with Inverter/charger?

This is what I do.... right, wrong or indifferent. I set my inverter (hybrid) to loadshare 30a or 50a depending on the power source. I turn off the charger but leave my solar on to charge if needed so the inverter is passing through power, powering everything 120v but the 12v loads are carried by the batteries. When I was doing this it was colder weather so the furnace and misc 12v loads would use roughly 10-15% DoD (50-75ah) solar would top them off and float at 13.6v. This was last spring for a couple months during covid first started and didn't want to stay in hotels for work. Also did this way 5 years ago before doing the boondocking fulltime. Lot of cycles of use with heavy draw items everyday. Past 2 weeks with the heat (90-100f) kicking here in AZ I've been spliting run time of the generator, batteries & solar using the air conditioner. When air conditioner, tv, humidifier and other inverting loads there will be 2-3 hours of 100-175ah inverting, stopping at 60% SOC then do the gen for air conditioner for awhile longer but not using the gen to charge the batteries. By the time morning coffeemaker, microwave use is finished SOC is 40-45% and solar will charge back up by 2pm roughly when I switch the air conditioner back to batteries/ solsr and do it over again. Today started moving north so shouldn't have to do this for a while again. :)
