RE: 6 v GC batteries versus 12 v lithium deep cycle batteries

I don't know if the op left or just didn't come back after the they posted it in another section of the board before it was moved here. 5/14 posted @ 1056, 7 replies that day 5/15 19 replies 5/16 30 replies Today 6 Not one follow up question and maybe they got the answer they needed? If not as the orignal poster with questions and the thread starts to go astray from your question that might not be answered put the thread back on track to question asked or a new question that might of arised from the responses.

RE: suggestions for screen door with dog

Get a piece of plexiglass. Easily cut to size and screw into door.

RE: 6 v GC batteries versus 12 v lithium deep cycle batteries

Some folks give to much worry into the bms, it's a pretty straight foward protection of the batteries operations. These threads at times do seem to wander but if your can separate the wheat from the chaff the nuggets of info are there. :)

RE: 6 v GC batteries versus 12 v lithium deep cycle batteries

Itinerant1, in your opinion, is jaycocreek seeing balancing on his smart shunt from what he describes or not? Is that the same as what 3 tons sees? (I can't see his posts) If so, why wouldn't that show on any monitor such as the Trimetric? It was probably balancing during the 14.4/ 13.6 cycles but it would of happened at the higher voltage period but that is not the bms balancing, that's the charger doing what it was programmed to do? "If" the bms was causing the shutdown and restarting I would guess the cells certainly have runners that the passive balancing can't keep up with. Without the ability to see individual cell voltages it's just my guess what someone else's batteries are doing. You do understand what passive balancing or active balancing is or does, most dropins will use passive just because it's cheaper. My cells use passive with the sense boards (bms component) that start balancing when a cell reaches 3.55v, the sense boards will draw 0.5A until the voltage has dropped below 3.55V. During this process it's normal for some cells to balance more than others and some cells to rarely balance.

RE: 6 v GC batteries versus 12 v lithium deep cycle batteries

The point being is best not give advice on something you don't understand or just guessing at. This is the regurgitation of bad info getting past as gospel. ;) You can argue with Trojan then, since you seem to know more than they do. "Balancing is performed when a parallel group of cells reaches a specified threshold voltage corresponding to almost 100% state-of-charge (SOC). At that point, the highest-charged cells “bleed down” a small amount to enable the remaining groups of cells to “catch up.” ( ISTR 3 tons was able to see that "bleed down" on his monitor, but others will have to confirm) "At a voltage threshold slightly higher than the balancing point, a current interrupting device (contactor or FET array) will open, stopping any charging current from flowing..... " Even after the charger is unplugged, the battery may not be ready for use until it is allowed to balance for approximately 10 minutes..... Note: Once a set of batteries have achieved a balanced condition, they should remain balanced through normal use and charging. In order to keep batteries in balance and avoid over-discharge, ***** ensure that batteries not in storage receive a full charge weekly*** " https://www.trojanbattery.com/pdf/Trillium_UsersGuide.pdf What you stated in the post I responded to was this " I think the balancing can be observed on the Trimetric." now read my response again. Even with the dropins that don't show individual cell voltages how do you know its truly taking place when all you see is pack voltages? Copying and pasting shows your abailty to master computer functions but do you understand what you're pasting?

RE: 6 v GC batteries versus 12 v lithium deep cycle batteries

You wouldn't know cell balancing is happening off a monitor that is showing just pack voltage other than it happens at x-voltage, bms's use individual cell voltages not pack voltages. "If" you can see individual cell voltages you would be able to see the runners that should slow down after they reach the balancing voltage while the slower cells catch-up.

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.
