Another feature: after a year of use, capacity of LiFePO4 decreases less quickly than the capacity of Li-Ion, so, after a year you are left with roughly the same energy density per mass / volume as with LiFePO4. And the capacity of Li-Ion battery is decreasing still more quickly...

[@philc.9280]

I have both and never let either one drop below 60% so I'm hoping to get at least double or triple the cycles they are advertising. None of them have ever gone down to zero yet. I'm expecting at least ten or more years out of my Power Queen LifePo4 200 ah batteries

[@Bulambo287]

@@philc.9280 you're right

[@cjhan47]

the operation range for LiFePO4 batterys is down to 20% per cycle so it would seem you might just be wasting capacity And I'm not sure doing that extends the life of the battery.

[@absolutium]

​@@philc.9280That's helping no one.. the ideal state of Lithium based batteries goes from 30% to 85%.

[@superdau]

To avoid confusion: *LiFePo are Li-ion batteries.* "Li-ion vs. LiFePo" is only a colloquial distinction, but won't help you when looking for technical or scientific information. It is pretty much the same as the other often used colloquial distinction between "Lipo and Li-ion", labels which were wrongly assigned to pouch cells vs. cylindrical cells (the contents are pretty much the same). Li-ion is the name of all cells that use Lithium to store energy, which LiFePo do as well. The difference is that the cathode material contains iron-phosphate instead of the usual cobalt/nickel/manganese oxides. The rest is pretty much the same.

[@PiDsPagePrototypes]

Pronunciation makes ion vs Iron a pain, I've found calling them "Lithium Ferrous Phosphate" when selling them matches the lettering on the side better for customers to understand easily.

[@ernanimartins]

@@PiDsPagePrototypes Is the charging method is different? I am used to Lipo but not LiFePo.

[@PiDsPagePrototypes]

@@ernanimartins LiPo can accept a higher input current the LiFePo, and output much higher currents, and the voltage per cell is different 3.7v for LiIon vs 3.2v for LiFePo. This is why LiFePo is an easy replacement for AGM and Sealed Lead - similar charge/discharge and voltage per cell. Most commercially available chargers now have modes for Lead and for LiFePo.

Ok, so I just saw the video on a spot welder. Question is, can you power the welder with something other than a LiPO battery pack? It would be nice to not have to invest in another type of battery and charger, plus the Lipo's are more dangerous and that is one of the things that the iron phosphate are trying to avoid. If there is no other option, do you have a charger for the lipo pack that you recommend?

[@boblogan6701]

I wish to thank you for combining theory and practical data in such a clear and concise manner for the newbie. I have a request.... being totally new to the EV world (but with decades of computer technology involving seldom connected and emergency backup power needs)... I understand the compromises involved with such technology... however I searched long and hard for any coverage of Torque/Power outside the context of speed. I am not seeking speed but torque and your explanations have helped greatly. So my particular build will be require addressing my rather small radius of travel (local errands/shopping) over some very hilling terrain... STEEP hills. As a retired senior citizen 3 wheelers make sense, and since I shop exclusively at Big and Tall clothing stores a heavy steel frame makes sense... I also am considering FAT tires feeling not only a more comfortable ride but the increased roadway contact will maximize power transfer into forward progress... (???) SO MY REQUEST of you... do these design decisions make sense? Total weight factor will be plugged in at 500 lbs MAX... bike, electronics, rider and packages (figure weight of a gallon of milk, 12 pack of cola... $75 of fresh meat, produce and dairy can get hefty.) Finally with the trike frame and power train (as I understand it) ... we have a power driven axle rather than power driven hub concept (which is why all kits I have seen tackle by front wheel hub motors)... my concept will actually attach a second sprocket to that rear axle... giving (hopefully) max power delivery to rear of vehicle. Second option would be to put the spoke on the rear idle wheel and effectively have both wheels under power (weird kind of power assist). So in short my request is can you address trikes as ebike conversions... or off the shelf offerings? Finally I will impose upon your good nature and ask for your opinions and comments on my 'over loaded' e-bike concept.

My experience with LFP is very good, as my application with my boat, using in a Minn Kota ulterra trolling motor. When I owned a boat in the past, in that place near China and they can customize an LFP 36v 75AH battery with all the protection board build-in, including high discharge and charge capability. I am happy that the manufacture has done all my requirement and it just works so well until I sold my boat leaving that place, the battery still goes strong from the new owner of my boat. The battery on the boat requires safety at first no other argument. The reason is if the battery goes wrong and cause fire or even explodes it just ignited the petrol tank in the boat. A 23foot long offshore fishing boat we would bring over 300 litres of petrol full onboard, so imagine what happens if there is on fire or explode will do after all. The 36v 75ah LFP battery just weighs around 15-20kg, I haven't weighed it very clear just by feel, so it still much lighter than the traditional marine deep cycle battery set of 3 x 12v and very much shorter life-span and discharge volume even it fully charged! Oh yes, if you using the marine deep cycle battery, it even more expensive than that LFP, and every time battery is out, you need to charge them one by one compare to the LFP battery just a single plug and done! I am settling in another country, I think after all of the mess I will come back on the water, and using the LFP battery with no hesitation.

Just the min/max voltage differences stated in the video. You'll have to pay attention to chemistry specs on BMS, chargers, etc. Different LiFePO4 cells are manufactured differently.

How do you choose the BMS for a 36V system? How do you know if 3 separate 4S batteries is better then a fully built 36V ish.

[@Tron-Jockey]

Great information although if you're going to mention the LiFePo4's charge cycle advantage then you should probably put that into context, specifically in terms of the depth of those charge cycles. I'm assuming that your discussion concerning the number of charge cycles each chemistry can reach was for "full" charges (nearly 0% to nearly 100%) for each charge cycle. You didn't specify so we're left to guess. I feel this is important since it greatly affects the number of charge cycles each chemistry can endure. It is true that, all conditions and circumstances being equal, generally speaking LiFePo4 will accept many more charge cycles than Li-ion. However, under the right conditions most flavors of Li-ion will last considerably longer than 800 as well. Owners of EV's have learned that keeping their car's traction battery between 50% and 90% can greatly increase it's life span. This of course applies to LiFePo4 as well. Charge Cycles: DoD NMC LiPO4 100% ~300 ~600 80% ~400 ~900 60% ~600 ~1,500 40% ~1,000 ~3,000 20% ~2,000 ~9,000 10% ~6,000 ~15,000

I have a question about building an ebike, I have a 2019 trek duelsport 3, can you please help me find a kit that will fit my bike I’m ok with rear hub or center motor. I am mechanically able but would prefer something that you may know of that will not only look good but that installation won’t be a difficult challenge.
