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...
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
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.
@@philc.9280 Damn, I abused my Lead Acid battery until my inverter shutdown, I was so ignorant reading couple labels here and there, I learned a lot last two years watching TH-cam videos.
i've been using a LiFePo4 battery on my modded Lectric XP for a short while now, and super happy with it. i switched to this tech for the safety aspect
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.
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 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 add up to a similar voltages for the battery as a whole - IIRC 6 cells for Lead vs 4 cells for LiFePo for "12v battery". Most commercially available chargers now have modes for Lead and for LiFePo.
LiFePO4 are being used in commercial sold electric vehicles. Everything from semi tractors for 50t gross weight to Tesla (they use LiFePO4 in the small battery version).
I recently purchased DIY rear Wheel Motor kit to install on a mountain bike that I built. I'm saving money now for batteries but have honestly been pretty confused about what I'm looking for. This video helped answer some of the questions that I had. I may try the LiFePO4 route. I look forward to your battery build!
I like the idea of increased recharge cycles of the LifePo4 batteries. I love this improving technology, and the amazing new products I am seeing! I want a hover skateboard one day lol
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.
Neat to see Iron phosphates here. Odd question Micha; I've felt like eBike and small vehicles should go for the Iron Phosphates instead of Lithium ions for those reasons; that their stability in temperatures (since most bikes won't have radiators or temperature controls) and their ability to be deep-discharged without damage makes them a better choice at the end of a build. What do you think?
Bit confused about your terminology. I thought it was something like: there are many types of Lithium Ion battery chemistries like NMC (Lithium Nickel Manganese Cobalt Oxide) used in power tools and eBikes, LFP (Lithium Iron Phosphate) primarily used as lead-acid drop-in replacements and LMO (Lithium Manganese Oxide) often used in electric vehicles. Lithium Polymer batteries are another subtype of Lithium Ion technology, the difference being in the very thin mechanical structure of the separator and electrolyte, and most often found in digital devices such as mobile phones, laptops etc. My point being that LiFePO4 is just another form of Li-ion. Have I misunderstood?
@General Smedley Butler Yeah, cool, thought as much. Thought I was going a bit crazy with the "Li-ion v LiFePO4" comparison. What he probably meant to say was "NMC v LFP", or whatever chemistry he was comparing to LFP. _edit: typo_
Great video. We are looking at buying a PV solar system* and concerned about the fire risk of using the various Lithium battery backups. The LiPePO4 backups sound much better. (*We are not ready to make or own backup batteries...yet!)
I'm going to be doing the same thing but with only 40, it would be nice to know how your build turns out in comparison as far as battery output to see if there more or less the same to see what the capacities are.
That's going to be a pretty decent set ups, it sounds like you're going to do a solar setup. I'm making a portable solar generator. My setup is going to be a 12.8v nominal as well but only 50Ah and 620wh as my needs aren't that much at the moment, I'm new in the batteries and want to make a battery pack with a safe chemistry.
@@mindovermatter3988 ya, I'm basically making a portable power station that will be charged with solar through an mppt charge controller, and use a solar tracking system to tilt the panels. The battery, bms, mppt charge controller, and the inverter will be in one big portable unit, and will just plug into the solar wiring, and charge under the panels.
inquiring minds want to know. I think the difficulties Micah could be facing with that build are really making similar builds look less and less feasible for the average joe. Much easier to start with a purpose built frame like the one being featured of Capt Codswallops channel
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.
Great video, I built my bike with a 40ah LiFePo4 and do not regret the added cost. Another plus environmentally, these batteries do not use cobalt; a costly rare earth element.
@@PiDsPagePrototypes Well the "rare earth elements" as in the lanthanide series are all metals too. And cobalt is pretty rare making up just 0.0001 percent of the crust. The phrase "rare earth mineral" is not defined chemically. One would assume it's any mineral that contains a lanthanide element. Cobalt is pretty rare it's an element found in the earth. Only in the strictest chemical sense is his use wrong.
@@PiDsPagePrototypes What? ~ 95 of the 118 elements on the periodic table are metals. So 80% of all elements are metals. Cobalt is an element. Being a metal does not preclude it from being an element. Gold, silver, copper, lead, tin, iron, bismuth, sodium, potassium, calcium, mercury, tungsten, titanium, lithium, aluminum, arsenic and almost 80 other ELEMENTS are all metals. The only metals that aren't elements are alloys which are mixtures of elements.
Yep same, i would love to see a continuation video on your retro E-Motobike build in the near future. I still think its a cool concept that needs to be put on back on the streets. 👍👌😊🚴
It is interesting to hear these are more expensive. Supposedly car manufacturers are switching to LFP due to a lower cost. I am not sure what the difference is.
Thank you for the information, I am looking for a replacement for my rv battery and was looking into lifepO4 batteries. You helped me make my decision.
Any followup video to the 32650/32700 cells you were spot welding? I have been using them to make small solar generators, but would love to see you make an ebike or something out of them? What would REALLY be cool is a Vruzend type kit for them.
Thanks so much Micah! I bought a bunch of LifePO4 cells and am hoping to start building some different systems. I have not been able to find any accessories however. For example: which nickel strips, which charger/tester, which spot welder, etc. I look forward to your upcoming video on the build, however, if you could pass along any specific info that would be great. Thanks again
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?
I didn't know you were the author of those books!!! LOL! I bought the battery and solar book off Amazon and was just here because I wanted to see your take on the battery difference. Lol who knew!!! Good job on everything Mr. Toll!
LiFePO4 *is* li-ion. Just like the other common cathodes NMC, LMO, LCO and NCA. LFP is more stable structure which allow more impurities and cheaper manufacturing process. Now most of the base patents will be void for LFP so we can expect significant price drop in 2023. We will probably have 10.000 more manufacturers by then too so the BMS role will be crucial to detect failures well ahead of accidents in DIY projects.
Interesting info on the two types of batteries. It'll be interesting to see if companies will start to adopt LiFePO4 batteries for e-bikes and e-motorcycles in the near future.
