- All that work, all that time... Gone!!!
Yes, you've guessed it, like so many others, I've made the switch over the LiFePo (Lithium Iron Phosphate) from 18650 chemistry. It took a few days to make the decision but once I began advertising the cells they all sold within 1 week! Can you believe it!? There was nearly 3000 tested cells and they went in a heartbeat - amazing.

Thanks all, stay safe, lots more to come and have a wonderful holiday season!
Psst... I've created a discord server that nobody knows about yet... Come and say hello and lets have a chat lol:

See you in there! Take it as a reward for reading the description ;-)
The Lithium iron phosphate chemistry is safer too. Rather than having a raging inferno with 18650's, you simply just get smoke with Lifepo4's.
Let hope we never have to test it :-)
I did the exact same thing in September. Sold 20KWh of 18650 and purchased rack mount LiPo. The happiest person afterward... My wife. Walks around the house saying things like, "I'm no longer a battery widow!"😲
Haha, my wife says the same...
Ya. Time is expensive nowadays. The less work included in building and maintaining a battery should also count to the cost. Not only the actual cost of the cells.
Yeah, 32 cells are a lot easier to maintain than 3200! :-)
Pity for not being persistent.. the 18650 would have been the better choice in my mind..
I still have a couple of thousand cells in the garage, we'll see what happens ;-)
Right on, it was just a matter of time. Stay safe Cheers
Haha yeah, I think you're right, you to!
Good plan. I think most of us are heading that way :)
I think you might be right
I'm right on that tipping point but I keep mine around since most of what I have are LG MJ1 cells so.....considering I pulled mine from lightly used E-Bike packs and they all test above 3200mah I think I might keep them for powerbanks and other smaller battery packs for camping/off roading related activities. My brother just bought a 12V compressor for his truck and I don't see him permanently mounting it so it might be nice for him to have a couple 12V 50Ah lithium ion batteries. No need to even turn on the truck and makes it a lot easier to help other people put some air in their tires when you don't have to pop their hood and realize they have some funky battery setup thats a pain to get at (looking at you BMW)
I'm torn on doing the 16 280Ah raw cells from Alibaba (price seems to be just under $2000) or Trophy batteries.
Yeah, I paid just over 2000USD for mine. If you've got good cells and a good bms you'll be fine with the 18650s I'm sure. I still have lots of 18650 packs to process and I'll use them to build portable power packs as well
Yes you’ve definitely done the right thing ;)
Good stuff :-)
You did the Right thing selling all your 18650's Sir. I'm sick too testing them from almost 6months :( i didn't cared about the price when I'm buying but later i realised I spent so much money on them, until we make them something useful worthy right?
and I'm so excited on your next video with those blue bricks Haha nice video btw 👍
Haha blue bricks :-) It feels great to swap from thousands of cells to just 16!
Love the content. For the past 4 year I’ve harvested 18650 they are small fiddly and now have better competition out there. There are however a lot of products that still run on 18650. I repair makita drill batteries and make usb chargers that take up to x16 bought direct from eBay. Would love to see you compare the li Poe with the 18650 in build videos
Hi Gary! Yeah I'll still be building 18650 packs so I'll be able to compare. Are you selling repaired marital batteries, I hear there's good money in that?
@@TheKilowattChallenge not selling them just for myself. Making a lot of mistakes, their bms likes chemically identical cells. But that’s how we learn right.? Have a larger powerwall in progress but it’s all about the balancing. Anyways the future is electric. Keep the channel going you are a great presenter. Hny and stay safe.
You will be okay, am about to order 100+ 280K cells from Ali : )
No more fire risk from the cells ;)
100+???? Seriously?
Daren, is it possible for you give me some of the leftover 18650(I don't mind the heater, CID Issue cells) i will pay for the shipping.
I only have good cells left which I'm going to sell I'm afraid
@@TheKilowattChallenge so how much are you willing to sale.. I hope you will bring the price down for me due to shipping cost 😀.
Once they're all tested, they'll be around 1euro each depending on capacity
@@TheKilowattChallenge wow 😔, about #1,430 to 1 euro.. no way for me then 😞
but Darren, you havent't even BUILD one Li-Io storage system in those 2 years? Therefore, you didn't have any benefits from it? How long are you willing to wait any longer to reduce your energy costs?
As long as it takes for me to install the safest and most robust system possible ;-)
@@TheKilowattChallenge safety is a biggy with batteries
I get all my recycled 18650 for free I dont mind processing and i prefer building my own packs and just love it I have a some lifepo4 cells and built a small system but I honestly prefer Nmc just my opinion who am 😂
Wow you get them for free! That's awesome.
So you’ve seen sense and purchased some 320ah lifepo4 cells and you running a seplos BMS now ?? Iv only watched the first 3mins so far
Funny you should say that, video coming out soon :-D
Where are you selling them? ebay?
Actually, most of them have sold selling on Marketplace on Facebook!
Did you use Amy from Docan?
I don't want to say until I know for sure the cells are genuine, grade A and have the advertised capacity. I would hate for someone to lose money upon my advice ;-)
@@TheKilowattChallenge you’ve got an RC3563, right? If you don’t then I’m completely making up that video I’m my head. IR and hitting the cells with massive loads are really the only way verify you got grade A. I know people rip on Sun Fun Kits but the owner has some good videos on here. He puts cells under a 100-150 amp load and the garbage cells plummet in voltage while the Grade A hold their own around 3.29
Or you could just buy a megacell charger ;-)
