Sure, but can they be purchased for a bit over $4 a pop?
Free shipping. Cost was $12 all in. $4 a pop for 50G performance, I’ll take it. But Mooch cautioned that there’s a wide variance in their performance, I guess depending on their salvage history.
What threw me a curve with these cells was their middle voltage output—I stumbled upon it by chance — I had several at storage voltage ( 3.82v) and did some amperage test in a single cell quad light (fet driver) — the output in amperage and lumens were not that far off from a 40T that was around 4.08 v —- after doing Full charge test and around 80 % charge test I realized the Model 3 outperformed the 40T in the below 3.95 v range — also these cells when doing a capacity test hold a majority of their capacity above 3.45 volts
Any idea if these would be genuine Tesla Model 3 21700? (one of them indicates “LDTSL ZS48T”)
Based on my capacity test results (using SkyRC MC3000, charge to 4.20v, discharge down to 2.50v at –0.75A discharge current), I get around 4700+mAh capacity on them.
AC IR measures to around 11.9mOhms at around 3.70v (shipped voltage is around 3.70v)
Looks like Model 3 to me —The 3 marks on the neg end —— I haven’t discharged that low —my Opus stop at 2.8/2.9 v
Just bough three from techdirectclub. Shipping was free.
where did you buy it and how much?
I just ordered 3 from Tech Direct Club for $11.99 & FREE shipping.
They were cheaper at Battery Hookup , $9.75 for 3… BUT the only shipping option was FedEx for $16.24 
A bit steep when only ordering three… :money_mouth_face: :person_facepalming: 
I ended up getting 100 from batteryhookup. Anyone deal woth these sellers before and what their experiences were? Also is there a bug difference between the 4800 and 5000 or are they essentially the same?
I’ve ordered from batteryhookup a few times. I haven’t had any problems at all
I’ve dealt with Battery Hookup on several occasions —Some good Some bad —- They always make good on my purchases —- I test everything I buy from sellers when it comes to mah and lumens ——lots of inflated numbers flying around —— Of the 150 Tesla cells I purchased from Big Battery ( Tech Direct Club / same guy) most cells tested 4750-4850 with a few hitting in the 4900s —- I also had a few in the 4600s
Your capacity test numbers also match the LDTSL 21700 or Model 3 21700 batteries I got, anywhere from around 4600+ to 4900+ mAh, but most are in the 4700-4800+ mAh.
The aforementioned (LDTSL or Model 3 21700) 21700 batteries sourced from a local seller in our country, whether the battery is labeled “4800mAh” or “5000mAh” or doesn’t have a capacity mAh label…
Very pleased with the shipping time from Tech Direct Club
First Class was FREE & 3 days from West coast to East coast. 
They do have quick shipping, but mine were shipped a bit Unsafe
The 3 cells were open in the box with some bubble wrap. The cells weren’t separated. Just seems like an accident waiting to happen .
Yeah, that is what I kinda thought also at first. But it seemed to have worked out OK & since they are flat tops, little chance of bad things happening I think.
I may order a few more. 
I bought 3 that were shipped in a plastic package but the bubble wrap they were in wasn’t taped so the batteries spilled into the plastic package. So there was just 5 mil or so of plastic protecting the batteries from all the bumps, jarring, etc that the batteries went through during shipping. They could have taped the bubble wrap but I guess 10 seconds of extra work was too much for them to do.
My 2 year old grand-daughter could have done a better job wrapping the batteries up for shipping.
Yeah, mine were in a rectangular box sandwiched between two layers of big bubble wrap. Thankfully, it was a tight fit when the box was closed, so they were just sitting there in the box safe & sound.
If the fit had been loose, that would have sucked. 
Ordered me some as well. Shipped loose in a box with bubble wrap lol. Oh well.
all 3 came at 3.7v.
Ordered 6 more Tuesday night 18 May about 2300 hours. They arrived yesterday 21 May about 1300 hours.
That is fast shipping & delivery.
The packing on this order left a lot to be desired. Basically just 6 batteries loose in the box. 
But they seem no worse for wear.
