Very nice of you for making such good test and review. I just bought the same cells for a neighbor's drilling machine and I wondered how good they will stood. Make more of this videos. Thanks!
I do not understand why there is so little talk of internal resistance and therefore voltage sag. It has been a big surprise to me when I put 214 of Panasonic NCR18650A cells into my scooter and experienced voltage sag for the first time. Still to this day, I need to basically "dance" with the throttle, when it reaches 50% capacity. Internal Resistance needs to be more widely known and considered. Thank you otherwise for this nice review of the cell.
Thank you for the fine video! I notice with my BTC3400 charger it does the same thing testing. Left slot is lowest, right slot is highest. I think the batteries are all the same, but the charger just measures each slot a bit differently left to right.
Great testing, thorough and helpful. Thank you I was looking for the update video you mentioned you were going to make in the comments. Is it not uploaded yet or am I missing it somehow? I'm very interested in how these batteries have been performing as the battery pack I'm looking at comes with these cells. Any info you could give me as a follow up? Thanks!
Thanks for the vid…. I got a link from a review that was maybe yours ?? Would you recommend these to build an ebike battery with. 14s6p ? Great review…. I am a total noob that’s had an intense 4 day ebike building course…. Self taught on TH-cam & Google. My ebike controller max current is 40amps. So 6 of these in parallel would give me 60a. In your opinion (ebike for my wife, so not much hard riding) would these be suffice for my build ? Thanks in advance for any replies 👍
These are pretty decent cells if you can get them cheap...I got them for like $1.99 and I think at that price they are worth it....but otherwise I would search for some 3500mAh cells Samsung 35E 8A Sanyo NCR18650GA 10A LG MJ1 (The MH1 3200mAh is another good cell) 10A Panasonic 18650BD is only 3200mAh but is also a 10A cell If you can get any of those for $4 that would be better. $5 is ok....I'm cheap and might keep searching but thats the normal price for new 3500mAh cells.
@@ericklein5097 $2.00 is very cheap!! They are $3.00 now on 18650batterystore now, and I thought that was a great price. I found your video looking for a review before I bought. I only use them for small flashlights and maybe power banks. I like them for my use.
Why did you do the fast test? The proper test to do is NOR test. I'm pretty sure the FAST test is just measuring charge mAh which is not the number you care about. I think the program does a discharge first then charge. NOR test does charge, discharge (records mAh) and charge. Your DL24 connection to the battery holder is kind of defeating the purpose of 4 wire measurement. The V+ and V= leads need to measure directly at the cell terminals. Any length of wire that has current running through it (the brown and blue) is going to be affected....thats why the voltage was 3.4V at 10A. It should be 3.6'ish
Bad TEst ! Give us a video for the result of a full discharge test to 1A, 2A, 3A, 5A, 10A and the time for the full discharge and mainly the mAh for each ampere discharge ! That would have been a great test and a great review for this brand ! To resume your video it is just a lazy test made in 5mn...

For now i don't have device for IR other than my charger...

Tnx
I have put the batteries in my electric scooter, here you can see how they perform

Thanks brother for testing, hows this brand cells performing so far?
I have them in my electric scooter and they perform great. I will put video soon...
