Good cell with reasonable price Review by IndrekM80

Rating

I did bought 322 cells last spring and made a 14S23P (48V 73.6Ah) battery out of these. During summertime I rode around 12 000km with that battery. This spring I remeasured the capacity and it gave me 72.1Ah residual.

So, capasity drop is ~2% per year (per ~100 partial cycles)

Not bad!! (Posted on 23-04-21)

Great Cell - Excellent Value Review by ChrisB

I bought 35 of these cells new from NKON. Very fast delivery to Ireland, 2 days.

The Manufacturer states that these cells have a 3200mA capacity and a discharge current of 10 Amps.

I tested 5 cells at random using a SKYRC MC3000 charger with PC graphical software to display charge and discharge characteristics.

A full discharge and recharge cycle was completed for each cell with a 20 minute rest performed in-between..

Charging was done at 1 Amp and discharging at 0.5 Amp.
For this test the cell was charged to 4.2v and discharging was stopped when the cell reached 3.1 volt.

Each cell gave approximately 11.36 to 11.77 watts total power under discharge - this is a strong result.

All cells showed internal resistance of between 36 and 42 mili-ohms - These numbers are consistent with this type of cell.

Discharge curve with a 0.5 Amp load was flat and consistent - this is a good result.

Each cell was found to have between 3097 and 3147 mA capacity. The rated capacity of 3200 mA, may well be available if the cell is discharged down to 2.8 volts. But this is not recommended practice with a lithium Ion cell. These figures are close enough to the manufacturers stated capacity.

The cells never went above 33 Deg Centigrade and the ambient room temperature was 21 DegC. So, little if any noticeable increase in temperature when charging or discharging

Overall impression: These cells provide consistent current between 4.0 volts and 3.1 volts. There is very little usable power outside this voltage range.

The cost per watt of power makes these cells very cost effective and perhaps the most economical way to get the most power for your money.

The Panasonic brand is well regarded and has a reputation for high quality cell manufacture.

Verdict:
Excellent battery with a large and usable capacity of 3200 mA and a high discharge rate of 10Amps.

Excellent choice for e-bikes, energy storage and power tools but not recommended for use in vape devices.

Best charge/price ratio Review by Szilárd

I ordered 30 of these cells for my battery pack. When they arrived, I measured the voltage. All of them were exactly at 3,51 volts. That's what you call uniformity. These cells are excellently built and they hold their charges quite well in low temperatures. This is the most charge you can get for your money. Worth buying. (Posted on 03-03-19)

Excellent for ebikes, great value Review by Scott Silence Speed diy ebike

Rating

I have used 65 of these cells to build a 13s5p battery for my fast commuter ebike with great results.
Range is excellent with a small high speed hub motor and 350w controller. Voltage sag is less than 2v during acceleration and I average between 30 and 35 km/h with topspeed well over 40.
There may be slightly better cells, but this one is very cost effective.
I expect very good cycle life because of the NCA chemistry, and I only charge to 4.05v (~80%) to further improve this. (Posted on 13-02-19)
