Excellent Review by Razvan
Bought 12 pcs to build a 6s2p pack. Capacity as advertised, low IR and great discharge rate. (Posted on 24-12-22)
Great cells and service Review by Alish

Great cells Review by Vladimir
Used to build 5s pack for quad copter, flies very well. Delivers 30-40a with ease and handles short bursts up to 100a. Typical capacity is 4200, my pack have around that number.
Ordered 12 cells, they all came charged to 3.85v, all in great condition (Posted on 27-05-21)
Order 4 pieces over all very good Review by Nikolaos
Arrival was fast 10 days
beginning of April 2021

Molicell 21700 P42A
manfct: 1/March/2020 code KC01
1 year old... Thats ok

Arrival Voltage (V) 3.54 V
very good

First Charge at 0.5C end voltage 4.2 V (mah) end current <0.1C
that's fine

First Discharge 10A end voltage 2.5V (mAh)
Very good, Behaved like new.

Behavior was the same in all batteries, consistent

The only reason i gave 4 stars was that customer service could be a little less attacking.
If it wasn't for that by far the best Lion shop in Europe. (Posted on 19-04-21)
Great battery and great service Review by Martin
These are the only batteries I use these days. They edged out the 40T by a bit. Great battery and great service and communication from Nkon. Thank you! (Posted on 13-01-21)
Excellent Review by Satisfied Customer
The batteries are fantastic, but I'm sure that if you're here you already know that, so i will focus on my shipping experience instead. The package arrived ahead of time, undamaged & with minimal shipping costs (under 3e for 2 of these bulky buggers)! This was especially exciting for me, since deliveries to my nation can often times cost upwards of 20 euros even for simpler products (i.e. not batteries) from nearby countries, so i would consider this an amazing deal.
In short: Great price, great product, great service, will purchase from NKON again (Posted on 28-11-20)
best for longrange Review by Tom
Bought these for 6s pack for long range and boy I love them. 20min cruising. Delivery 1 week to Slovakia. Good quality :) (Posted on 21-11-20)
impressive cel Review by atmosphere
After discharging it to 2,5 volt and then charging it completely , my charger gave +/- 4000 mah. so that's good . But this is the type of cell you buy when you want high discharge levels. In this regard it is the best available cell I believe (Posted on 30-10-20)

Legit Review by Paulo

Not 4000mah Review by Antonio
I'm hardly getting 3400mah from this cells / very disappointed (Posted on 30-03-20)
Great for long range FPV Review by Stuclik
Great choice when 4S1P 18650 packs are too small and 4S2P 18650 are too heavy for your quad.

My 4S pack is 280g and discharging it at ~10A with occasional 20A peaks in flight allowed me to discharge 4000mAh at 2.5V cutoff (and stay airborne for 25mins).

So happy :-) (Posted on 03-02-20)
Okay Review by Z4
These are okay. Bought 12 of these, consistency could be a bit better, these ended up as 3857 - 4102mAh after I tested them. I will assemble two 6S1P battery packs from these for a drone, will see how will these perform. (Posted on 18-12-19)
Perfekt Review by Nedyalko
I use 5 of them to build a Drohne Long-range endurance pack. It works great. No worries with soldering and charging. Let’s see how will it withstand the test of time. I’m not going easy them (Posted on 22-08-19)
