Using 1.6A/0.33C charge current with 242.5mA/0.05C cut-off and 4.85A/1C discharge with 2.5V cut-off after 1000 cycles the capacity should be ≥3880mAh (80% of std capacity).ĭC IR at 4.85A in fully charged condition was 20☑mΩ (measured using EB Tester Software's Resistance test feature). Samsung 50G has the following specs according to its official datasheet ( pdf):

There is also a 2D matrix code and 2 other markings: Samsung INR21700-50E 5000mAh (Cyan) Official specifications: Standard discharge capacity: 4900mAh (0.2C discharge) Rated discharge capacity: 4753mAh (1C discharge) Charge voltage: 4.2V Nominal voltage: 3. The printing is not resistant to ethanol-based degreasers and is washed away easily, so if you're going to put a tube on 50G be careful while degreasing the cell surface. Samsung 50G comes without any heat shrink tube on it and all the markings are printed on the cell barrel. ago Nope, just based on the max power of the device. ago Yep, all of those are great for 21700 mods. To be sure in results i've done each test minimum twice ( usually 3-7 times). Battery 21700 is the type of cylindrical battery, specifically: 21 - refers to the outer diameter of the cylindrical battery is 21mm 700 - refers to the height of the cylindrical battery is. 30T, 40T, p42a are the ones to use for 21700 devices St1llFrank 2 yr. Before each discharging or charging i've held a 1-1.5hr pause. 21700 battery is short-hand for a rechargeable, lithium ion battery that is 21 mm in diameter and 70 mm long. Before each discharging cycle the battery was charged at standard charge current mentioned in its datasheet to charge end voltage. I think Vapcell said they will be trying to source both of these, but I doubt they will be able to anytime soon so if anyone is in the market to buy high capacity 21700 cells, don’t wait on it.I've followed all the prescriptions of the IEC61960-2003 standard concerning battery's capacity measurement. Capacity: 4007mAh Max Charge Rate: 6.01A Max Charge Voltage: 4.2V Continuous Discharge Rate: 30.3A Max 80oC 3.2V cut-off: 38.6A Pulse Peak: 44.1A. Your coil resistance doesnt matter when determining battery current, just the wattage setting. Pulse-Current Test Results Comparisons against Sanyo 20700 cells. 2) The battery casing, as the 21700 battery has a larger diameter and can hold more cells, therefore the casing required per Wh is 33 less for the 21700 battery than for the 18650 battery. I am rating this iJoy cell at 24A and 3650mAh. Ouch! Therefore I think the best high capacity on the market right now is the Lishen LR2170SF until the Molicel M50 or Lishen LR2170SC becomes available. This cell is not a rewrap of any other 21700 that I am aware of.
The button top version soldered on by Vapcell adds so much resistance that it performs significantly worst than even the 48G. I bought both the Vapcell recessed top version and button top version. I don’t like the Panasonic (Sanyo) NCR21700 5000mah battery because of the recessed top, it will not work in my charger. Published + Follow Tesla Elon Musk: 18650 battery is an accident, the future is 21700 At the end of July, Tesla released its fourth model Model 3, the mileage of 354 km and 499 km. Featuring a 4200mAh capacity and a discharge rate.

Not sure what NMC and NCA mean, but if the Lishen LR2170SF 4550mah (I measured at 4,7xx - 4,8xx mah) measures at a mere 150 - 200mah less than the Samsung 50E and LG M50 (I measured both at 4,9xx mah) but is actually in a higher performance class of the likes of 40T and P42A, then that makes the Lishen even more amazing! I replaced my 48G, 50E and M50 with the Lishens in my mid power 21700 lights because I know it will maintain a higher output level throughout the entire discharge curve and the price is good. The VAP Procell 21700 Battery is a option for a huge range of vape kits and mods that support 21700 batteries. Lishen SF is capable of 20A, while Samy - LG for 10A. Please Note: The Pulse Discharge Rate refers to the maximum output of a fully charged battery, the Continuous Discharge Rate refers to the maximum power output. Graphical comparison to 18650 and other batteriesīut here we are talking about a different type of battery …

How is the test done and how to read the charts This thing really runs like a beast now its crazy its completely worth it imo for the extra battery life and power. The batteries was supplied by for review. This is a good quality battery and with high capacity. The two cells are very well matches, but they do not like high current (I forget thermosensor on one of them, it survived, but must have been hot). This is one of the new high capacity 21700 cells. Operating temperature: Charge: 0☌ ~ 45☌, discharge: –20☌ ~ 60☌ Maximum continuous discharge current: 9800mA Rated discharge capacity: 4753mAh (1C discharge) Standard discharge capacity: 4900mAh (0.2C discharge)
