18650 Battery Partners - High-Drain Lithium-Ion Cell Overview

The 18650 Battery Partners’ high-drain lithium-ion cell is designed to support devices requiring continuous high power without frequent battery changes. This cell offers a 3015mAh capacity with a continuous discharge rate (CDR) of 22.1A and has a cut-off limit of 3.2V or 80°C, whichever is reached first, at 31.5A. For electric vehicle (EV) and direct current (DC) motor applications, the cell can support pulse loads of 37.1A for 5 seconds on and 30 seconds off, within defined limits.

Built with advanced NMC chemistry and utilizing high-purity materials, each cell undergoes rigorous quality checks. Testing and certification align with UN38.3, EN62133, IEC62133 2nd Edition, and UL1642 safety standards, including required documentation for MSDS, CE, ROHS, UN38.3, and transport certifications.

These cells are designed to be charged at appropriate rates within manufacturer specifications. Testing processes assess cycle life, thermal stability, voltage consistency, and resistance to ensure safety and consistent performance.

Note: 18650 Battery Partners distributes and tests these cells but does not manufacture them directly. All products meet internal and external quality requirements for performance and safety.

Important Safety Information

Lithium-ion cells can pose serious hazards if misused, including fire, burns, injury, or property damage. Please follow all safety guidelines below:

• out of reach of children and pets.
  cells to fire, microwaves, ovens, or temperatures above 100°C (212°F).
  in pockets, bags, or on your body. Always use a protective case that prevents the cells from touching each other or metal objects.
  or carry them on your body, as objects or debris may cause short circuits.
  

do not exceed the cell’s rated wattage and amperage. Using cells beyond their rated limits can lead to overheating or explosion.

Inspect for dents, tears, punctures, corrosion, or damage to the outer wrap before each use.

and remove them promptly when fully charged.

Charge only to the specified voltage (typically 4.2V) and avoid discharging below the minimum voltage (typically 2.5V).

or batteries of different brands or capacities.

non-conductive barrier prevents cells from touching each other or device metal surfaces, except at designated contacts.

Your safety is our priority at 18650 Battery Partners.

Every cell model has been tested and certified by UN38.3, EN62133, IEC62133 2nd Edition, and UL1642 accredited laboratories and testing facilities assigned by regulatory bodies.  This includes MSDS, CE, ROHS, UN38.3, IEC, PSE, Specifications, and Air/Sea Transport certifications.  We do not cut corners. We deliver what we promise… chart-topping performance, capacity, consistency, and safety.

 To expound on safety:

 • modified cathode tag consisting of higher purity aluminum is utilized to aid in lowering internal resistance
• updated poly seal with refined bitumen is installed in every cell to ensure excess pressure is controlled

 * CAN BE CHARGED AT 4.43A. This is not a misprint. 4.43A as in FOUR POINT FOUR THREE-amp charging is possible, tested, proven, and approved within all strict safety protocols set by YongDeli New Energy.
** TESTING BEYOND TEMPERATURE. int’l cells utilize both static & dynamic testing that includes but not limited to: density loss, thermal distribution, volt drop limiters, cycle life retention, and temperature. These tests are imperative to achieve true cell performance, longevity, and overall quality.
*** NOTICE: The makers do not not manufacture batteries. These are made for and licensed achieving requirements set forth.

• DO NOT PUT IN FIRE, oven, microwave, or expose to anything over 100oC (212oF)
• DO NOT  CARRY or store OUTSIDE of its protective packaging or a PROTECTIVE CELL CASE.  The protective cell case must PREVENT CELLS FROM TOUCHING ONE ANOTHER.  UNDER NO CIRCUMSTANCE  is a protective case to be put in a pocket, bag, purse, or on your body.  A protective case can be carried by hand in a controlled manner and/or stored where it is not subjected to movement or extreme temperatures.
• DO NOT PUT IN POCKET, bag, purse, or on your body (applicable at all times and in all circumstances).  Pockets contain KEYS, COINS, OBJECTS, and/or DEBRIS that can short-circuit a cell (battery) that can result in an explosion.  The cell is to be stored in its protective packaging or a protective case that prevents cells from touching one another.  UNDER NO CIRCUMSTANCE ARE CELLS (batteries) TO BE PUT IN A POCKET, bag, purse, or on your body.  With cell(s) in a protective case, carry by hand or store where cell(s) are not subjected to movement.
• DO NOT PUT A DEVICE WITH CELL(S) INSTALLED IN IT IN YOUR POCKET or ON YOUR BODY.  As unlikely as it may be, a device can malfunction and/or be affected by debris or object(s) in the pocket that can short-circuit a cell causing it to explode.  Additionally, removable-battery devices enable the cell(s) to move/shift inside a device which can subject cell(s) to condition(s) that put wear and tear on a cell’s protective label/wrap/skin barrier.  This can lead to a short-circuit and potential explosion.  Being in a pocket subjects the device (and cell(s)) to abrupt and jarring movements.  Carrying and using the device with hand(s) is proper.  ** we encourages to use a fire-retardant case/enclosure to carry device(s) with cell(s) installed inside it (applicable to device(s) with external and/or removable cell(s)). 
• DO NOT USE IN A DEVICE THAT CAN EXCEED MAX CELL WATTAGE (W) or AMPERAGE (A) (listed on each cell and retail packaging).  Otherwise, this can overload a cell, causing it to explode.
• DO NOT USE A LOWER RESISTANCE (Ω) # (listed on each cell and retail packaging).  Otherwise, this can overload the cell(s), causing it to explode.
• DO NOT USE CELL WITH ANY DAMAGE TO ITS STRUCTURE OR OUTER PROTECTIVE LABEL (also called “WRAP”, “sleeve”, “skin”). Damage may include: dent(s), tear(s), nick(s), puncture(s), corrosion, or any other undisclosed abnormalities or damages.  Otherwise, a cell can short-circuit and explode.  ALWAYS INSPECT cell VISUALLY and by TOUCH to SEE/FEEL for damage BEFORE EACH USE.  ** SEE THE ILLUSTRATION BELOW AS A GUIDELINE. **
• DO NOT LEAVE UNATTENDED WHILE CHARGING, & IMMEDIATELY REMOVE CELL(s) FROM CHARGER ONCE FULLY CHARGED to ensure it is not exposed to any potential charger malfunction such as overcharging which could damage the cell causing it to explode.
• DO NOT CHARGE HIGHER THAN MAX CHARGE VOLTAGE (V) (typically 4.2V) or DISCHARGE BELOW MAX VOLTAGE CUT-OFF (V) (typically 2.5V).  Overcharging or over-discharging cell(s) can cause irreversible damage and cause it to explode.
• DO NOT MIX WITH USED or DIFFERENT BATTERY TYPES. Differences in cell capacity can lead to one or more cell(s) being overcharged or over-discharged. 
• IF USING A MULTI-CELL DEVICE, the device MUST HAVE A NON-CONDUCTIVE BARRIER (typically plastic) OR FITMENT that PREVENTS CELL(S) from TOUCHING THE SIDE(S) OF ONE ANOTHER OR ANY ADJACENT METAL except for the very center of top and bottom of the cell. Otherwise, cell(s) could short-circuit and explode.
• ALWAYS REPLACE CELL when capacity has decreased or within a maximum of 12 months of use (whichever occurs first) when used in a device that allows cell(s) to be changed/removed.  Cell degradation and wear incurred from repeated installation/removal can negatively impact cell integrity and subject it to conditions that can cause it to be short-circuited and explode.
• ALWAYS charge, connect, and operate cell(s) within their capabilities as listed on each cell, packaging, and all product detail pages, while adhering to the device’s user manual.
• COMPLETELY READ and follow the WARNING section listed on each cell, packaging, and here, in its entirety.
• Understand the importance of consistently taking safety precautions and using Li-ion cells properly.  Cell advocates recycling and replacing any damaged Li-ion cell/battery. As a tool to find your LOCAL RECYCLE CENTER.
