18v lithium ion battery pack Production
The 18v lithium ion battery cells are chosen in great consistency of voltage, internal resistance, and capacity to ensure the excellent performance of the battery pack.
Besides the normal quality tests, all the battery packs are subjected to rigorous tests of aging, overcharging& overdischarging, capacity, vibration, and communication verification.
All the test data are kept in our system for three years for quality traceability.
Custom 18v Lithium Ion Battery Manufacturer In China
Configured with 5pcs lithium ion battery cells in a series, the 18V lithium ion Battery has an 18V nominal voltage and a 21V fully charged voltage. Lithium-ion 18V battery is widely used in branded power tools, such as for Dewalt, Makita, Milwaukee, Ryobi, and Bosch. The 18V lithium ion battery cells should be high-drain cells, capable of delivering 10C-20C burst current and generating less heat.
Different from the normal power tool batteries, VTCBATT can custom-design 18V lithium ion battery pack to suit different applications in electric equipment, lighting, and portable devices.
The size and performance can be specifically designed for the customer’s design. No matter whether you want a waterproof case, specific ports for charging and discharging, or high capacity to support long runtime, VTCBATT can make it exactly. Furthermore, we can help you source the matched 18v lithium ion battery charger as a kit together to bring you great convenience.
Lithium Ion 18v Battery Models




Advantages

Most 18V lithium-ion battery uses a very high-drain cell to ensure a strong power supply for power tools and equipment in any conditions. High-drain cells of 18650 and 21700 models can deliver a max 30C rate to fully meet your burst power demand and power your devices strongly.

The lithium ion 18v battery is not only provided with smart BMS protection against over-charge,over-discharge,over-current, and short-circuit, but also integrated with fuse, NTC, and PTC to sense the temperature and current to ensure safe operations at any time.

Due to multiple cell configurations, the 18V lithium ion battery cells are placed in the cell holder, which can not only separate the cells for insulation, but also ensure a solid structure of the total 18v lithium ion battery pack during transportation and movement.
Key Features of VTCBATT lithium ion battery

18v lithium ion battery can be fully customized into different sizes to fit the limited space perfectly and maximize the energy output. Any specific communication protocol or charge&discharge output port can be tailor-made for your product under strict confidentiality to protect your business.

18V lithium-ion battery is assembled with a customized connector to plug easily and be durable in frequent usage. Furthermore, VTCBATT can also recommend the most suitable and safe connector to satisfy your product, removing any risk of danger or failure.
Application for 18v lithium ion battery
Power Tools18v lithium ion battery packs are widely used in all the branded power tool brands, such as DeWalt, Makita, Bosch, Milwaukee, and Ryobi. Besides power tools, it can also provide a reliable and strong power supply for the electric drill, vacuum cleaner, impact driver, and hammer drill.
Portable EquipmentFeaturing high energy density, lithium ion battery 18V is lightweight, low self-discharge rate, long runtime, and fast rechargeability as the power source for portable equipment.
Led light& Emergency lightIndustrial LED lights are normally designed in the 18V platform, which allows the direct connection of an 18V lithium-ion battery pack to illuminate the led light brightly.
Audio SystemMost audio system supports 10-24V DC input, using lithium-ion battery packs in 18V and 12V.
The stable power supply can ensure high-quality voices and an extraordinary experience.
A: Besides a specific charger, you can use the power supply to charge the 18V lithium-ion battery. Set the power supply voltage at 21V max and regulate 0.3C-0.5C current limits.Till the battery pack voltage reaches 21V, stop charging.
But power supply doesn’t have CV charging phase,which can’t fully charge the battery.
It can only be used as an emergency source to charge the battery.
A: 18V lithium ion battery consists of 5 cells lithium ion cells in 18650 model or 21700 model. It has 18V nominal voltage and 21V fully charged voltage.
A:Lithium ion battery repair carries risks of short-circuit, vent, ignite, or explode under improper operation. There are common problems for fixing 18V lithium ion batteries.
(1}Not charge
When the 18V lithium ion battery pack voltage dropped below 14V,the 18V BMS protection is locked and can’t charge.You just need to charge the 18V batteries to activate the charger.
Most 18V lithium ion batteries are for power tool applications and are provided with metal contact.When the metal contact is damaged,dirty or rusty,it may cause the battery can’t charge.
(2) Deeply discharge
When the battery is in a deep discharge state, the battery can’t be activated by the charger.
You must use the charger with a pre-charge function or zero charge function; even when the battery is 0V,the charger can identify the battery and charge it.
(3)Shorter runtime
The shorter runtime may be caused by cell imbalance, high internal resistance, poor charging, and long-time lay aside, etc. For cell imbalance, you need to use a specific charger with a cell balance function. High internal resistance may be caused by battery aging. Poor charging may result from a short charging time. After a long time lying aside, the battery capacity will degrade, and it is better to do more cycles of full charge and discharge to recover.
(4) Battery Overheat
Don’t use the battery in high-temperature or high-load tools, which will cause the battery overheat.Stop using the battery! Cool the battery immediately!
A: Due to the rapid development of EVs, each year thousands of EV lithium ion batteries are retired and replaced by new batteries, which are called second-life batteries. Although those battery packs are not so durable in EVs, they can be used in many applications. Professional recycling companies will disassemble them into modules and test their health and capacity.
Then assemble the modules into to home energy system, solar energy storage, and low-speed vehicles.
A: 18V lithium ion batteries are widely used in power tools, electric drillers, vacuum cleaner, electric mown,ect. You can re-use the power tool batteries as emergency home backup power.But you can use a specific battery adapter with USB to charge phones,powering routers and camping gear and lighting some bulbs.
