A spe·ci·al·i·ty distributor of rechargeable battery packs, systems and cells.

As a premier Li-ion battery pack supplier, BKR recognizes Lithium Ion battery packs as the preferred power solution for today’s portable and stationary products used in medical, aerospace, consumer, industrial, and green energy markets.

The cell in a Li-ion battery pack provides a higher energy density per unit volume and unit weight than Ni- based batteries. In addition, their higher voltage and lighter weight contribute significantly to the downsizing, weight reduction, and simplified operation of electronic devices.

As the technology has evolved and the complexity of power applications has increased, BKR has partnered with state of the art suppliers which allow us to select the best cell type and size for each application along with all of the other mechanical and electrical parameters needed to produce a quality battery product.

We offer custom battery design for the latest lithium-ion or lithium-polymer batteries. Our goal is to offer full battery design support to help create a custom pack with optimal size, capacity, voltage, operating temperature range to meet the many varied application demands.

We invite customers to visit the manufacturing facilities in Asia where your audit will see how the facilities consistently meet the most stringent requirements put in place by our R & D team. These requirements continue to evolve with the technology and requirements from the various customers in many different industries we serve. The facilities maintain an ISO certifications, and RoHS compliance and registration.

Battery Systems

BKR designs custom Battery Management Systems that integrate into your new or existing projects. We will help you with your battery requirements and battery-life goals which will result in the right architecture, functional blocks, and related ICs. This will create an optimal battery-management system and charging scheme.

Our designs can include many functional blocks including: cut-off FETs, a fuel gauge monitor, cell voltage monitor, cell voltage balance, real-time clock (RTC), temperature monitors, and a state machine.

The grouping of the functional blocks varies widely. A simple analog front-end that offers balancing and monitoring and requires a microcontroller (MCU), to a standalone, highly integrated solution that runs autonomously.

Battery Management Functions May Include:

  • Memory
  • Fuel Gauge
  • Daisy Chain
  • Cell Balancing
  • Cell Protection
  • Charge Control
  • Real Time Clock
  • Demand Management
  • Temperature Monitoring
  • History Log Book Function
  • State Machines or Algorithms
  • State of Health Determination
  • State of Charge Determination
  • Authentication and Identification

Cells We Work With Lithium Cylindrical

  • 14500 Rechargeable Li-ion Battery Cell

    These are smaller and are similar in size to a regular AA battery. Higher energy density and lower weight than other rechargeable batteries. Ideal for building power packs (i.e., RC cars, planes, robots, etc.) with fewer cells needed than for NiMH or NiCd batteries.

  • 18650 Rechargeable Li-ion Battery

    Larger in diameter and length than a AA battery size, but can vary from one manufacturer to another. However, the battery industry is striving to standardize 18650 battery size. Typically 3.6/3.7 volts with various mAh (milliamp) ratings, and 18mm x 65mm in size.

  • 26650 Lithium Iron Phosphate (LiFePO4)

    LiFePO4 batteries a have strong safety profile with superior thermal and chemical stability. Long life, slow self-discharge rates and less weight make lithium ion batteries an appealing option. They provide an effective way to make use of space and weight.

  • CR123 Rechargeable Li-ion Battery Cell

    The CR123 has become a popular choice because of its relatively high voltage (3V) and its minimal weight. A rechargeable version of the disposable CR123A. Free of memory effects with excellent high-drain performance. Can be charged up to 1000 times. Used to power digital cameras, toys, games, flashlights and portable devices.

  • 16340 Rechargeable Li-ion Battery Cell

    These are close in size to a CR123A/RCR123A battery but a 16340 battery is normally a little larger in length than the CR123A battery. The 16340 lithium battery has diameter of 16 mm and is 34 mm long. Voltages are normally different between these batteries.

  • 26650 Rechargeable Li-ion Battery Cell

    A high performance/high capacity battery for high-drain devices. High energy and low self discharge. No memory effect. The case of heat does not break down. Can be used in series or parallel in a battery pack. Long life cycle with high voltage, generally more than 3.6, 3.7V.

Cells We Work With Lithium-ion Polymer

A lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly, lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte. High conductivity semisolid (gel) polymers form this electrolyte.

These batteries provide higher specific energy than other lithium battery types and are used in applications where weight is a critical feature, like mobile devices and radio-controlled aircraft. Also a much lower self-discharge rate over Ni-Cad batteries.

A Lithium-polymer battery can be shaped to fit in an array of devices. This allows our customers to shape the battery in essentially any way they please. More freedom in designing the true power behind your devices.


Lightweight - gelled electrolytes allow the elimination of the metal shell.
Flexible form factor. With high volume, any reasonable size can be produced.
Very low profile - batteries resembling the profile of a credit card are feasible.
Improved safety - more resistant to overcharge; less chance for electrolyte leakage.


Capital Intensive - expensive to manufacture.
Higher cost-to-energy ratio than lithium-ion.
Lower energy density and decreased cycle count compared to lithium-ion.
No standard sizes. Most cells are produced for high volume consumer markets.
