Our Technology

Built-In Battery Management System

Our Advanced Lithium Ion Technology includes a built-in Battery Management System (BMS) that protects the battery against short circuit, reverse polarity, over and under voltage, and over current. Our batteries are engineered with the highest quality components to maximize the performance of your battery system.

VOLTAGE

Lithium-ion batteries maintain their voltage throughout the entire discharge cycle. This allows for greater and longer-lasting efficiency of electrical components. Lead acid voltage drops consistently throughout the discharge cycle.

WEIGHT

Lithium-ion batteries are one-third the weight of lead acid batteries.

EFFICIENCY

Lithium-ion batteries are nearly 100% efficient in both charge and discharge, allowing for the same  amp hours both in and out. Lead acid batteries’ inefficiency leads to a loss of 15 amps while  charging and rapid discharging drops voltage quickly and reduces the batteries’ capacity.

DISCHARGE

Lithium-ion batteries are discharged 100% versus less than 80% for lead acid. Most lead acid  batteries do not recommend more than 50% depth of discharge.

CYCLE LIFE

Lithium-ion batteries cycle 5000 times or more compared to just 400-500 cycles in lead acid. Cycle  life is greatly affected by higher levels of discharge in lead acid, versus only slightly  affected in lithium-ion batteries.

COST

Despite the higher upfront cost of lithium-ion batteries, the true cost of ownership is far less than lead acid when considering life span and performance.

ENVIRONMENTAL IMPACT

Lithium-ion batteries are a much cleaner technology and are safer for the environment.

QUALITY CONTROL / SAFETY INFO

Altitude Simulation

Test batteries or cells shall be stored at a pressure of 11.6 kPa or less for at least six hours at ambienttemperature

Thermal Test

Test cells and batteries are to be stored for at least six hours at a test temperature equal to 75°C, followed by storage for at least six hours at a test temperature equal to - 40°C.. The maximum time interval between test temperature extremes is 30 minutes. This procedure is to be repeated 10 times, after which all cells and batteries are to be stored for 24 hours at ambient temperature (20°C). For large cell and batteries the duration of exposure to the test temperature extremes should be at least 12 hours.

Vibration

Cells and batteries are firmly secured to the platform of the vibration machine without distorting the cells in such a manner as to faithfully transmit the vibration. The vibration shall be a sinusoidal waveform with a logarithmic sweep between 7 Hz and 200 Hz and back to 7 Hz traversed in 15minutes. This cycle shall be repeated 12 times for a total of 3 hours for each of three mutually perpendicular mounting positions of the cell. One of the directions of vibration must be perpendicular to the terminal face. The logarithmic frequency sweep is as follows: from 7 Hz a peak acceleration of 1 g is maintained until 18 Hz is reached. The amplitude is then maintained at 0.8 mm (1.6 mm total excursion) and the frequency increased until a peak acceleration of 8 g occurs (approximately 50 Hz). A peak acceleration of 8 g is then maintained until the frequency is increased to 200 Hz.

Shocks

Test cells and batteries shall be secured to the testing machine by means of a rigid mount, which will support all mounting surfaces of each test battery. Each cell or battery shall be subjected to a half-sine shock of peak acceleration of 150 g and pulse duration of 6 milliseconds. Each cell or battery shall be subjected to three shocks in the pos tive direction followed by three shocks in the negative direction of three mutually perpendicular mounting positions of the cell or battery for a total of 18 shocks.

External Short Circuit

Test batteries or cells shall be stored at a The cell and battery to be tested shall be temperature stabilized so that its external case temperature reaches 55 2 and then the cell or battery shall be subjected to a short circuit condition with a total external resistance of less than 0.1 ohm at 55 2. This short circuit condition is continued for at least one hour after the cell or battery external case temperature has returned to 55 2. The cell or battery must be observed for a further six hours for the test to be conclude. Cells and batteries meet this requirement if their temperature does not exceed 170 and there is no disassembly, no rupture and no fire within six hours of this test.pressure of 11.6 kPa or less for at least six hours at ambienttemperature

Impact

The test sample cell or component cell is to be placed on a flat surface. A 15.8 mm diameter bar is to be placed across the center of the sample. A 9.1 kg mass is to be dropped from a height of 61 2.5 cm onto the sample. A cylindrical or prismatic cell is to be impacted with its longitudinal axis parallel to the flat surface and perpendicular to the longitudinal axis of the 15.8 mm diameter curved surface lying across the center of the test sample. A prismatic cell is also to be rotated 90 degrees around its longitudinal axis so that both the wide and narrow side will be subjected to the impact. Each sample is to be subjected to only a single impact; Separate samples are to be used for each impact. Cells and component cells meet this requirement if their external temperature does not exceed 170 and there is no disassembly and no fire within six hours of this test.

Forced Discharge

Each cell shall be forced discharged at ambient temperature by connecting it's in series with a 12 V D.C. power supply at an initial current equal to the maximum discharge current specified by the manufacturer. The specified discharge current is to be obtained by connecting a resistive load of the appropriate size and rating in series wit
