Lightning is a professional NiCd / NiMH battery discharge and equalizing system developed by TEAMWAVE.

After years of research and development, TEAMWAVE successfully
developed Isolated Cell Discharge & Monitoring circuitry (I.C.D.M.)
and Adaptive Current Control System (A.C.C.S). With the introduction of
these state-of-the-art technology, serious racers can now enjoy precise
voltage cut off, individual cell voltage monitoring and varying
discharge current in one compact unit.

Each battery is discharged and monitored through
a pair of high power transistors in the Lightning system. The circuitry
for each cell is optically isolated from each other to ensure accuracy
and independency. Built-in over-sized heat sink and high power fan help
dissipate heat efficiently. Individual cell voltage and discharge
status are clearly displayed through the blue backlight / white
character LCD.

Another key feature is the Adaptive Current
Control System (A.C.C.S). Onboard computer will automatically adjust
individual cell discharge current according to its voltage. It’s just
like having one independent discharger working exclusively for each
cell in the pack! You can have all cells in a pack discharging at
different currents at the same time! Once the battery pack (1 - 6cells)
is put on the tray, the system will start with the maximum possible
discharge current (~5A depending on battery condition). When cut-off
voltage (User select from 0.7V to 1.0V in 0.01V increment) is reached,
the system will automatically lower the discharge current so as to
maintain the cell voltage at the desired cut-off level and let the
discharge process to continue. Compared with traditional discharge
tray, the discharge process is considered finished and the pack will be
cut off at this point. In fact, plenty of charges are still stored in
each cell. A pack cannot be effectively equalized if there are still a
lot of charges inside each cell. Currently you may resort to a pure
resistor tray to get rid of the remaining charges and thus equalize the
pack. However, these discharge trays do not have any cut off mechanism
and may cause permanent damage to the cells. This is especially
undesirable for the new generation high capacity cells which do not
like over-discharge below a certain voltage threshold. (For example,
IB3800)

Isolated Cell Discharge & Monitoring
circuitry (I.C.D.M) allows the system to discharge and monitor each
cell individually. Relative energy (charges) left in the battery is
also displayed. The bottom left image indicates that two of the cells
have finished discharging while the remaining cells are still
discharging.By adopting I.C.D.M.
technology, “Voltmeter” function is included in the Lightning system
such that user can check individual cell voltage. In voltmeter mode,
users can also connect their charger to the system such that individual
cell voltage is monitor and displayed during charge.
