A CamLight Systems 2-Stage Pack Discharger uses durable power-resistors and an auto-cutoff switch to discharge your NiCd or NiMH battery packs. It accurately monitors your pack's voltage level as it discharges and disconnects the load when the battery pack has reached the selected cutoff voltage.

These Pack Dischargers use two stages:
• Stage-1 - An adjustable higher-current discharge to quickly bring the pack down to 0.8V-1.1V/cell (adjustable for the PD-12V, fixed at 0.9V/cell for the MiniPD-12V).
• Stage-2 - A lower-current discharge to again bring the pack down to 0.8V-1.1V/cell (adjustable for the PD-12V, fixed at 0.9V/cell for the MiniPD-12V) to ensure a complete discharge.
This 2-Stage discharge occurs automatically and helps to properly condition your packs better than high-current single-stage dischargers. And its much faster than any low-current single-stage discharger!

Pack Dischargers can be used to:
• Safely condition your NiCd battery packs by making it easy to discharge to a known voltage every time.
• Measure the capacity of your NiCd/NiMH battery packs by using the Pack Discharger along with a watt-hour meter.
• Quickly discharge your battery packs down to 0.8V-1.1V/cell before placing them in a discharge tray (to discharge each cell individually).
Our Pack Discharger's small size and low weight allows you to take it wherever you need to discharge your battery packs. No need for AC power or another battery to worry about, our Pack Dischargers run themselves from the battery pack being discharged.

Also with the following features:
• Accurately monitors a NiCd/NiMH battery pack as it discharges down to a selected cutoff voltage.
• Automatic 2-Stage circuitry quickly discharges your packs. No more having to settle for only one discharge current level or hours of waiting for a low-current discharge to finish.
• Adjustable discharge current to better match the capacities of your different battery packs.
• Solid-state output, no relay contacts to arc or stick together.
• Green LEDs indicate the pack is discharging and which Stage is active. Red LEDs light up when you connect the battery pack with the leads reversed.
• Durable silicone-insulated wire leads, wire-tied in place.
Our larger dischargers also have the following features:
• Adjustable per-cell cutoffs - lets you compensate for the internal resistance of the pack and its influence on the pack's voltage at higher discharge current levels. This will ensure a more complete discharge.
• Load Module connector - lets you connect a CamLight Systems Load Module (coming soon) to increase the Stage-1 current level.

5/8/2009 WT	It does the job well... So far I've used it on 12V lead-acid and 3-cell LiPo batteries, it works just like expected. Put a "watt's up" or similiar meter in series for maH measurement.
