About the Cellpro 4s Discharge Protection Module
The Cellpro 4s Discharge Protection Module (DPM) prevents FMACellpro Battery Packs from overdis-
charging in electric-powered radio controlled aircraft. Cellpro Packs have special connectors that enable
Cellpro 4s Discharge Protection Modules (as well as Cellpro 4s Charge Protection Modules) to monitor
the voltage of individual cells within the pack.
About the Cellpro system. Your airborne power supply will be made from two kinds of components:
CellproPack(s). Each pack has a special connector that enables Cellpro components to monitor the
voltage of individual cells within the pack.
Cellpro 4s Discharge Protection Module (DPM) for each Cellpro Pack. During discharge
(ying), the Cellpro 4s DPM monitors individual cells within the connected pack and pro-
vides a warning when voltage gets low. A complex algorithm determines when the rst cell
reaches a preset voltage. At this time, the Cellpro 4s DPM works with your existing ESC to
cut voltage to the motor.
For charging you’ll need one of the following:
Cellpro 4s Charger.
or
BalancePro HD Charger with BalancePro HD-to-CellproAdapter, which automatically bal-
ances each cell and prevents overcharging. Besides providing fast charging, this combination
enables Cellpro Packs to deliver longer life, as well as longer and consistent ight duration.
or
Other LiPo charger and Cellpro 4s Charge Protection Module. This setup prevents over-
charging, but cannot perform cell balancing. Over time, the pack may become unbalanced,
reducing ight duration.
Cellpro 4s DPM features
Works with any Electronic Speed Control (ESC).
Enables use of LiPo batteries with both brushed and brushless ESCs.
Soft cutoff gives you time to set up for landing before battery is depleted.
Handles up to a 4s Cellpro Pack.
Three Cellpro 4 DPMs can be daisy-chained to handle up to 12 cells in series.
Connects to ESC through Deans Ultra connectors.
CP4S-DPM-OPTO only: Optical isolation prevents interference from propagating back to receiver.
Optional LED/Speaker Module provides status information.
Precautions
Read and follow all precautions provided with LiPo packs and chargers.
