AC/DC 1–14 Cell Variable Rate
Peak Prediction Charger
Instructions
Thank you for purchasing the E-flite™ P™ AC/DC Peak Prediction Charger. The P can be powered from
either a 110V AC or 12V DC power source, and will peak charge and discharge 1–14 cell (1.2–16.8V) Ni-Cd and Ni-MH
battery packs. It features a 16-bit microchip CPU controller with a large LCD display indicating capacity, voltage and
charge rate.
The P has unique peak prediction circuitry that ensures your batteries receive an accurate charge every time,
and protects your Ni-Cd and Ni-MH batteries from the dangers of overcharging. The P does this by continuously
monitoring the battery’s voltage curve and calculates (predicts) when the peak (100% charge) will occur.
When the batteries have peaked, the P stops fast charging at exactly that point and then advances to trickle
mode. This is essential in order to avoid damaging Ni-Cd and especially Ni-MH cells that are sensitive to overcharging.
This circuitry is superior to conventional peak detection circuitry, which continues to fast charge even after the batteries
are fully charged, and can cause damage to Ni-Cd and Ni-MH cells.
