E-flite DC 1-14C User Manual

AC/ DC 1–14 Cell Variable Rate

Peak Prediction Charger

Instructions

Thank you for purchasing the E-flite™ Pinnacle+™ AC/DC Peak Prediction Charger. The Pinnacle+ 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 Pinnacle+ 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 Pinnacle+ 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 Pinnacle+ 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.

Error Modes

The Pinnacle+ features a self-diagnostic mode with the following error codes:

• “ERR1” A short circuit or the safety fuse is burned out

• “ERR2” An error has occurred in the charging process (loose connection, contacts or current is adjusted after
the initial 30-second start up mode)

• “ERR6” The peak charge is abnormal because the voltage is too low

• “ERR” The power supply is insufficient (below 10V)

Note: “ERR6” and “ERR” will only occur when using a 12V power source. To cancel error modes, disconnect the

batteries from the charger.

Supplying DC Power to the Pinnacle+

The Pinnacle+ is powered by connecting it to a 12V DC power source, such as a 12V sealed battery (HAN102),
a 12V automobile battery (car must be not be running) or through your field box power panel. The battery capacity
must be over 5Ah.

The Pinnacle+ can also be powered from a standard 110V AC outlet.

12V DC connections:

Step 1. Attach the red (positive) banana plug to the red (positive) terminal on your 12V battery or power panel.
Step 2. Attach the black (negative) banana plug to the black (negative) terminal. Alligator clips have been included to

power your charger with a 12V hobby battery. Once your charger is given power, it will beep once and the LCD
will show 28V when voltmeter is selected, which is normal.
