Buyer will need to supply battery charging adapter cords for the batteries that want to charge. Please see the photos for what is included in this sale. If you have any questions, please send me a PM. 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.
