Lithium-pack compatible! Capable of charging and discharging 1-3 cell Lithium-Ion or Lithium-Polymer packs — or peaking, discharging and cycling 1-10 cell NiCd or NiMH packs. Includes the Auto Smart Set feature for amazingly fast, easy and accurate results. Enter battery type, capacity and voltage, and the Auto Smart Set automatically calculates safety time-out, charge rate, trickle rate and discharge voltage cut-off. Prevents overcharging with peak detection for NiCd and NiMH packs and cc/cv detection for Li-based packs, plus safety time-out and optional temperature sensor (HCAP0281) features that work with all three types! Easy-to-follow flow charts are included that show how to manually program charge/discharge/cycle routines for individual packs. Stores routines for up to 10 packs in memory and a wealth of data about each. Easier to read and understand. On-screen messages feature fewer abbreviations, better explanations and units of measurement with every number — and appear on a big 2-line/16-character LCD! Offers the ability to handle one pack at a time, or two packs simultaneously — even if the packs are of different cell chemistries. AC/DC compatible — ideal for at-home preparation or at-field recharging
