The Onyx 245 charger is two chargers in one! Identical twin outputs make the 245 an excellent choice for models that use
two battery packs or modelers who rotate through multiple batteries at home or at the track. A built-in balancer for each port
optimizes charging of lithium packs, including LiPo and LiFe cells such as LiFeSource
with NiCd and NiMH batteries. AC/DC fl exibility, plus the advanced LCD with backlight, simple menus and controls make
it super-easy for anyone to use anytime, anywhere. Its tremendous fl exibility, small size and weight, yet high power give
racers another advantage on race day!
It is strongly recommended to read this manual completely before use! Damage resulting
from misuse or modifi cation will void your warranty.
WARNING!! Charging lithium-based rechargeable batteries poses a risk of FIRE! NEVER
treat lithium-based batteries in the same manner as other battery types. NEVER leave
lithium batteries unattended while being charged! ALWAYS charge lithium-based batteries
in a fi reproof location! Failure to follow all care and handling instructions contained in this
manual could result in quick, severe, permanent damage to the batteries and all surroundings!!
Follow all safety precautions when using such batteries, as listed on page 3 of this manual!
