TrakPower VR-1 Dual Racing Charger - Manual (Page 2)

2
The TrakPower VR-1 Charger is a fully programmable, high performance, computerized battery
charger designed with the electric racer in mind. Dual outputs with built-in balancing provide
the ability to charge two batteries simultaneously and eliminate the need for a separate in-line
balancer. Capable of charging all chemistry types in the R/C industry, the VR-1 is a top of the line,
state-of-the-art battery charger. A large, tilt-able, reversed backlit graphic LCD makes it easy to
view at any angle, indoors or out. Able to charge at 20A on channel 1 (up to 6S) and 6A (up to 4S)
on channel 2, the TrakPower charger quickly and safely charges batteries so you can get back
on the track!
STOP!! It is strongly recommended to completely read this manual 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-
based 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
