 Onyx

 230 charger is great for a wide 

variety of applications! With charge currents up to 7 amps 
and wide output voltage range makes it equally useful for 
1/32 scale micros as for large 1/8 scale electrics, plus nitro 
receiver packs and transmitter packs. The ability to also 
handle LiPo and LiFe cells is great for upgrading to the 
latest in battery technologies. AC/DC fl exibility, plus the 
advanced reversed LCD with backlight, and simple menus 
and controls make it super-easy to use anytime. A quick 
reference fl owchart is included for easy understanding of 
all menus.
