Today's best value in a balancing and peak charging!

You can spend more money on other chargers, but you can't find a better value in peak and balanced charging than the Onyx 225. It arrives with 10 charging routines already in memory for ease, but also gives you the power to customize any one to your specific charging needs. A 2-line, 16-character LCD with a reversed, backlit screen makes it easy to check the status of every battery operation, from initial setup to full, final charging.


Typical Application:

The charging and balancing ranges of the Onyx 225 make it a natural choice for most car, truck, boat and aircraft applications. Its 6A charging and 60W AC power supply give you the ability to handle 1-15 NiCd/NiMH cells and 1-6 lithium cells with ease. 10-model memory puts customizing power and convenience at your fingertips whenever you need them. And since the Onyx 225 offers both peak charging and balanced cc/cv charging, you can be assured of a full, deep charge for NiCds and NiMHs, as well as LiPo, LiFeSource (Lithium Iron Phosphate) and other lithium-based packs.
