The Onyx 150 a great choice for any modeler who wants an easy, economical answer to balanced 1-3S LiPo charging. A tiny built-in power supply makes it easy to take along and use anywhere there's AC power. Once it's plugged in, just set the switch to 1.5A, 3.0A or 5A, listen for the confirming sound cue — and let the Onyx 150 do the rest. It starts automatically when the pack is hooked up and includes a tri-colored LED that constantly shows charge status. Balancing and cc/cv charging ensure that each cell reaches its maximum voltage.
