This was my first peak charger well, at least in the last decade, had an old Tekin before that. It is really easy to use (it can't get much easier). Set the current, mAh, and delta peak value, and you are done. Plus, it has 10 memory slots so you don't have to re-enter everything each time you charge. Great charger if you don't need to do li-po packs or discharging.

Now, I use it in conjunction with my MRC Super Brain 977 (aka. pimp-diggity-superfly-mac-daddy-of-batteries), and I can charge my radio batteries, receiver batteries, and 12 volt starter box battery all at once (since the Super Brain 977 can do two different packs/battery types at once).

Worst case, if every battery is totally dead, between the two chargers I am never more than a couple hours away (usually more like 30 minutes just to top them all off) from having everything charged.

As for cycling, look up the moderator Red Sholefield [sic], he knows alot about this subject.
