A hobby charger might be a better option if you feel comfortable using one. There’s a bit of a learning curve but nothing to difficult.
It will charge just about anything you throw at it with lots of options.
I’ve got the BT-3400 v. 2.2 and I’m quite happy with it. You can remove the bottom half of the case and drill a hole over the slider switch, so you can do LiFePO4 chemistries, using a toothpick, or small non-conductive screwdriver.
For 9v, I use the Tenergy 2 bay smart charger and 4 Centuras and they’ve worked out well for ~5 years.
I know a lot of folks are standing by their Opus products, and I was sorely tempted as I know that would have been a safe and quality choice, but I went with the AccuPower IQ338 (though not the XL version). Mostly this was arbitrary on my part: but the AccuPower just looks (slightly) easier to use, nobody else spoke about it (I am all for the path less traveled) and it was a bit less than the Opus BT-C3400 (Amazon pricing). Maybe I’ll eat my words and wish I bought an Opus. We shall see!
The hidden switch on the Opus does indeed work. You can do high voltage Li-on, and LiFe batteries, which also happens to work out well for Li-on ~ storage level. :THUMBS-UP:
Cut a hole so it’s easy to get at.
The charger gets a lot of complaints in the forum but I think it’s one of the best buys available….if you replace the power supply and add some extra cooling. FWIW the cooling is what allows it to charge at higher amps and more cells than a lot of competing units.
Considering that it was a $90 charger when it hit the streets, $65 shipped is a good deal. The SkyRC MC3000 is still $90-$100+ shipped, so there’s a fair difference in price between the two.
Personally, I think that the Opus BT-3100/3400 v. 2.2/3.1 are pretty good deals at ~$40 (I paid $51) especially if you’re not a knob twiddler and don’t really need the Nth degree of ‘geekness’, which I don’t.
Still, I never felt I needed an Opus and I ended up getting one and I swore I’d never get into li-ion cells and lights, after revamping my NiMH stash in 2012, but here I am, 25 chargers later.
I like Xtar and HKJ reviews it favorably, but no charger is perfect. For most of my needs, the Opus 3400 is more than sufficient.
Not really a tweaker. The SkyRC looks great but looking into it I’m seeing complaints of slider pegs breaking, buggy firmware, and loose, floppy buttons. Some people are asking for the hardware versions of the SkyRC before buying for some reason.
