i needed to hear from actual people.
I'm an actual people, and have an MC3000
Regarding programming, as
@Mordacai said... the charger has a dummy mode that is ready to go for most batteries types and will just charge or discharge according to presets which works very well. If you want to have custom settings it also has normal and advanced modes that can really customize your charging, discharging, cycling, break-in, and storage modes. It's very flexible if you want that. If you don't like setting things up with the 8 on-board buttons just plug it into a PC by USB and use the free program. You can also program and monitor operation by Bluetooth with your phone or tablet.
If your goal is to only charge to 4.0v termination, you can either do that each time you charge, on a per bay basis (easy with just a couple of button clicks on the charger), or program it one time to one of 30 preset memory spots available and your done. This is not hard to do, just press one button (long press) and you can scroll through all the charge details by scrolling up or down and when you see the termination voltage just change it from 4.2 to 4.0. If you want to save that change forever in that memory location just hold the enter button for 2 seconds (and you can program 29 more programs this way if you want other custom programs). Now it's done and it will always use that termination voltage.
No matter what charger you get, if you want a termination voltage of 4.0v you will have to program it yourself. I can't think of any charger that comes at anything other than 4.2v. Even chargers that can do Hv 4.35v usually come preset to 4.2v for safety. So don't let programming scare you off since that will be the case for any charger you buy. The only thing that makes it difficult is all the available parameters you can change and tweek. But you won't need to so don't get distracted by the geeky things that can be done if you wanted to, but never will.
This is a very accurate and safe charger from my experience and after 6 months use I'm quite satisfied. If you have any other questions let me know.
