I needed a charger to do the longer 21700 cells and I went with the Miboxer C4-Upgrade. One amp for all 4 bays, or 1.5A for two bays is adequate for me. I’ve been happy with it. I like that it has the option for 12v with a standard 5.5 x 2.5mm jack or can plug in an AC cord. The Miboxer Upgrade C4-12 only has 12v input which is fine by me too. I use a 12v power supply that can source more current than most wall transformers. Nice to be able to use in the car.
For discharge capacity testing, I have a dedicated capacity tester (a ZHIYU) and didn’t need it built into the charger. (but seldom find a need to use it anyway). The new Miboxer Upgrade C4-12 (now has two yellow buttons) wasn’t available when I got my C4-Upgrade. Still waiting for it to become available on Amazon.
All my chargers have slightly different termination voltages. I prefer the ones that terminate a little under 4.20v, but some terminate higher. It won’t damage the cells, but you’ll get maybe 10% less cycles from them. You’ll also get a bit more capacity out of them, though probably only 1% - 2%.
My Xtar X4 terminates around 4.18v. So, I don’t think Xtar is designing chargers to terminate high. It’s just the random variance in the chips that all companies use.
I think my next charger will be the SkyRC MC3000, because you can set the termination voltage to whatever you want.
Sounds nice, but I don’t know if that would be very “budget” friendly.
What about XTAR or Opus for the BLF edition? Can we get the Vape folks on board? BLF/ECF Edition?
That is why I said “SkyRC like” … big, robust, charge at least 3A x 4 bays, discharge at least 2A x 4 bays, active cooling that works, manual settings, easy & straight forward to use.
I would just as soon have no bells & whistles… but that’s just me.
