Voltage reading is a bit off, but charges correctly.
I bought the E4 for Lithium Ion cells primarily. It charges them just fine and works! The Bluetooth is a bit gimmicky due to the range, but it always charges my cells between 4.20v and 4.22v. One small gripe I have is that it seems to read the battery's voltage wrong, but still charges correctly. If I put a cell that's about 3.70v for instance, it will read it correctly at first, and then climb up to 3.84v or 3.90v and THEN start charging. Weird really, but has never over charged a cell, not once!

Good charger quality
Good charger quality. Setting battery type must be redone for each cell each time you charge. Does not remember last setting. Charger will not hold four 26250 cells from A123 LiFePO4. I can charge only three at a time.

i bought this product but when you read the specification ...
i bought this product but when you read the specification said for batteries NI-MH current only .025 Amps. You can't modify this.This is not what i looking for. very disapointed

do not buy
the build quality feels great but most of the features of this charger is locked behind an app that is no longer available it can charge batteries but any of the smart features are charging regulation need the app to work

ESYB charger
Works well has alot of information about battery being charged also like the bluetooth the info shows up on my phone so I dont have to keep getting up to look as its charging lol the only thing I had a problem with is finding the APP FOR BLUETOOTH FUNCTION is on the website itself not in the play store so you need to hunt around for it that is the only reason for 4 stars other than that its great

Well worth the money. This unit can charge two completely dead 35amp high drain 18650 batteries in 2 amp mode in roughly 30 to 45 minutes.
