Awesome battery charger for all types of batteries

The S6 is an awesome little charge. For my use cases the iCharge S6 is well worth the cost difference between iCharger S6 and the somewhat comparable ISDT Q8. Ive found the iCharger S6 easier to calibrate, The customization of charge and discharge profiles is awesome.

I have custom jigs for testing different battery types, so having the ability to load different configuration/ Calibration profiles for each jig or leads is outrageously indispensable. This allowed me to load the calibration done at the battery contact points but also load only the viable charge and discharge profiles for the battery(s) that can be tested in that jig and omit all profiles/ configuration that should not be used on a particular jig/ battery.

Ive tested the iCharge S6 on 3S Lipo’s, 1S~5S Li-Ion’s, 3S2P Li-Ion’s, 12V35Ah, 12V14Ah, 12V9Ah, and 12V4Ah AGM’s. The S6 did well on all of them.

UPDATE: After about 60 hours of charging and 13 hours of data logging the S6 turned off in the middle of a charge and unit wont turn back on.

I got a second S6 and has been working flawlessly. I highly recommend the S6 despite the misfortune I had with the first unit.

Great charger and quality

Software is easy to use. Only needs a better way to name a new profile.
