Questions about imax b6 operation


I have a genuine skyrc imax b6 charger. It comes with a 12v (5a, I think) power brick, connectors, and the wifi dongle.

First question: Can I charge 1s HV packs to 4.35v? If so, how?
It seems I can only set the charge voltage to 4.30v. Do I simply need a bigger power supply? Or is that a hard-stop in the imax itself?

2nd question: should I be able to set the imax to 4.2v and expect a single battery or a set of 4 batteries in parallel to end up being charged to 4.2v?
I made my own parallel harness, and also now have a crazepony parallel board. (No need to discuss the pros/cons of parallel vs serial; let's just pretend that parallel is the way I want to go for now. :-) ) So far I charge 4x 1s gumstick whoop batteries at a time.

But in the above scenario, the batteries always end up only charged to between 4.0v and 4.12v (whether I'm charging 1 or 4). If I crank up the voltage on the charger to 4.25v, then I can get the batteries up to 4.2v, but it takes much, much longer to get that extra .08 to .2v. Am I doing something wrong?

3rd question: Will somebody who uses this particular charger regularly to parallel charge 1s gumstick batteries to 4.2v please upload some screenshots of the settings you use? Also, if you're using this charger to charge 1s HV batteries to 4.35v, please upload some screenshots of how you're doing it.

Thanks!

If you have the B6AC V2 you can do LiHV cells.

a LiHv can not be charge to full voltage with this charger it does not support LiHv.... a 1c charge should be complete on a lihv charger in a hour..

since this has a power brick a external power supply it is not a imax b6ac v2

My B6 only knows 4.20V for Lipo charging.

Thanks for the responses so far guys! Yeah, I don't have the b6 v2, so no HV. However, I do have the wifi dongle and in the app I can go up to 4.3v...and my batteries end up at 4.26v.

So, any takers on my 2nd question: should I be able to set the imax to 4.2v and expect a single battery or a set of 4 batteries in parallel to end up being charged to 4.2v?

My batteries never end up at the voltage that I set the charger to. Any idea why?
