Imax B6 LiPro Balance Charger Discharge Settings And How To Set A Custom Discharge Level

I've wanted to test the capacity down to 2.5v on my Li-Ion 18650 cells, in order to find out if they are close to their 3000 mAh rating, but I couldn't go below 3.0v in the standard settings on my B6 charger. Thanks to you Richard, I now have several options w/o having to go out and buy a separate load tester! This same method also works on several of my other charges, so again, great work!

Isn’t there a device similar to this where you can select the cutoff voltage of the discharge? I liked this battery analyzer but unfortunately you have limited options for discharging.

Q. How can I find out what kind of cells I have foe a down tube ebike battery and how to discharge. I just found out about this tool and is this the right one to get.
Thanks

I have a potentially newer version of the B6 (AC/DC Dual Power Professional V2), I'm not sure, but it will not let me reduce the discharge cutoff voltage to 2.6 like yours does on the screen. When I go into Skyrc I can create a custom program to discharge or charge.. etc.. I created one for these for that batter you did alot of testing on, the LIPO 200 AMP 8-9ah? With a cutoff voltages of 2.5 it refuses to start saying there is an issue with the main port. If I do a normal discharge using an LIFEPO it errors out. Finally figure out it was due to the current volts on the battery. So if I start the discharge with the LILO option it believe it has a good battery and gets moving... then half through that discharge I need to switch to my custom one that takes it down to 2.5 and then when i finished I have to start another task to charge it all the way back to 4.2v Have you found any way around this where the charger ignores the current volts? Or any way of performing a normal cycle on this LIPO 8-9AH similar to Liito Kala or Opus test mode where it charges first and then discharges and back again recording the amp hours accepted by the battery? any suggestions are greatly appreciated.

Can you tell me what happens if you set the nicd discharge program to auto and are using multiple nicd cells? It seems to work with one cell, but I am not sure how it detects the correct lower voltage when using multiple cells

Hi Richard, very helpful video thanks for posting.

My just acquired Imax B6 (clone) is giving very inaccurate discharge test results - 2/3 or even half what they should be. I actually returned a couple of new 18500's to the seller for them to check, they tested ~ 1200mAh, seller confirmed capacity of ~2000mAh. Is there a way of callibrating an Imax or fixing this?

For storage - Whats the difference between using the discharging function to discharge the lipo to 3.8V and using the storage functionality to discharge it to 3.8v?

This really helped me.
Thank you.

I get err when trying to charge my Li on after I discharged too low. What happened ?

Hello Mr Richard, well explained, I having confusion am having 32650 LiFePo4 batteries, I would like to balance the batteries with I Max b6 charger, question is I can charge 6 batteries at one time, when it comes to discharge as I saw video they are saying that I have use one battery to discharge, I request you to please explain how to balance the 32650 LiFePo4 batteries possibly a video, thanks in advance

Will this discharge 2.4 LTO cell

Indeed, the ONLY discharge profile that lets you modify min (discharge-to) voltage is NiCD.

The default min discharge voltage for LiFe is way too low, at 2V. Needs to be more like 2.7.
So, to be able to safely discharge LiFePo4, you select NiCd and set the discharge voltage to 2.7.
You'd then use that profile (NiCD) when doing the discharge excersize. Don't forget to switch back to proper mode when doing charging.

Set the profile to NiCd, discharge voltage to 2.7V, discharge current to 2A, connected my cell (LiFePo4) and started the discharge.

It only went for 11secs before current dropped to 0.0 Amp ! Why ?

Guess what ! All of these (the original and the clones) can only handle 5W in discharge mode.
It needs to be able to dissipate that much power internally, and due to its smaller size, can only handle the 5W max.

In my case, single LiFePo4 cell being @ 3.2V, I can only discharge at max of 1.5Amp, so that A*V=P stays under allowed 5W of power.

When I set that limit, discharge current to 1.5A, discharge started working as expected.

If you want to discharge 2 cells, then the current needs to be halved and so on.

I would like to know what amp do you use to put in storage one lipo 2700mah 7.4v 10c battery?Also what amp do you use to charge this battery?

So i have a GENUINE imax b6, I gently charge them 1x to 4.18v @ .5 amp, i discharge 18650's to 3.0v at .5a, get a mah count HOWEVER I notice that after this the battery is still at 3.6 volts :( I also use a ZB2L3 cheapy discharger board with 2 resistors BUT it takes em down to 3v or really 3.14v. One NASA Utube guy says the ZB2L3 is NOT accurate. I did a shootout comparison using matched cells from a laptop battery, both had same voltage, charged em up, took em down a bit, recharged to 4.2volts, split the 2 cells and discharged one imax other ZB2L3 and they were within 2% in their mah rating, BUT how can this be when Imax seemingly leaves tons of voltage in the cell???? I'm thinking the C rating may differ between cells. Also i will charge and discharge in 2 cells, pre connected via the laptop packs (reclaimed with at least 2.volts otherwise they get sorted out later) with nickel strips, however i am sure to keep em around .5 amp charge or discharge per cell wether ZB or imax. comments, thoughts, suggestions welcome

can someone please help me with the correct setting to charge a 5400mAh LiPo 4K 3S 11.1V 3C LiPo Battery ?

I need a clarification if you charge and discharge Lithium-Ion(18650)cells like liPo, I think were a missing some capacity, I'm right or I'm missing something
