Amps are what a battery is drawing from the charger. You will see the voltage is higher on the top pack, meaning it came with a higher charge than the lower one. None of that means much at all. Check the individual cell voltages. That will mean much more.Just picked up to new 6S batteries. The top one I just noticed does not show any amps. Bad battery I assume? It is a power hobby battery.
I also don't know if it necessarily came with a higher storage charge. The top one has been charging for an hour and a half while the lower one had only been charging for a half hour. I'm guessing that this is a 50 or 75 watt per channel charger with it taking so long to charge.Amps are what a battery is drawing from the charger.

Good eye and valid points! I didn’t even look at the time on the charges.I also don't know if it necessarily came with a higher storage charge.

As @Cheapbastard & @Mr.Duke said, the amperage will drop way down as it gets closer to completion and it looks completely normal.
Yep, with a 5000mah 6S pack, you would need minimum 5A and 111W per channel to charge at 1C. Even if it's capable of 10A, it will hit the wattage ceiling which appears to be 75W, so your not going to get much over 3A out of it. You need a pretty healthy charger to deal with 6S. 10A/150W per channel for packs under 7000mah to be able to at least charge at 1C.Good eye and valid points! I didn’t even look at the time on the charges.
It appears to be a 150W total output on AC. That would give you about 75W per channel, and when charging at 25VDC, that’s a max of 3A. While I don’t know his batteries mAH rating, assuming it’s 5000mAH, that’s gonna be a loooooong charge. 3000mA/H would take almost 2 hours to charge a 5000mAH pack from empty. Forget anything larger than 5000mAH ??

I know I mentioned this in another thread but should the cell voltage not be 4.2v? All of the other calculators use 4.2v per cell that I have seen. Also you have to take in account the inefficiency of the psu in the charger which at best is 80%.Yep, with a 5000mah 6S pack, you would need minimum 5A and 111W per channel to charge at 1C. Even if it's capable of 10A, it will hit the wattage ceiling which appears to be 75W, so your not going to get much over 3A out of it. You need a pretty healthy charger to deal with 6S. 10A/150W per channel for packs under 7000mah to be able to at least charge at 1C.

I normally use 4.0 per cell. When the battery is close to 4.2v per cell the charging is slowed way down, so you aren't pulling full power. At 4.0-4.1v per cell the charger is normally still charging at full power. 4.2v per cell does give you a little more of a buffer when figuring out your needs though.I know I mentioned this in another thread but should the cell voltage not be 4.2v? All of the other calculators use 4.2v per cell that I have seen.
Oh I missed that, sorry on my phone and it is being kind of dumb today.I normally use 4.0 per cell. When the battery is close to 4.2v per cell the charging is slowed way down, so you aren't pulling full power. At 4.0-4.1v per cell the charger is normally still charging at full power. 4.2v per cell does give you a little more of a buffer when figuring out your needs though.
Also, if you scroll to the right there is the 4.2v section.
I have 4.2 and 3.7 in my chart.I know I mentioned this in another thread but should the cell voltage not be 4.2v? All of the other calculators use 4.2v per cell that I have seen. Also you have to take in account the inefficiency of the psu in the charger which at best is 80%.
I have 4.2 and 3.7 in my chart.
I know my chargers all drop current significantly around 4V, so I could probably augment my chart by setting it to 3.9V per cell to get a better idea.
