Yesterday I ran my new 10s6p almost flat (4% left). This morning 14 hours later its only 88% full. I think thats hell of a long time. Is that just the way it is (with the charger I have) or could there be an issue?
What would be a good upgraded charger? EDIT: if I want a bad mother fucker that can do tricks.
Specs:
Battery: 10s6p Samsung 18650 30Q.
Charger: Output 2A
Battery cut off: start 32V end 30V
Charged inside
Need more info?
You have 18ah, there’s a good chance that charger isn’t delivering a full 2A so I would say it could be right, also if one P was higher than the rest it could slow down charging till the rest catch up and it wouldn’t hurt to double check wiring, make sure everything is solid
Especially with large packs those chargers can get quite hot and lose efficiency, not to mention horribly skinny leads
A true 2A charge with CC/CV for 18Ah should be about 12hrs
That is to low if you ask me… I run mine down to 35v max, and with voltage sag and when you hitting a hill they often run down arround 30v for short periode of time… Check that the cell voltage between the cells stil is spot on.
Also you Will lose capacity a lot faster, when you run them down like this.
Ok - I might fund the issue. I turns out that the plug is a tight fit and I was afraid to apply the force needed to make a proper connection. It was dangling and I had to secure with tape for it to not fall out. Its actually fits good. Lets see if that effects the time.
