Hey thanks fechter for your input. I am just using the laptop charger by themselves in a split pack battery pack. Battery pack when connected to ebike is 10S10P, when I charge I split the pack into 5S10P suitable for the laptop chargers voltage of 19.50 or close to it. Not the ideal 21V for 5S (x2 s...

Re: Normal non cc/cv PSU with a normal cc/cv charger to increase volts and still get cc/cv charge to battery

Intersting Note

I used the good laptop charger to charge half my pack to 19.42 that is my battery pack right now.
The "bad" laptop charger reads 19.72V
DMM reads 19.50V with batt plugged into charger and slowly increasing, normal.
Unplug charger, dmm on charger stays at 19.72V and does not decrease.

The second I thought I messed it up by touching the two outputs of the charger and it just would not charge. I opened it up and began searching,...

I just bought a cpl hun 25R from nkon to ship to Canada, they say 3 weeks and most get 3 to 4 weeks.

Next step is to hook up them heating pads and insert temp sensors inside the pack. I was thinking Ardruino or a clone.

Re: Best place for replacement computer battery ?

Be careful, some of the batteries communicate with the laptop through onewire protocol, not an issue for using charger to charge any ole battery. I guess that central pin is easily damaged and shorts out, maybe some of the generic batteries would not take that 3rd wire into account. I just finished ...
