Ping Lifepo4 Charger on 14s 18650?

[V_Mark]

I just ordered a 14s (51.8v) battery made from 18650 cells. It will be coming with a charger, but I was wondering if I could use the King Power charger for my Ping 48v lifepo4 battery to leave at the office for charging at work. The Ping charger indicates that it outputs 60v, but I'm not sure how accurate this is. I know that 58.8v will charge 14s up to 100%.

Will this kill my battery?

The 5 amp ping charger ( kingpan ) is adjustable thru a trim pot.

I did some searching and I see that now. I'll definitely attempt this. One question though, I believe that the charger doesn't kick on unless it's hooked up to a battery; I'm not sure if there would be any output if I just connected it to a volt-meter. Would I have to connect it to the battery to measure the output voltage? If that's the case, will accidentally turning the pot the wrong way damage the ping 48v by providing too much voltage?

Get a volt meter and plug in the charger and find out. Put it on a higher voltage then needed, the meter. You will answer your own question. I use a meter that's set properly.

My old king pan chargers from ping, you just put a voltmeter on it, and diddle the screw on the pot till you see what you want to charge to. I have mine set now for 13s, at 54.6v

I made a screwdriver out of a bamboo skewer. Plus turn very slow. My ping had 63v caps. I ran it to 72volts for 4 weeks. It popped the caps. I replaced with a 100volt cap and have it as a travel charger set to 84volts. It's 6years old hard to believe. I don't know if my 100volt cap fix is advisable.

It appears you have found and replaced the weak point (voltage wise). If nothing else turned to smoke I'd say you should be fine.

How to keep the smoke in ?

Thanks for the help everyone. One more question -- Which way to lower the voltage, clockwise or counter-clockwise?

 

[V_Mark]

This worked, thanks! I was able to turn the pot near the fuse clockwise to lower the voltage to 57.4. This should give me a 90% charge on my 14s 18650 pack.

Since this charger was originally sold for LiFePO4 charging, is there anything to be aware of? Will the charger automatically shut off once the battery reaches 57.4v?
