Please Help!!! How do I connect & charge a single cell charger on my Ping lifepo4 battery?

Greetings,

First of all excuse my ignorance when it comes to batteries, etc. I currently have two ebikes but know very little about how to repair/charge the batteries using a single cell charger. I have a Ping lifepo4 48v 20ah battery. Ping recently sent me a single cell charger to assist in balancing the battery cells. Ping sent a diagram but I was hoping someone who has a single cell charger and a ping battery can post photos/video of how to properly connect it. I took the battery to a hobby shop and all they did was short circuit my bms for me.

I'll include a link to a youtube video showing the photos of the single cell charger connectors, diagram sent by Ping, and the new bms that I'm having a local electrician solder on for me, hopefully tomorrow.

Thanks in advance.

Re: Please Help!!! How do I connect & charge a single cell ...

As you may read from other posts Im not a fan of these fiddly BMS systems. You're certainly not alone in your problem.
If using a new BMS its odd that you would have to monitor single cells aswell, if I was doing that I would just get rid of the BMS all together then at least you would have access to the balancing wires!
Im not sure where Ping expects you to place those single charger clips when the boards still on the end of the white wires???

This may help

basically the nth and (n-1)th small wire corresponds to the nth cell. When n=1 or n=16 you use one of the Main power wires along with the 1st of 15th white wire
