unfortunately I only have one charger. And yes, actually I want to try it. But I don't know how many volts when fully charged and how many volts if it needs to be recharged. Can you tell me about it? Because I get 18V in multimeter, you can see it on video. What it means under volt and must be recharged? Or defects on the pcb?

If I did that, they would check my battery. But I was a different country. I was not going to return. Due to shipping problems and different countries. So I want to solve this problem before buying a new battery

I have p107 lithium battery 18v. Now i can't use it because if i charging it will be testing mode "red blinking". I showed my problems in this video. Thanks for helping
