hi empulse owners my name is gio and I just bought a empulse r. It's a defective bike it wouldn't charge anymore. That's how I came to this forum. I was a mechanic for 20 years and mechanical/elektric runs though my vains. When I diagnose the bike I realize one of the seven batteries wouldn't charge (top front). The rest of them voltage I could get 14,5+. So I took the battery out and opened it up. First I opened the bottom part and saw that some cells were bloated. That's problem nr1 After that I opened the top and saw that it had some corrosion damage one 3 transistors. I will bring the print plate to a specialist for repair. After this I could pull the top of to seperate the cell pouches. It was a little hard because they were bloated. Cut some fingers while doing so. But it all worked out. I measured all cells and they were flat. So I'm looking for new cells. The specs I found were 10ah 3.7volt 3/5c li-on pouches. I found some suppliers in China who could make them. But I'm still looking for something closer to the Netherlands /Europe. My plan is to leave the battery as much as original. I will try and upload some pictures of my progression when I'm on my computer. Don't know how this works on my phone. |
so today i feeled a little bit better i was sick for a week and started to look at the empulse again.
i charged 6 of the 7 batteries ( one is bloated as seen in pictures below).
The all hold there voltage so it seems that i only got one faulty battery.
I didnt get the pcb back yet and i also didnt find the wright size pouches.
The pouches i need are Lithium NCM pouches 10ah 3.7 volts with a dimension of 2450x158x10 these are realy hard to find.
Most of the pouches are lipo or lifepo , if i replaced all packs then i would try the lipo but i only want to replace one for now i still need to look if the empulse doesnt have more defaults.
If someone knows someone with a complete oem battery or good poouches please let me know.
I also downloaded the files of the usb to my pc but it seems that the converter isnt working on my pc and i cant get it to work.
Last file registerd was from 4-2022.
I will ad a link of the last few files on the bottom the complete file is 3gb.
someone who can convert it for me here?
