Cell Pro Powerlab 6 help

denver commuter · Aug 2, 2015

Hello my e bike friends! I am hoping someone can help me track down a replacement part for my Powerlab 6. I was getting ready to charge my batteries like I've done several times and there was a pop from the charger and the magic smoke escaped. I tried to catch it to no avail. It will still power on and cycle trhough the menus but as soon as I try to start a charge cycle it gives me an error. After taking the charger apart I found what I believe to be a fried FET. I cannot get the numbers off of this part, I've tried looking at it outside, from different angles, upside down, I've even had my kids look at it and we can't make out any numbers. If anyone knows what this is or what I should order please let me know.

where is it located in the circuit and can you post up pictures so we can see where it is connected? is there a similar mosfet adjacent in an identical circuit?

http://www.revolectrix.com/ Have you tried contacting these folks or someone affiliated? Perhaps your charger is still under warranty. Even if your charger isn't under warranty still I imagine they have the information you need and maybe even the component as well.

I did contact Revo and I believe they will probably take care of it. I use this everyday for my commuter set up so I can't really afford to have it down. If I can fix it quickly vs sending it in and taking weeks I would rather fix it.
I will get pics of the whole board and post them up.

More pictures.
The fet is almost right behind the C19 marking.

is the drain of Q24 attached to the negative output to the pack when charging?

denver commuter · Aug 2, 2015

It is connected to the positive. At least I have continuity when I connect the fet with positive cable and a multi meter.
I am fairly new to all of this electronics stuff but I'm learning quickly! When people mention drain I think of 1 1/2" copper tubing, solder and torches so this is a shift for me.

if the drain is connected to the positive then it is an nchannel mosfet. so something beyond the 6S in voltage would work but use a mosfet able to handle the current.

the irf3205 is good to 55V as i recall. cheap on ebay. i may still have one. i do have some irfb4110 also.

My typical charge is 4s6p so I would think either would work?

dnmun · Aug 2, 2015

i just assumed it is only 6S from the title since we never saw the entire balancing charger.

LOL. The charger is in a few pieces at the moment.
Would you be interested in parting with any of the gets you have?

i will look for a 3205 since they are only 55 cents as i recall. the 4110 were $2.50+ from patrick.

sent you a pm for the irf3205 and p75nf75.

Got it thank you. PP sent.

3205 in the mail.

Ok I received the FET and installed it with no problems however the charger will not even turn on now. When I hook it up to the server power supply the power supply goes into protection mode, if I try to hook it up to my meanwell there is a spark and nothing else.
I think I may be out of my depths here. If anyone would take a look at this for me I would appreciate it. Just send me a PM or post here.
