The battery circuit seems strange to me. The liion cells would normally just be connected to output, without any transistors, because during heavy use, current goes very high, more than 20Amps and you would need very large heavy duty transistors. They can be used for charging circuit, of course, but this is not in use when running the tool, only when battery is in charger. Thus makes no sense to overheat and melt the solder on those components when running the tool. Unless the motor needs 18V or 42V and they used a 12V battery with components to increase the voltage, which is not good design.
If that component that came off is still working then you can most likely just some it back on and see if the battery works again. Personally i think that the part was just not soldered on well enough and got loose. I’ve pushed my ferm tools pretty hard so far and they work just fine. Not the best most accurate tools but they do what they need to do.🤷🏼♂️ You Probably just got unlucky by getting a bad battery.
Same problem here
Did you try it with a new battery and did it work again ?
I realised the battery is almost the price of the machine., so I didn't bought a new one
I love how you opened up the battery to show us what happened to it.
This is good for opening the box on the 20 inch gas saw you just bought.
where i buy another battery for this ?
They sell it at action shop, only way to expensive. I had the same issue a burned battery
Wow 3 screws holding that battery together?! I’m pretty sure the best M12 batteries only have 1 screw holding them together. Milwaukee take note!
Yeah well, Compare the quality of this one to a kids toy 😂
Where can I find to buy that battery?
Action has them only they are like 20 euro almost the price of a complete set
@@DennisDIY The price of the complete is 60e, so I only need batteries
I haven't seen them as a spare sold
@@DennisDIY I found it yesterday
That's nice, and at Lidl or other seller?
Too bad the battery failed! It's such a handy litlle tool- if it were to be designed well🙃

Very well. Explanation, thanks,

The battery is burned, a new battery is almost as expensive as the whole set
How much does it cost ?
It was around 39 euros, but I would not recommend it
Well this was for light branches not for an entire tree or 😂
Haha no, battery totally burned, of course for small branches it works OK
