Husq 540iXP motor failure

[Bolt]

It’s only a shame that Husqvarna see fit to build their batteries out of something akin to fine Swedish crystal.

 

Maybe if they chose materials that weren’t so fundamentally brittle, customers wouldn’t feel the need to open ‘em!

@adw just for research purposes*, how much would you guys charge to undo 4 standard screws, switch a cracked bli200x cover for an uncracked one, and screw it all back together?

 

*asking for a friend 

 

Unfortunately I do not know what the dealers charge for labour, that is entirely up to them, to work on these batteries we need special cabinets, special benches, facility to dous the battery, special fire extinguisher etc, and dispose of batteries correctly, this all costs money, I do not write the rules just abide by them, lithium ion batteries can be very dangerous if handled incorrectly, yes you can take it apart,  and yes you may be perfectly capable to work on them, however they have Husqvarna written on them, so we just cannot condone end users taking them apart, if anything goes wrong I can just hear the legal arguments, and law suits now,”I was not told not to take them apart “

@adw Thanks, and yes, I would pretty much have assumed as much.

 

There must be tens of thousands of those types of Husqvarna battery out there now, so I assume that the demand for aftermarket non-oem battery parts will only grow over time.

 

I guess China will step into the breach at some point, with all the wide variety of QC issues that that entails…. Shame it’s not a nice little engineering company from the Midlands.

Have you checked the crank hasn't snapped?

Are batteries really that dangerous to fiddle with?

 

Short circuit could happen somehow if internal parts come loose damaged / bridged by something conductive?

 

Also suppose water isn't any good for battery fires as lithuim burns in water.

For fires involving primary cell lithium batteries, a Class D L2 Powder Fire Extinguisher should be used, this is a specialist powder extinguisher designed specifically for use on combustible metal fires which includes lithium metal.

I know I nearly exploded a phone battery once and had to run out of the house with it very nearly burning myself. It was like white phosphorous going off or something, exciting stuff 😃

My grandson's iPhone was on charge in the kitchen when it just started to swell up and blew the screen across the room. It was a few years ago now but still makes me nervous of leaving things on charge if I'm not there.

Yeah, I think many modern probably are really that dangerous to fiddle with.

 

There seem to be plenty of stories of batteries in scooters, hoverboards, phones or Boeing Dreamliners combusting because of poor design, poor construction, poor QC, bad chargers, overcharging, shorting or physical damage.

 

The fires generally go from nothing to proper white hot inferno in moments, are near impossible to put out, and are accompanied by horrific fumes.

 

As said, water only seems to encourage them.

 

I love ‘em, but at over £200 a shot, I have every intention of keeping my Husqvarna batteries un-combusted.

The rattling noise and lack of response could point to a sprocket issue, battery connection problem, or even motor failure. Check the sprocket, bar, and chain for alignment, ensure the battery is seated properly, and inspect for loose connections or overload protection triggering. If it’s a brushless motor, internal failure is possible but rare this early. Given your warranty, contact the dealer or manufacturer for repair or diagnostics, as premature motor failure on a pro-grade saw should be covered.

Rattling noises I found was the cooling fan has moved on the motor shaft and is now touching the outer cover, easy fix , remove all the outer screws and the left hand side just lifts off with the hand guard attached,then just press the fan back on, trigger issues are usually due to the magnet coming lose on the trigger.
