Cheap broken tools off eBay and scavenge the mount?

Cheap broken tools off eBay and scavenge the mount?

One possibility, for sure.

You appear to be able to buy 'faulty' tools for around £30.

But then, how to know if its not the battery mount that is 'faulty' ?

Unlikely compared to other bits that fail. Usually gearbox or motor first on the cheap ones, then battery...

For same idea but probably better batteries I'd go Makita or De Walt.

Might be worth trying local
recycling centre too.

And should be less than £30: I expect a lightly used but fully working Makita of the now old fashioned brushed motor type for that!

If using 36v battery's rewire the units with 14 or 12 awg wire , if wanting more ah current wire two in parallel.

So that adapter plate can be used for the 36V batteries, if the wires are upgraded ?

 

[Nealh]

The specs claim 14awg so the wire is capable of more then 10a if it is silicone awg.
If the wiring isn't silicone then change it as the silicone awg handles heat better plus is highly flexible.
One assumes the battery footpring for 18v &3 6v is the same except for a larger battery stack size with the latter.

But does the holder for an 18V battery also fit a 36V battery ?

It will do if the two batteries are identical in fitment and share exactly the same foot print.
