Turbo is at work so i will reply. He took a decision to change over all of his tools to battery operation about 2 years ago and went mainly with De Walt. When he unloads his van at the weekend it is almost impossible to get into the garage. His battery tools include, chop saw, drill, torque screwdriver, circular saw with track, horizontal cutting multi tool, angle grinder, collated screwdriver ( had to look up the name, it is a the screwdriver version of a self loading gun), nail gun, jig saw and sds drill. He also has battery powered led lights and a radio which both run off drill batteries.
He will never go back to cable operated tools as he can now work on sites with no electricity and does not have to carry a big transformer for sites with electricity.
Strangely, although mains electricity over here is 240 volt, building site tools have to be 110 volt and big heavy yellow transformers are required for the operation of these tools. I am sure he does not miss dragging them around.
The battery angle grinder is particularly useful when fitted with 1mm cutting discs and has been borrowed on a number of occasions by our local tidy towns organisation to remove orphan chains and bicycle locks from lampposts.
However, when I wore out my old 3" angle grinder during the TRX300 refurb, he got me a mains operated one as he reckoned that a battery operated one might not be strong enough in the brake area for the abuse I would give it as I tended to run it for long periods at a time.
