24volt rechargeable drill conversion

[Ian Bosman]

Advice please from those who are a bit more technical. I have a 24 volt rechargeable drill which is long obsolete which I am converting to run off 12 volts with a transformer to up the voltage to 24v from 12v. I have converted one old power pack already. So far so good but what I want to do is use it with the motorhome with the odd jobs sometimes. I did look at buying new cells for the power packs I have which have dead cells but the cells are costly to buy. Anway, I am now thinking about how to source the 12volt in the motorhome, one option being to run it directly off the leisure batteries sourcing and installing some terminals in the back end garage where the leisure batteries are or to buy a mains power pack giving me 24 volts dc say at 10 to 15 amps (I am unsure what current draw from the drill) using an inverter which I have (300watt). From what I read a PSU from the mains would draw 1.5amps. The terminals in the garage are my current favourite but the leisure batteries are a bit of pig for access as they sit fair and square underneath the middle of the lower floor, (the upper floor is the habitation area) and the height means laying inside the space to gain access.

What do you intend to use the drill for? Small holes in the van, or drilling concrete on your house/garage/barn ?

It must be easier and cheaper to simply buy a 12 volt drill or even a 18 v one

I was going to suggest the same depending on the answer to my question above

Small 12v motorcycle battery, dc to dc converter, wire it up with enough slack so you can leave the battery on the ground while holding drill overhead. Or visit Aldi/Lidl.

What Terry said..
I went to a loadof bother to install an external 12v socket and converted an old 12 v drill to run off a lead from it.. it was to make my
Kayak carrier winch a bit easier to use..
In the end it just didn't have the torque to operate the winch.. but a good quality 18v battery one does the job..

What you're planning is going to be very restrictive..... Basically converting a self contained battery drill to a 12v corded drill.
An 18v drill with two batteries is peanuts in Aldi/Lidl.

Lidl have B&D drills in the middle isle.
