Re: PMEUMATICS

in series, and you could either get 2 x 7.2 volt packs but if your using drills i'd recommend over volting them with 2 x 8.4 volt packs for more speed

Re: PMEUMATICS

Re: PMEUMATICS

Wire them in parallel. That'll give you 14.4V and 2600mAh which will provide a more respectable running time. If you wired them in series you would get 28.8V, which is fine, but you would still only have 1300mAh and several speed controllers suitable for featherweights don't operate up to 28.8V

Re: PMEUMATICS

The answer isn't as simple as it may seem.

You'll need to know / work out the amps used by your setup....versus the amps your battery / batteries have to give during a given time.

Try playing with this calculator

..A Harbour Freight motor is probably the equiv of your motors.

Re: PMEUMATICS

One thing about wiring in parallel, you cannot charge them in parallel (as one pack) so you'll need to make sure you can unplug each pack to charge it seperately.

Not a bad idea using the batteries which come with the drills. We did that for our first feather which was more than enoug for the 30seconds it lasted before being retired as utter rubbish

It did last a lot longer running round the garden though.
