Convert 12 VDC batteries to 8.4VDC

Hi tnk2k,

They are alternatives if you don’t have the energy to do it yourself! ;D

I agree with you tnk2k.

I'd just like to make a point about switching regulators, they are often cheaper than linear regulators because you don't need a large heatsink which is often the most expensive part of a linear regulator.

Hi Alun,

That’s a good point. Another thing about switchers is that they just need a few external parts and the complete circuit is very small in size and weight. A good example is a PSU I recently purchased, 13.8V at 20A which is one third the size of the one it replaced. The old one was a linear 13.2V at 15A and 6.5kg the new 1.4kg and it runs cool too.  8)
