Re: Back to old 12/24 question

As has been stated before, the main problem with going from 12v to 24v you 
instantly double the batteries you need to haul with you (weight=bad). You 
also double the amp draw, requiring even more capacitance to get the same 
run time.
However, I know a couple people who are wheelchair-bound. Their chairs run 
all day at 24v on what amounts to a big pair of car batteries. They also 
have the charging units built right in and the whole mess weighs less than 
200lbs, but who wants a tank that heavy?
When you double the voltage, you quadruple the power so pushing the extra 
weight isn't the problem. But at 24v, heat becomes a real issue. Also, 
doubling the speed means additional stages of reduction, adding more weight. 
And you would want to strengthen your hull to withstand the added weight and 
stress, all equaling a heavier tank.
24v components are a lot less common than 12v, and with the added amps, they 
become more expensive. Not to mention the cost of the additional batteries. 
But I'm sure sooner or later someone will do it. I'm rambling again aren't 
I?
