Hi there.. I have a question for all the battery gurus.. 
.. I need to power a portable 48v device pulling 100 watts (2.08a). To accomplish this, I want to purchase a four-pouch lead-acid battery belt used in A/V applications (seen here: The pouch contains four 12 volt batteries, which I want to wire in series to get to 48v.
The normal output of the belt is rated at 14.4ah @ 12v. Once I have wired them in series, A> how long will my device be powered on a single charge when pulling those 100 watts (and what are the calculations)?
B> what would be the best charging device for this configuration? (I was thinking a 48v scooter charger, but at what amperage would be best??)
and C> Does anyone have a better solution for this than the one I came up with? I would like to get at least 3-4 hours out of it
Many thanks for your time everyone
