I have a question for the battery gurus.. :).. I need to power a portable 48v device pulling 100 watts. To accomplish this, I want to purchase a four-pouch lead-acid battery belt (seen here: http://www.bescor.com/image/PRB24NC4459_Copy402.gif) containing four 12 volt batteries, and then wire them in series to get to 48v.
The normal output of the belt (total) is rated at 14.4ah @ 12v. Once I have wired them in series, A> how long will my device last on a single charge if it is pulling 100 watts (2.08a @ 48v)
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??)
Many thanks for your time!!
