So, I have an opportunity to buy a 48 volt hilo battery dirt cheap, this battery is at as local business that is out of business, it was an extra battery for a hilo that has been sold, the charger went with the hilo, it would not have been of much use to me as it was 460 volt 3 phase, the thing appears to be in as new condition, the guy that wants it gone has no information on age or use, if I do decide to buy the thing, I'm going to have to borrow a friends hilo as it is one big heavy motor scooter, any advice on what I should do as far as testing it would be appreciated, i'm building a 17 foot 48 volt battery charger.
Now, the magnet question, I got my 3x1.5x.75 magnet today, these things a scary strong, I've never dealt with magnets like this before, what would happen if one of these came into close proximity to a cell phone or a hard drive? Will they affect the magnetic stripe on a credit card?
