Recently I won a contest over at the Lasonic facebook page. They sent me the new 931BT blaster. I'm really digging it for several reasons. It was FREE and whats not to like there? Haha! It's pretty rugged and it's not rare or expensive so it's a great blaster to bring all over this summer and not worry about. It sounds pretty decent for what it is. It's definitely LOUD! As BBB said, it does have better bass output than the earlier iPod Lasonics. Also, despite not having chrome I think it looks awesome! It's the tough guy of the current collection.
So, I wanted to make this my hassle-free, always ready, beach/skate blaster of 2013! That way I can keep all my vintage babies safe and sound under controlled conditions at home and unleash this beast when I'm out and about. Lets face it. I will still bring my other boxes out, but sometimes I just want to have some crankin' tunes without needing to obsess over a rare grail. :D
Here's the plan. I found this baby on ebay:
Output voltage: 12.6-10.8V DC.
I did some tests with a smaller capacity lead acid battery and everything went fine so I'm assuming this Li Ion should be ok. Think this'll work out?
The box already has a 12V DC jack on the rear panel as seen below:
My goal, is to wire the battery pack inline with the 12V DC input. Therefore I'd be able to charge her up using the stock jack. I will just be able to switch the existing power selector from DC to AC to take any load off of the battery. This will allow for a totally easy solution for keeping this thing juiced up without having to worry about about alkalines all while keeping the appearance oem.
This should be pretty straight forward as far as I can see. Am I missing anything? WHat are your opinions? As Norm will tell you, I use the common sense approach to this kind of thing. Any type of "actual" electrical theory is beyond me.
