It's been a little while since we last heard from the folks at Boston-Power, who've been touting their better, safer laptop batteries for over a year now, but it looks like they've been doing anything but resting on their laurels, and they now seem set to step up their game in a big way. Helping in no small part on that front is a $45 million infusion of new funding they've just announced, which brings the company's total funding to date to a cool $68 million. That announcement also just so happens to coincide with word that the company's sealed a deal with China's GP Batteries to significantly ramp up production of the batteries. According to the company, the partnership with will allow them to increase their production capacity by two to three times over current levels, and churn out over a million Sonata battery cells per month by the end of 2008. There's still no word as to exactly when they'll be available to the general public, however, but as before, all indications point towards HP being among the first to offer 'em.
