I bet $10 the POP charger is getting cancelled anyway. Those guys really felt like they were just looking for a reason to cancel their kickstarter.

I am Jamie Siminoff the inventor of POP. We are in the process of confirming if the changes that Apple PR told the press are true. If they are then POP will be made and I look forward to delivering it to all of the doubters out there. @Devilboy, I hope you order one as I will hand deliver it and take that $10:)

I'm curious, are you going to apologize for calling them assholes in print?

What an interesting story. Project goes awry and recovers by using the refund story to build interest for new venture. Apple sees hand and raises. Users throw down 4 aces and collect giant pot of cash. Sounds like wins for everyone.

Earlier quoted context omitted.

These days you can get a single chip that nearly does all the "battery management" for you. example: http://www.microchip.com/wwwproducts/Devices.aspx?dDocName=e...

The example that you've given is is a single cell, linear charge management controller. For a 26Ah (what voltage?) LiIon (LiPoly?) pack you need a lot more than that. Balancing, temperature monitoring, overcharge/over-discharge protection, current limit.

That isn't the only chip microchip makes for recharging, but it's probably the cheapest. There are more complicated (larger) chips that do everything from overcharge protection, temp monitoring, etc. Some applications don't need all that fancy stuff. The chip I linked is 4 years old, but they make new versions of the chip almost every year.
