$195USD is pretty steep. I don't find myself needing to charge 4 batteries at the same time but it might be a good investment for a field owner as a service to their customers, or, if you're a complete gun whore like some of the photos I've seen in other threads.
The claim of it being the 'smartest battery charger ever' should be backed up with some technical data so the consumer can make that decision. I've posted all the data on my chargers (

Pokie, unless you understand the need for LiPo power regulation, stick with NiCAD or NiMH. Improperly used Lipo's can burst into flames, damage your gun and hurt you if you discharge them wrong.
