Why not get a few good rechargeble d-cells instead?
Because that would be silly. First off, it is mad expensive:
<a target=new class=ftalternatingbarlinklarge href="http://www.bydusa.com/product.asp?3=46">4 D Size NiMH 8000 mAh Batteries + V-1199 Universal Quick Charger
Sale Price $45.99</a>
Second, the whole idea is rediculous. You should not have to charge batteries in order to charge your other batteries. Its unbelievably innefficient.
Thrid, the D-Charger only takes 4, and you need 6.
I bought the DC Peak charger for just $15 from a local hobby shop (also saw one on Ebay for that price). It works fine for charging the Stealth battery, and plugs right into your car's cigarette lighter.
