First off great site and I have read many of the hovercraft threads but am still in need of help.
My 11yo wants to build a small battery powered remote controlled hovercraft for a school project. I want to keep as hands off as possible but am concerned that he might blow up a battery without some guidance from folks on AAC.
What we have thus far is an array of batteries and a dozen computer fans of differing amp draw but all 12v DC.
The batteries are as follows;
1 x 12-volt 3.0 Amp hour NiMH pack. See link below

2 x 12-volt 1.5 Amp hour lithium-ion. See link below

4 x 18-volt 1.9 Amp hour Ni-Cd Battery. See link below

Bunches of Alkaline 9 volt like go into a smoke detector
Bunches of Alkaline and NiMH AA batteries
6 12v fans are out of desktop computers with amp draw at 0.7,1.2, 1.4, 1.6, 2.5
5 12v fans are out of a rack mount server and are about 1/3 the size of the PC fans and draw 1.6 amps
My main concern is that he could blow up a battery and I would rather he learn about these things vicariously. In the same vain I want him to gain a good understanding of batteries and how to properly plan for there use in devices but here is where I seek your advice.
What questions should I ask him to answer for himself so he can properly and safely plan the power plant for a hovercraft?
Thank you kindly -- Pippin
