Rob Danielson: > ... I'll try to pull the collective insights together... I bought a bunch of the 9v battery connectors and hotglued 6 of them into a housing and wired them in series. 5 alkalines and another shorted connecter give you adequate voltage when the batts are fresh. Six connectors lets you use NiMh rechargables that don't generate full voltage. You'll want a good battery tester that actually draws some current (not just a voltmeter) to weed out the weak cells. One cell going bad renders the other 4 or 5 useless. -- Mike ________________________________________________________________________ ________________________________________________________________________ |
