for my project, I'm getting down to soldering, and I ordered a 14.4v 5Ah pack of C cells from batteryspace to run my overvoltaged 35w project. I will post some pics very soon. When y'all say "overvoltaged 35w is rough on the AA batteries", this means ??? They drain pretty fast and get warm, okay, but does this just mean they will die faster? Or, will they light up the night in a large ball of flame?
Stupid question: is it not adviseable to throw in some variously charged odd batteries laying about the house on top of my bike light battery pack (not exceeding the smart charger's max capacity).
Yes, for small batteries (low Ah rating) high current draw will shorten their life. For a detailed description go
here. For your pack, you are pulling 2.4A from a 5 Ah battery which means you are drawing about half the battery capacity per hour. This is actually a pretty comfortable amperage draw for a rechargeable. If you were using a 2.5 Ah battery, you'd be on the edge. If you were using AA batteries (1.3Ah), you'd be killing them in no time flat.
Heat, whether on charging or discharge, is the enemy of nearly all rechargeable batteries.
