Hi I recently acquired a number of Prius battery modules (Gen. 2)
Each module is rated at 7.2v 6.5AH
(according to: http://www.endless-sphere.com/forums/viewtopic.php?f=14&t=6726 )
My post is actually a two-part question. Should I (1) throw money at it and buy a good charger, or (2) should I attempt to build something with parts I have laying around (I tend to lean towards the latter )
Buy it:
Can anyone recommend a charging product for these modules? Like an R/C charger? I have no experience with these R/C chargers so any recommendations would be appreciated.
I suspect going this route and just buying a charger is probably better than my home grown ideas ( keep reading)
Build it:
For now I have several wallwarts laying around. Including a wallwart 7.5v, 600mw power supply. Using this along with a timer set to disconnect after ~ 10.5 hours, I could have a crude charger for very cheap.
I also have an old laptop power supply with 16v 4amps that I was thinking of using as well for charging 2 at a time (wired in series ).
I'm thinking of eventually creating a dV based setup as seen here.

When the voltage exceeds a tunable threshold, charging is stopped. But will a dV based approach be accurate for these batteries?
