I need a new headlight and want to go for something more than a 'be-seen' light. After doing some searching and some reading, I think the MagicShine 900 fits what I want (no proprietary batteries, nice and bright, low price).
However, I'm a little wary of any of the pre-built packs being sold with it by various people, so I'm interested in putting together my own pack so I can charge the cells separately (to avoid problems with them becoming unbalanced). What brands and suppliers should I look at for the batteries, for the charger, and for the holder? I'm not sure what's a good compromise between cheap and not junk. Oh, and for the first round I'd like something I can get faster than DX, or preferably any of the other HK dealers. I don't want to wait that long to be able to ride in the dark, after work.
Also, I'm not new to electronics and soldering and such, but I've never build a battery pack before. Are there any special considerations I need to know about? (For instance, if I go with unprotected cells, what extra precautions do I need?)
Finally, someone else said this was the right part to mate with the connector on the MS. Is that right?
Thanks for any help!
