Hey all,
I'm thinking of running my br off a 7.4v lithium polymer battery, but I had a couple questions before I start...
I've read a fair amount of horror stories involving LiPo fires and explosions, which I'd like to avoid if possible.
From what I hear, lithium batteries don't like being over or under charged, and they like to stay between 3v and 4.2v or so per cell... But, I'm planning on using one of BlueFusion's drivers from the gb, and as I understand it, these drivers will draw a volt, and the br diode will draw 4.5... SO... My question here is, is it safe to discharge one of these batteries to 5.5v without exploding?
The battery I'm using is one of these: https://www.dealextreme.com/details.dx/sku.7621
...which doesn't have a built-in limiting circuit afaik...
I've looked at buying one of these: http://www.all-battery.com/index.asp?PageAction=VIEWPROD&ProdID=1820
...which is a limiting circuit for a 2-cell lithium battery.. and should work fine, but it says the overdischarge cutoff voltage is 4.8v.. which seems really low, 2.4v per cell... Do I take this to mean it's safe to draw 5.5v from these cells?
Thanks!
