driver options for 11.1v battery

octaviusthefish · Mar 19, 2009

I am trying to drive a single xr-e from a 11.1v li-ion (i want an 8 hour battery life at around 700ma output. I am not finding many options for small drivers (not buck puck) that have a sufficiently high max input. Can multiple drivers w/ lower inputs be connected to allow for a higher V battery? or- could I link a 7.4V and 3.7V battery in parallel or series and then use one or more drivers that have lower max input? Does this make any sense at all?

thanks in advance!!

I assume you are using 3 li-ion in series (3.7v x 3 = 11.1v). Do you have to use 3, and what is the application. If you can wire them in parallel, you would be looking at more cheap driver options.

Get this dropin and remove the driver

Works fine with a 11.1v Li-ion battery pack, or you could keep the driver and just upgrade the led as I did to a Q5, it has 5 modes, Lo, med, high, strobe, SOS

Just my .02
