I had to upgrade my headlamp to the newer model (black diamopd Icon 480 lumen lamp) of my favorite manufacturer. It is the direct replacement for my previous model. I assumed it would have the same battery plug for a rechargable pack they sell (it was like $70 for a tiny LiPo so they were making $$$$!!!) but this only accepts 4 AA's. It seems they aren't lasting very long and I'm tired of wasting them.
So, time to make some upgrades and add a LiPo. Last model I had ran on 3 AA's and a 6v pack (had a voltage converter chip) as well as a 5v DC input (also lacking on current model).
So, I'm kind of stuck trying to figure out what battery will be best for this application. I can find a 3.7 or 7.4v battery that will fit inside. I'll either need a boost converter for he 3.7 and possibly a buck converter for the 7.4v pack - either will need to be pretty small.
I'm not sure how much current this headlamp draws at its highest settings, probably less than 1A @ 6v. Is it better to go with 3.7v and boost the voltage or 7.4 and a buck converter? Do you think it would be a problem trying to run the device at 7.4 v? I know a freshly charged 7.4v pack may actually be 8.0-8.4v as the "max charge voltage".
Anys suggestions on what would be the best solution for this? Also, is there a way to add a DC plug input on a device like this? (it is currently waterproof so the connector must be fairly small - it doesn't need to be a traditional round DC jack, any connection that would work is acceptable). Thanks for any suggestions!!
