You're very welcome. It is the most easiest PV I've ever used in my life with the variable wattage.
Each of my 2250 mah batteries last about 6 hrs at 9 watts on a 1.7 single coil carto BUT I remove charge them when the battery hits 3.6 volts cuz the Flashlight guyz suggest this for longevity. As for a charger the...
The very best- Sysmax/Nitecore/Jetbeam i4 Intellicharger
Intellicharge i4 Charger
Next best- Xtar WP2 II
XTAR WXTAR WP2II Charger - 2 Bay Charger for 14650 / 17670 / 18650 etc
Yes. Some even use them in their PV when the battery is too short.
You're prolly best to contact EddieAdams and buy some from him- Post # 46 or...
Magnetic Spacer - 1.6mm
For shorter use you'll need the
18350 X 800 mah batteries. When using stacked batteries you have to test them and use them in diff configs each time you use them. With the VV/ VW there's really no use to stacking as the PV would be the same length.
Always use unprotected with VV PVs as they have their own protection circuit. Protected "usually" don't work in a VV PV. You also want to make sure the batteries are "high drain".
Protected batteries are generally used in Mechanical Mods that don't have any protective circuitry.
