Wiring & Resistor Check Please
Hi,
Hoping folks could check out my wiring and resistor set up to confirm or advise. I think I got it, but it's a new area for me so any help is appreciated.
Here are the details.
NB V2 Board w/Power Extender
18650 3.7 3400mA PCB Battery
Red/Red/White Cree XP-E2 CopperNova
Red Vf 2.59V @1000mA (x2)
White Vf 3.15V @1000mA
2.1MM Recharge Port
Mom Tactile Switch 17
Resistor Calculation:
Red ? (3.7V - 2.59V)/1A = 1.11Ω | 1.11Ω * 1^2 = 1.11W (1.2Ω 1W resistor needed)
White ? Bypassing 2520 SMD (3.7V ? 3.15V)/1A = 0.55Ω | 0.55Ω * 1^2 = 0.55W (1Ω 1/2W resistor needed)
