Does anyone know if it is ok to combine a Pila 168s with a SF123 to use in a SF 9P with the 3w LED drop-in? I don't want any problems mixing types. Thanks for any info. /ubbthreads/images/graemlins/help.gif
To expand a bit, the Pila battery's voltage is around 3.7 and the SF123's about 3 volts. If you mix them, the Pila will try to charge the SF up. This could result in overheating and could trip the protection circuit in the Pila.
