Battery Pack build for flash triggers need help !

[AkshayK]

Hello All,
Has anyone used 32700/32650 6000 mah batteries 3.2 v as battery pack to the flash triggers ?? are they reliable as the 18650s ?
Could anyone share their pack photos and whats done ? I was thinking of using a single 32700 3.2V lipo battery or 2 18650 lion batteries in parallel with a charging module and a dropdown buck cconvertor to get 3v for the trigger.

Regards,
Akshay

A couple years ago I wanted to extend the life of the flash trigger receiver. So, I came up with this circuit and board. It removes power to the flash trigger during the day, extending the battery life. In this configuration the 18650 will last a couple of weeks.
