Nano Biscotte not going into sleep mode..
Hi guys. I've recently rewired by saber with a Nano Biscotte 1.0 so that it uses protected 3.7v 18650 batteries. My old (unprotected) batteries failed after 3 years of usage. I like to be able to swap out my batteries for a fresh ones so I thought I'd give protected batteries a try. I took out the PCB board and recharge port since I no longer needed them and wired the battery holder straight to the sound board. Everything seems to work perfectly, except the Nano Biscotte doesn't seem to go into sleep mode any more. In sleep mode, the battery can last for months, but at the moment, my batteries drain completely after a couple of hours WITHOUT turning it on, so I assume its still running. Anyone has any solutions for this? I want my NB soundboard to be able to go into sleep mode, conserving battery when not in use.
