There is a bug inside the python script when the chemistry type is not set.

Unlimited bat runtime (I need this but clean shutdown when bat is empty) :

(root|~/PiModules/pico_status) i2cset -y 1 0x6b 0x01 0xff

I need to set LiPo on Stack/Top/Plus version ? Documentation is bad what is the non-Stack/Top Plus version ?

(root|~/PiModules/pico_status) i2cset -y 1 0x6b 0x07 0x53

or

(root|~/PiModules/pico_status) i2cset -y 1 0x6b 0x07 0x50

?

Documentation is too random for this product. It's very hard to get clear information.

(root|~/PiModules/pico_status) python pico_status_hv3.0.py

133.333333333 % WTF ????

Never convert a voltage to a bat percent !!!! you must use current integration + auto-calibration algorithm to get the a real bat % like any smartphone or laptop !!!!
