Hello, I received my Pine today and am now looking for a suitable LiPO battery that fits the discharge and most importantly, charging specs of the board. Going over the schematics and the PM datasheet, I now have several questions. The battery switch/monitor/charger in the AXP803 has register-configurable and thus software controlled settings. The charge current limit can be set to anything between 200-2800mA and the cut-off voltage between 4.1 and 4.35V with several other additional parameters. Since selecting a battery without knowing the default settings the software selects for those registers is outright dangerous... are those registers controlled by a Linux driver for the PM or are the default register values still in place after booting up?
Come have a chat in the Pine IRC channel >>
