 +    * PDO2 tx: looks like battery voltage or charge. Decrements when powered and increments when charger connected. 
 +  * canopen.node_id == 0x02 and canopen.function_code == 0x9 
 +    * PDO4 tx: increases when charging decreases when resting, could this contain a temperature? not sent as often as the other messages (1 per 2 sec) 
 +  * canopen.node_id == 0x02 and canopen.function_code == 0x3 
 +    * PDO1 tx: again something that increases when charging and decreases while standby and even more when powered. could this be battery voltage?
