Sorry if these all have been documented somewhere, but also wondering about how will the PCB 1.4 handle 4A charging? The INA169 had a bridge I could solder on and it was able to handle up to 5A charging. Batteries have max 4A charging allowed so I have been using a 4A charger on my mowers. Will 4A charging be a problem now??
PCB 1.4 no INA169, how will PCB 1.4 handle 4A charging

Hello @markor,
at the PCB1.4 the INA is integrated on the board:
For a charging current up to 5A you have to close the red marked bridge (JP16) by soldering and you have to replace the T3A at EF1 against a T5A or T6.3A fuse.
If you use the Sunray Software, you have to change the following settings in the config.h:
