Re: Backup onboard charger not correct
I agree, I don't really like the circuit as well.

Can we modify the circuit? According to Rule <R63>, we are not allowed to alter the power pathway between the battery.

According to Rule <R56>, it states that we are allowed to use the custom charging circuit from IFI. Does that mean that we are ONLY allowed to use the IFI circuit? Can we use an alternative circuit, or modify the circuit (such as putting an extra diode at the 12V terminal to the circuit to prevent the 7.2V battery from driving the 12V electronics when the 12V power is off?)

Any help/clarification would be appreciated.

Thanks.
