What happens to excess power when a overkill BMS's max charge is set to 14.5v and the power supply is from these sources:
(For the sake of this question lets assume all the sources shut down at 14.6v)
1. A Progressive Dynamics 45a multi stage trailer converter set to the lithium with the included jumper ?
2. A desktop variable 30w 10a power supply set higher than the 14.5*
3. A 120w folding panel with the included cheapo PWM set for solar.
I am probably overthinking but will it harm any of the devises If their own shut off limits are not reached and they remain inline attempting to charge beyond the BMS limit?
4. * Can the desktop supply just be set to 14.5 and the BMS be left at the factory 14.6 setting to limit the top battery voltage for long term storage? Or will can the voltage in the battery ever exceed the voltage of a charging source?.
(If I do this for storage I can let the Trailer fully charge the battery to 14.6 when we are using it. That would actually be cool for max capacity when it's in use.)
I just don't understand how the interplay works.
I will ask how the chargers amperage plays into this as well later.....
