Charging a second auxiliary battery

2 Monate ago

I’ve currently got a 1225d hooked up to a solar panel and my alternator, charging a 100ah lithium battery. I was with wondering if it is possible to unhook the 100ah hour in order to charge a second 20 ah lithium battery from time to time. I was hoping to be able to do this during the day while the solar panel is inputting to the 1225d? Is this interrupt and swap okay with an active solar input?

Hi Jack,
Thanks for your post.

This will be fine, no problems there.
One thing you will need to check is that the smaller battery can handle receiving up to 25A charge current from the BCDC. See if you can find a 'recommend/nominal charge current' specification to ensure it will be fine.
Otherwise you should be good to go!

Best regards,
