I know this is a stupid question but how do you connect 2 12 volt panel batteries to a firelite ms5ud
Reading the manual always helps. Consult section 2.3.2 in the panels manual.
Connect the red wire to the red terminal on the left battery, and connect the black wire to the black terminal on the right battery. Then, connect the two batteries together by wiring the black terminal on the left battery to the red terminal on the right battery.
They’re rechargeable, right?
Sealed Lead = rechargable, right? If so, then they should be.
You are correct.
