Hi newbie here, in my motorhome I already have (1) lion battery, 12v-100 amp, I have bought a second battery, same make, same 12v-100 amp, can I connect it to my smart 12-12-30 charger, or would it be safer to add a second charger? thanks James.
You should be able to connect the two batteries together.
Is that how you plan to use them?
The charger will charge both just slower. Just don’t connect tham at different states of charge.
Hi, thanks for the reply, and yes I will connect the two batteries in paralell, one battery with the positive lead the other battery the negative.
