I have a BMV712 with 2 100ah lithium batteries connected in parallel. My Progressive Dynamics, PD9360 charger has a nominal output of 14.4 volts, and idles at 13.6v. Should my charged voltage be bassed on the nominal output of the idle output, and should it be based on one battery, or two. If I set the charged voltage basedon my nominal output, should it be 14.2, or 28.4 since I have two batteries, and/or, should use idle output and set at 13.4 or 23.8? TIA! ---

Im sorry, pd9360. Progressive Dynamics. I don’t have any flights planned. Lol ---

😄 The pd9360 converter coverts from mains to a 12v system. So i am going to assume you have a 12v system. > [@bilco82](#): > > Should my charged voltage be bassed on the nominal output of the idle output I assume you mean on the bmv here. What battery chemistry do you have? > [@bilco82](#): > > should it be based on one battery, or two This usually only affects capacity (AH) unless you are connecting them for higher system voltage. Which i am assuming you aren’t because of the converter output. ---

The charged voltage is slightly below absorption voltage but above float. They are in parrallel so the voltage is the same. ---

You have a 12v system, so it will be 14.2v > [@bilco82](#): > > LiFePO4 batteries connected in parallel. You don’t add voltage in a parallel conected battery set up. ---

I disagree Ludo. When its your own system, you should move fast, break things, and learn fast. ---

> [@bilco82](#): > > should it be based on one battery, or two I understand what parallel means. I was told recently that since I have 2 batteries I should double the charged voltage. I didn’t think that sounded right since I don’t have a 24v system so I found this forum and asked an expert. Thank you for you for you concern. ---

Great advice, RP. Thank you! ---

If you want to learn, have a look at Victron’s [Wiring Unlimited.](https://www.victronenergy.com/media/pg/The_Wiring_Unlimited_book/en/index-en.html) ---

You have double the capacity, but the same voltage. The only\* thing that changes when you put more batteries in parallel is the capacity, but the charger doesn’t need to know the capacity. One setting that you might want to consider is called tail current on a Victron, might have a different name for your charger. - actually of things change, but few are relevant to this discussion
