Skyelmad Posted May 3 Share Posted May 3 You can but first check charge voltage and float voltage are the same or very close as not to overcharge or under charge any. You'll have to choose "USE" on battery type and set voltages according to battery specs. Preferably just 0.3v lower Currently I've paralleled AGM with Lithium. No issues at all. You won't have communication with the inverter Quote Link to comment Share on other sites More sharing options...

You won't have communication with the inverter As you are using AGM with lithium the same can be done with other lead acid batteries but the lead acid does suffer as they normally don't charge to 100% but it does work. Very interesting to see how the lithium carries most of the load up to a certain level before the lead acid kicks in. As far as Paralleling different batteries the OP must just ensure they are the same tech and also the same number of cells. 15 cells cannot work with 16 cells.
