Different Size Batteries In Parallel. The parallel interconnection must be accomplished with. Sorry to comment on such an old post but i wanted to clear this one up When you connect 2 batteries in parallel they equalise between each other We already know that the voltage equalises but what happens is that if they have a different level say one is at 100 and one is at.

The intermixing of battery packs is a reality and in fact one of the benefits of modularizing batteries in standard form factors and with standard specifications. Uncertain about what to buy. Connecting in parallel increases amp hour capacity only.
One battery provides 15 volt.
For example you can see that the actual size of the RELiON Group 24 is 1024 x 661 x 858 and is slightly smaller than all the subgroup dimensions. We would strongly discourage anyone from connecting batteries in series or parallel applications if the batteries are not identical in age size and type. My plan was to squeeze in a 110 Ah battery in the original box and then put a battery of the biggest physical size into it around 140 Ah capacity and connect them in parallel. My gut reaction is that mixing two sizes.
