I want to combine two RC LiPo packs in parallel, in such a way as they form a single battery, rather than two batteries connected in parallel.
I've had a good read of this thread: https://www.endless-sphere.com/forums/viewtopic.php?f=14&t=52240
Based on the excellent description, I created a sample wiring diagram for the creation of two parallel cables for two 3 cell RC LiPo packs:
- one parallel power output (and charging input) cable
- one parallel balance cable
I've attached the diagram below.
Since these are LiPo I thought it would be a good idea to check that I have understood things correctly, mainly for the balance cable. My understanding is:
- The parallel balance cable connects each end of the two pack cells together, in this order: + to +, +/- to +/-, +/- to +/-, and - to -.
- This is sufficient to create a two cell parallel grouping for each pair of cells
- This will equalise the voltage of the pairs of cells while discharging
I would really appreciate someone validating my understanding, and telling me if I'm wrong! Not having an runaway fire trumps my ego every time
