Dual-pack parallel lithium battery pack
This paper presents the effect of modeling uncertainty of a lithium ion battery pack on the accuracies of state of charge (SOC) and state of power (SOP) estimates. The battery pack SOC is derived from the SOCs of all parallel cell modules in the pack, which is computed using a sequential estimation process. SOC and SOP estimates are essential for …

how to wire dual bms lifepo4 packs in parallel
I have a DIY build question. Building a solar generator with 2-280ah lifepo4 packs. Each has its own BMS. I want these to be in parallel. I understand that you hook pack 1 positive to pack 2 then use the positive of pack 1. You do the same for the negative, but the BMSs are my question. Do you connect pack 1 BMS negative to pack 2 battery neg ...

Batteries In Series Vs. Parallel
If you connect two 12v 50ah batteries in parallel, it will still be a 12 volt system, but the amps will double to 100ah, so the batteries will last longer. On the other hand, when you connect batteries in series, voltage is increased while capacity (ah) stays the same.
