You don't want what you think you want. Apples and oranges with different SoC behavior by design.
G1 Insight = NiMH with a tendency to seek higher SoC with 10 voltage monitoring points. NiMH has some limited tendency to "balance" north of 70% SoC.
Optima/Sonata use pouch-type LiPo. They swell rapidly at higher SoC. Car holds them closer to 50% SoC in most cases and monitors each of the 72 cells. The battery BMS has limited battery balance capability but does so all the time.
