    There are quite a few differences between these gauges. First you will need to know what type of batteries will be used. the bq78350 only supports Li-Ion, where the bq34z100-G1 supports Li-Ion, NiMH and PbA cells. The bq34z100 is just a gauge, so it does not support protection, cell monitoring, cell balancing, FET control, etc. The bq78350 is part of a chipset, so you will also need to use its companion AFE (bq769x0) The chipset supports all of the feature listed above. The bq34z100 uses the Impedance Track gauging algorithm where the bq78350 is CEDV.
