Current selection for PowerPump balancing circuits

PK14234
Prodigy 60 points
Other Parts Discussed in Thread: BQ78PL114

I've read through the PowerPump Balancing app note and the bq78PL114 datasheet, but I haven't seen any information regarding the selection of an appropriate balancing current for the charge pump circuits. Is there a rule of thumb to follow, like a certain % of the total battery capacity?

    Bump, still looking for this information. I'm working on a 7S 20Ah pack, charging at a 1/3 C rate and discharging at a 1 to 2 C rate. Trying to determine a proper balancing current to complete the design of the power pump circuitry.
