Limitation on simultaneous commads LTC3300-1

Hello,

The LTC3300 is designed to be able to balance all 6 cells at a time. Typically a cell monitor is used in conjunction with the LTC3300 to determine which cells need to be charged and discharged. As the high cells are discharged, the charge is places back on the stack and will be distributed back to the to the cells. It is possible to actively charge the low cells while discharging the high cells. Larger stacks are typically broken up into groups based on the ability of the monitor, number of cells, etc. It is feasible to have a single monitor for all 16 cells or use 2 separate monitors. Either way it is feasible to balance all cells at the same time. Please keep in mind that balancing is an act of charging and discharging. Discharging all cells simultaneously or charging all cells simultaneously does not make sense because the charge needs to come off of the stack when charging or back onto the stack when discharging. Below is the link for the DC2100B user guide which has much information on balancing battery stacks using the LTC3300. Please also look on the ADI website for more information on the LTC3300 and battery monitors.
