Best of luck ... just a few notes , you probably are already aware of.
Plan for the system to handle peak possible inrush current / power rates ... Although the packs change as they age , temperature, SoC/SoE , etc ... if you design for the end points of max and min , you will be best set.
AFAIK , the minimum net resistance for the whole OEM IMA NiMH pack all cells and connections is ~360mOhms ... V=IR ... the minimum OEM IMA NiMH pack voltage is ~120V ... the Max is ~187V.
So you can use those and the min max specs on the booster battery you are planning to connect , to get a reasonable prediction of the direction of peak current / power flow ... and the magnitude.
Then you will be in a good position to be able to either plan for / design the charge/discharge limiter you mention ... and/or ... chose when in what situations to use it.
Best of luck.
