uhtrinity has posted about his parallel setup... after recal his Insight makes use of the 8ish Ah it has from two packs... I don't think anyone yet knows how high the Honda BCM will adjust for Ah capacity of a pack....

If it is based on the hardware limits of the memory used in the BCM then it should be following the binary pattern... so 8Ah works, if it goes above that then 16Ah would be next and 32Ah after that etc.... if it will track the Ah of your 45+4 = 49Ah combined capacity then that would mean it might go as high as 64Ah.

If it is software limited it could stop adjusting for higher Battery Ah capacity at any point.... but uhtrinity's test show it at least gets up near 8Ah.

Although I personally still prefer the other connection points that Mike has been using at the MDM posts to the Battery... This combined with Current limiting controls makes a nice Boost system... the boost systems supplied current offsetting current that comes from the IMA battery... and the BCM tracks the IMA battery as designed to... In order to make the boost battery safe you add a separate BCM of your own design to the booster battery.... a PHEV charged boost battery will not mess up the BCM or cause recal.
