You know it honestly has gotten to such a great point to start upgrading hybrid batteries that I'm surprised people are still disabling the ima batteries on these cars.
Does anybody know what depth of discharge the OEM battery is designed to stay within on the bms? From the specs on Honda's website its 144V 6.5Ah battery. That's really only 80 18650 battery cells and you could do a couple packs of 40 cells to get whatever Ah pack you want. Similar to what Tesla does with 3350mAh 18650 cells. The cool part is that 80 cells weighs less than 8 pounds for the cells themselves and you could configure this pack to have so many cycles of capacity depeneding on dod that it would pretty last indefinitely (if configured to stay between 30-70% discharge the panasonic cells in the model 3 have a 40,000 cycle life). I don't know much about the oem pack. Does it have a battery fan, battery warmer?
