  1. Not sure that I'm seeing the same battery hookup information you are referencing - link specifically says 2 kWh (3.7V nominal * 21 cells *26Ah = 2.02kWh). I think that this one is 1/2 (say 3.3 kWh but that’s based on nominal voltage) of a full C-max Energi HVB. Ford marketing probably used fully charged cell voltage - 4.2V * 48 cells * 37Ah = 7.46 kWh I almost got stuck figuring out how to take two of them and rebuild my own 2014 Energi HVB. Electric only range had dropped from 25 Miles (New 2014) -> 18 Miles (2019 - 80K miles ) -> 15 miles (2020 - 92K) all with no HVAC. Dealer I bought it from kept telling me that ‘all was well’ even though cell testing showed they were maxing out at 3.9 V and the once I found the MyFordMobile app, it was telling me I was only getting 3.3 kWh from a full charge. I would have frequent Yellow wrench warning lights on from 2017 on and it took a few tries for the dealer's service techs to understand _and_ let me know that the errors presented when the yellow wrench was on disappear when the car was is turned off and not available via the standard ODB2 command set. They replaced the charging port, battery control module (2x), charger cooling elements, entire wiring harness and late in 2020 (97K miles), finally got Ford to agree to replace the battery. Luckily, I had paid for a 10 yr/120K Ford ESP so I ended up paying only the deductible -$100. Range with the Ford refurbished HVB went up to 22 miles - yeah! I spoke to the shop foreman about a year later who let me know Ford charged $23K for the replacement HVB - told him to check out BatteryHookup or they could subcontract the work to me… The good: Car has 110K and drives 20+ miles/day since 2014 on full electric - averaging 57 MPG overall Drives great and handles western NY winters fine with snows Dealer always had a newer loaner than my car when I had to leave it for service The bad: Dealer didn’t really have anyone except the shop Foreman who knew hybrids/plugins Service techs and service manager kept telling me the electrical issues were due to my Level 2 home charger - I had to explain that the Cmax ‘charger’ circuitry was onboard the car and all my charger did was be a big fat extension cord Kept the car in service for ~ 1 month/year from 2017-2020 Passed up a 2015 Energi for my kids for $5K two months ago - now they’re $15K on Carvana
