That's a pack selection approach I understand 100%.

Today I installed my poor man's BMS - a remote set of six volt meters that I can plug into the car to monitor each 12V pair while I drive. On my commute home I quickly found out that I had a dud pair.
Woohoo!

As I was reading this, I was going to chime in and chide you about not having an "active" battery monitoring approach. Glad you've put something together. The LED battery pack gauge in the ForkenSwift is the key instrument in the car. Critical for preventing battricide of old, weak floodies.

I'm curious to know if the dud you discovered had been otherwise "hiding" behind an acceptable looking resting voltage.
