+ | The more challenging task is judging when to kill the circuit based on voltage **under heavier loads**. | ||
+ | |||
+ | - apply expected load | ||
+ | - run battery down to 11.5v (then 11.25, 11, 10.75, 10.5 etc until battery no longer rebounds to 12.1-12.2v) | ||
+ | - remove load | ||
+ | - observe battery voltage | ||
+ | |||
+ | If the battery rebounds to the desired voltage then repeat to deeper discharge. | ||
