dnmun wrote:he is measuring the resting voltage of a fully charged pack it seems. i think i recommended he discharge the pack into a dummy load and find out which cell dies first and he can measure the capacity by running the discharge through an ammeter setting on his voltmeter if he doesn't have a wattmeter or cycle analyst.
dnmun wrote:it would help to find the weak cell that triggers the LVC. i thought that was your problem, maybe you are a different problem, several limno4 battery pack threads floating around now.
dnmun wrote:adjust the charger voltage up and see if it will give you the capacity you are missing then.
dnmun wrote:can you be more specific about where the short occurred? is the BMS now shut down? what is the gate voltage on the output FETs? you may still be able to adjust the charger voltage up to see if that gives you the full capacity.
dnmun wrote:you shorted the output of the charger or the output of the battery? i have no idea where the 3 prong connector is.
the gate on a mosfet is like the toggle on a light switch. when it is high then the mosfet conducts and when it is low then the mosfet is shut off and acts as an insulator.
do you have pictures?
