A brief description first.
I've got 16 LiFepo4 cells all connected in series for (nominal) 48V.
I have a monitor that will activate an alarm or trigger a relay on EACH cell. (pos & neg)
I'm thinking of having the relay close contacts on high voltage (preset at 3.6V DC) and to connect another set of heavier wires from the high cell to a 100w globe or similar to drag down that cell while at the same time disconnecting the solar charger. It will be run through a timer that controls the relay. I'm thinking a 3 minute setting initially before it reverts to globe off & charging restarting.
OK....... my question is whether I can run all of the heavier wires through diodes so I only need one globe. It is very unlikely to ever have 2 at HV at the same time. Remember each cell has two wires from it. Not a common earth.
For those that don't know.... these cells won't equalize or 'self balance'.
By keeping the high cells down the charger will control things by itself nicely.
Thanks for your input!
