Hi guys,
Did post this on another forum related to batteries and did not get much response.
Basically I have 16 ~3.2V LiFeYPO4 cells in a 48V arrangement. Primary aim is high and low cell alarm as its unattended. While the global battery high/low should work I have found they can drift and one or more cells hit the limit early. Outputs of the alarms will go into a picaxe I already have operating to kill load or solar regulator.
The AQV252V SSR is intended to duplicate the balance function that typical lithium battery management systems have but suited to the high current I can get from solar system.
Not all the crash hot with electronics so feel free to shoot holes in the JPG schematic attached. Or suggest a better method.
Obviously I have only drawn 2 cells monitors currently, rest will duplicate after tweaking. As an example to a cheaper SSR with the same pinout.
