Hi all, awesome site you've got here!
Anyways, I'm planning on building a 100p14s bank to be charged off solar (60A Mppt controller).
Searching for a suitable cheap BMS is giving me a headache so I was thinking instead of a BMS I could just use low voltage alarms and high voltage alarms to let me know if my pack goes out of balance. Charge at 4.0V and set the alarm to 4.1V
I think I would actually prefer it that way since I can then fix the root of the problem instead of relying on balancing to "safely sweep the problem under the rug".
I've seen a lot of cheap low voltage alarms like these around:
Question is, where do I find equivalent high voltage alarms?
Or maybe it's possible to modify a low voltage alarm to become a high voltage alarm by just switching some wires around?
Seems like it should be fairly trivial to change the direction but I just don't know enough about electronics to even begin to figure that one out...
