i have a refurbished solar steet led
it has a good charge controller .but i suspect night time LVD(low volt disconnect )does not work well
cant repair it.

i want to add an external Lvd
1)it must cut off when battery is 11v
2)act as deactivated during day

please suggest a circuit

iam thinking for day....i can do it with 2pc bypass diode(to reduce the drop)
