The data is determined according to the battery type
2. The above data is 12V battery data, if the main battery is 24V, all parameters
need to be multiplied by 2.
Short flashing: Voltage is normal (1time/ 5 s)
Fast flashing: Over-voltage(HVD) (1time/ 1 s)
ON: Low-voltage(LVD)
Battery
full
Off: No charging
Short flashing: Boost charging stage (1time / 5S)
Fast flashing: Constant voltage stage (1 /1S)
ON: Battery full
Off: Not charging
Short flashing: Lithium battery does not charge
below 0
℃
(1time/2S)
Fast flashing: Over-heat inside the controller (1 time/S)
ON: Charging (B2B charging or PV charging)
Slow flashing: Reduce current charging (battery
temperature>50
℃
or <-20
℃)
(4s ON and 1s OFF)
Off: No D+ signal, no charging
Flashing: Start battery voltage < 11V (1 /5S)
(B2B mode: <10.8 stop charging,
>12.5V, resume charging
Fast flashing: Start battery voltage>16V, (1time/S)
ON: Start battery voltage is normal (11V-16V)
