Features 1、Generator Charger: Allow the starting motor to be started while the battery is being charged by the mains, automatically identifying the voltage level of the charged battery pack, and then automatically charging according to the battery voltage level. 2、Constant Current Fast Charging: When the voltage of the charged battery is lower than the set value, 12V battery pack <12V, the charger quickly charges the battery with the maximum constant current. 3、Current Limiting: When the charged battery is close to full charge, 12V battery pack ≥ 12V, the charging current is automatically limited. 4、Float Charging: When the voltage of the charged battery reaches the float charging set value, approximately 13.8V for a 12V battery pack, it automatically transitions to the float charging state, charging at a current of approximately 0.1‑0.2A, depending on the current consumption of the powered equipment at that time. 5、Stop Charging: When the voltage of the charged battery reaches the charging set value, 14V at 12V, the charging output is automatically turned off. 6、Secure Protection: The product has comprehensive over current and short circuit protection. Due to its constant current feature, it will not be damaged in the event of a large battery capacity, extremely low internal resistance, load short circuit, or simultaneous starting of the starting motor during mains charging, when the starting current is very high, it is close to a short circuit for the charger. Meanwhile, due to this characteristic of the product, the charger does not need to be disconnected when the battery is used as a starting power source.
