G-400 Charger
This 400W charger features high efficiency and reliability, and is suitable for a wide range of global voltages. It can charge lead-acid batteries (flooded, AGM, and GEL), as well as lithium batteries.
Product Characteristics：
Overvoltage and surge protection
Standard USB function for downloading charging history data, updating charging curves, and firmware upgrades.
Digital display for real-time monitoring of the charger’s status, including AC input voltage, charging status, and fault alarms.
The charger is equipped with multiple charging curves built-in, which can be adjusted via buttons to match various battery types.
Automatically charges when the battery voltage is low, and automatically disconnects when the battery is fully charged.
The optional CAN bus function allows communication with the vehicle or lithium battery BMS, and the optional handle function is also available.
Application Field
Common Mode(Default) & BMS Mode
The charger enters BMS mode when being connected to lithium-ion battery through Can Bus.
For safety reason, the charger will flash “bnS”if being reconnected to Lead-acid battery under a BMS mode.It means no communication, no power supply.
Insert the AC power into the charger, the charger will only charge Lead-acid type battery again if we refresh the charger through USB port with the desired lead acid battery charging profile via USB drive.
Press & hold the Select button for 3 seconds in BMS mode to release the curve number, that is, switch back to normal mode. Press & hold the Select button for 1 second to choose the desired profile (Optional function).
Universal applicability
With detachable AC and DC able interfaces, for various voltage ranges around the world, it is capable of charging lead-acid batteries (Flooded, AGM and GEL), as well as lithium batteries.
Efficiency up to 93%
The G series delivers over 400 watts (depending on the specific model) of pure power, utilizing incredible thermodynamic principles to provide the most compact and powerful industrial battery charger ever. We not only use heat sinks, but also design a precision-machined, aluminum unibody that maximizes airflow and enhances thermal capacity.

New industry standard
Professional and precise design. Manufactured for durability. This industrial battery charger is made to perform even in the toughest and harshest operating environments. Whether used as an onboard or offboard charger, its durable aluminum unibody design can withstand impacts and vibrations, allowing for hours of continuous operation. Its over-molded stress relief mechanism prevents unnecessary strain on the cables while providing a waterproof seal.
Vehicle locking function：
Prevents the electric vehicle from moving while charging, thereby preventing accidental damage to the connected wiring system. The suppression port contains a 30A relay that closes and disables the vehicle when connected to AC power.
EQ function：
Through EQ (Equalization) charging, the internal imbalance of the battery can be corrected, ensures that all battery units are fully charged, thereby eliminating imbalance and improving overall battery performance while extending its lifespan. An automatic EQ charge is performed once a month on flooded batteries, and emergency EQ operation can be triggered via the IOS button.
Power supply mode：
The power supply mode transforms the industrial battery charger into a constant current, constant voltage power source, which is used to check whether the charger itself is faulty.
Protection function：
Industrial battery charger are exposed to some of the harshest and most extreme operating environments.Whether for onboard or offboard applications, these chargers are designed to be impact-resistant, vibration-resistant, waterproof, and dustproof, with an IP66 protection rating.

Optimization：
By optimizing the internal specific gravity of the battery and stabilizing the internal chemical composition, improving battery performance and extending service lifespan.
Maintenance：
Powerful battery maintenance charging feature monitors battery activity to keep the battery fully charged.
Function：
The perfect charging curve should be provided based on the battery information to achieve precise battery charging.
Recovery：
When detected, it applies a high voltage and low current charge, causing the battery to be sulfated and converted back to the active material, thus restoring the lost battery capacity.

Safety：
Prevent reverse polarity, overcurrent, open circuit, short circuit, overheating and overcharging.
Firewall：
We don't design things to just work, but to remain safe in the event of a major failure. That's why we've built in redundancy levels of security.
Opportunity Charging：
Intended to recharge the maximal amount of energy while the electric vehicles are not in use - lunch time breaks or intermittent use.
Warranty：
Our battery chargers are built to last. That's why we back it with an unrivaled warranty and combine it with unmatched customer service.
