Key Specifications

How Does an 84V 10A Battery Charger Work?

The charging process follows a multi-stage charging algorithm:

1. Constant Current (CC) Stage

• The charger supplies a steady 10A current.
• The voltage gradually increases as the battery charges.

2. Constant Voltage (CV) Stage

• When the battery reaches 84V, the charger maintains the voltage.
• The current gradually reduces to prevent overcharging.

3. Trickle or Auto-Shutdown Mode

• The charger stops charging when the battery reaches 100% capacity.
• For lead-acid batteries, a trickle charge may maintain the battery.

Features & Benefits of an 84V 10A Charger

1. Fast & Efficient Charging

With a 10A output, these chargers reduce charging time while maintaining efficiency.

2. Smart Battery Management System (BMS) Compatibility

Most Li-ion and LiFePO4 batteries use a BMS for protection. This charger is BMS-friendly, ensuring safe operation.

3. Built-in Safety Features

These chargers include:
? Overvoltage Protection (Prevents exceeding 84V)
? Overcurrent Protection (Limits charging to 10A)
? Over-temperature Protection (Shuts off if overheated)
? Short Circuit & Reverse Polarity Protection

4. LED/LCD Indicators for Charging Status

Many models come with LED or LCD indicators to display:

• Charging in progress
• Fully charged
• Error warnings

5. High Durability & Cooling System

• Aluminum casing for better heat dissipation.
• Active cooling fan for temperature control.
