Specifications

Setup

1. Power Connection

• AC Power: Connect the supplied AC power cord to the AC input port on the rear of the charger (Figure 3). Plug the other end into a suitable AC outlet (100-240V).
• DC Power: Alternatively, connect a DC power source (6.5-30V) to the DC input port on the rear of the charger using an appropriate cable. Ensure correct polarity.
• The charger will power on and display the main interface.

2. Battery Connection

• Connect your battery's main discharge lead to one of the XT60 output ports on the front of the charger (Figure 2).
• For LiPo/LiHv/LiFe/Lilon batteries, also connect the battery's balance lead to the corresponding balance port next to the XT60 port. This is crucial for safe and balanced charging.

Operating Instructions

1. Navigating the Interface

The HOTA S6 features a color display and a scroll wheel/button for navigation. Rotate the wheel to scroll through options and press to select.

2. Charging a Battery

1. Connect the battery as described in the "Setup" section.
2. On the main screen, select the desired channel (CH1 or CH2).
3. Choose the battery type (e.g., LiPo, LiFe, NiMH) from the menu.
4. Set the cell count (e.g., 3S, 4S for LiPo) or voltage for Lead Acid batteries. The charger may auto-detect, but always verify.
5. Set the desired charge current (in Amps). Refer to your battery's specifications for safe charging rates (typically 1C for LiPo).
6. Select the charging mode (e.g., Charge, Balance Charge, Fast Charge, Storage). Balance Charge is recommended for LiPo/LiHv/LiFe/Lilon batteries to ensure cell voltage equalization.
7. Confirm the settings and start the charging process. The screen will display real-time charging data.
8. The charger will automatically stop when the battery is fully charged. Disconnect the battery once charging is complete.

3. Discharging a Battery

The charger supports internal and external discharge. Internal discharge is suitable for smaller capacities, while external discharge allows for higher power dissipation.

1. Connect the battery.
2. Select the discharge mode from the menu.
3. Set the discharge current and the desired cut-off voltage.
4. Start the discharge process.

4. Storage Mode

For LiPo/LiHv/LiFe/Lilon batteries, using the storage mode is crucial for prolonging battery life when not in use for extended periods. This mode charges or discharges the battery to a specific voltage level (e.g., 3.85V/cell for LiPo).

1. Connect the battery.
2. Select "Storage" mode.
3. Start the process. The charger will automatically adjust the battery to the optimal storage voltage.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the charger's exterior. Do not use solvents or abrasive cleaners.
• Ventilation: Ensure the cooling fan and vents are free from dust and obstructions to maintain proper airflow (Figure 4).
• Storage: Store the charger in a cool, dry place when not in use.
• Cable Inspection: Regularly inspect all cables and connectors for signs of wear or damage. Replace any damaged components immediately.
