The H6 PRO Lithium Battery Charger is a high-power lithium balance charger, perfect for use with all Blue Robotics lithium batteries! With built-in balancing and discharge capability, your batteries can safely be kept in top condition for maximum performance and lifespan! A nominal fixed 10A charge current means you can fully charge a high-capacity lithium battery like our
Lithium-ion Battery (14.8V, 18Ah) in about 1–2 hours. For even more functionality, the firmware can be unlocked to enable charging other battery chemistries at variable currents.
- You cannot add "Lithium-ion Battery (14.8V, 15.6Ah)" to the cart because the product is out of stock.

Safety
Lithium batteries are powerful and reliable—but they need to be treated with care. They pack a lot of energy in a small package, and mishandling them can lead to trouble. Before using the charger, make sure you understand your battery and follow the proper steps.
- Take the time to review the Blue Robotics Lithium-ion Battery Guide before use.
- Never leave a battery unattended while charging.
- Don’t exceed the battery’s maximum charge or discharge rate.
- Keep the charger on a hard, flat surface, and don’t block the cooling fans.
Charging with the H6 PRO Lithium Battery Charger
Important limitations:
- By default, the H6 PRO charger only supports 4S (14.8 V) and 6S (22.2 V) lithium-ion and lithium polymer batteries with at least 10,000 mAh capacity.
- DO NOT use this charger with other chemistries, voltages, or lower-capacity batteries unless you’ve updated the firmware.
- The fixed 10 A charge current is ideal for all Blue Robotics lithium-ion batteries and any 4S or 6S lithium battery ≥10,000 mAh.
Note on 6S charging: 6S batteries are only supported by default in R2 H6 PRO chargers with updated firmware. Older chargers need a firmware update—see the H6 PRO Firmware Unlock Guide for instructions.
1. Connect the Charger
- Plug the AC power cable (100–240 V) into the AC Power In port.
- Wait for the charger to boot up.
2. Connect the Battery
- Plug the XT60 to XT90 adapter into the Battery Port.
- Plug the balance lead extension cable into the Balance Port.
- Connect your battery’s XT90 power cable and balance cable to the adapter and balance lead.
DO NOT connect the battery to the DC Power In port. Doing so while the charger is plugged in can permanently damage both the charger and the battery—and may cause fire or injury.
3. Select Charging Parameters
Use the touchscreen:
- Select Cell count → Choose 4S (14.8 V) or 6S (22.2 V) to match your battery.
- Select Task → Choose one of the following:
Charge
Brings battery to full voltage (4.20 V per cell):
- 16.8 V for 4S or 25.2 V for 6S
- Use this for batteries that will be used immediately.
Storage
Brings battery to storage voltage (3.80 V per cell):
- 15.2 V for 4S or 22.8 V for 6S
- Use this if the battery will be stored for more than a day (for Li-ion) or a few hours (for LiPo). This helps maintain battery health and extends its lifespan.
4. Start Charging
- Select Start Task.
- The charger will beep and stop automatically once the task is complete.
- You can press the select button at any time to cancel the current task.
Safety first: Keep the charger and battery away from flammable materials while charging. Monitor the battery—if it gets hot or begins to swell, stop charging immediately.
