How do I charge and store the batteries?Updated 2 months ago

LiPo batteries require more care than other battery types. Follow these tips to ensure their longevity:

• Charge the batteries fully only right before your session.
• Never leave batteries completely empty or fully charged overnight, as this can shorten their lifespan.
• If you won’t be using the batteries for an extended period, set them to Storage Mode (2–3 LED lights). 
• Perform a full charge cycle at least every 3 months and then set the batteries back to Storage Mode.
• Remove the batteries from the charger as soon as the charging or discharging process is complete.

Charging the batteries:

1. Switch on the charger.
2. Insert the batteries into the dock (check + and -). The batteries must be switched off.
3. Press the round buttons on the charger.

Charging or discharging to storage mode (2 or 3 LED lights):

1. Switch on the charger.
2. Insert the batteries into the dock.
3. Turn on the batteries.
