Safety & Handling

  • Use only Li-ion 58.8V CC/CV chargers (supplied).
  • Do not short, reverse polarity, or charge below 0°C.
  • Do not disassemble, crush, or expose to fire.
  • Store cool and dry at ≈ 50% SOC if unused > 3 months.
  • Avoid water immersion and direct heat sources.
  • If you notice any swelling, odor, leakage, or deformation stop using immediately and contact support.

How to maintain the battery?

The battery should be stored in a clean, dry, ventilated environment at room temperature. When unused, keep it at 30–50% charge and recharge it every 3 months to prevent over-discharge.

Charging Instructions

The charger's indicator light will display red while the battery is charging. Once the battery is fully charged, the indicator will change to green. Full charge takes approximately 7.5 hours with the included 2A charger.

How to prolong your lithium ion battery?

Recharge your batteries before they are completely dead.
After every 30 charges, allow your lithium based battery to completely discharge before recharging.
If the battery cannot hold a charge even after proper charging, it may be time for a replacement.
