Safety
Lithium-ion batteries can be dangerous if used incorrectly—and poor handling can also shorten their lifespan. To keep things safe and get the best performance, make sure to read and understand the Blue Robotics Lithium-ion Battery Guide before using your batteries.
- Use only lithium-compatible chargers with balance charge support and the correct cell count (4S or 6S).
- Never exceed a battery’s maximum voltage or minimum voltage. Overcharging = fire risk. Overdischarging = dead battery.
- Do not exceed rated charge or discharge current. This will damage the battery.
- Keep batteries dry. Water can cause internal corrosion or short circuits.
- Don’t puncture, crush, or open the battery pack. It’s not user-serviceable.
- Avoid excessive heat. Do not expose batteries to temperatures above 50 °C (122 °F).
- Do not leave batteries unattended while charging.
Because we can’t control how the batteries are charged, used, or maintained, Blue Robotics cannot be held responsible for any damage, loss, or costs resulting from improper operation.
