This Lithium-ion Battery (22.2V, 28Ah), fondly known amongst our team as the MEGA BATTERY, is designed for use in subsea vehicles powered by the T500 Thruster. It fits in our 4″ Series watertight enclosures and has enough power output and capacity for serious ROVs, USVs, and other vehicles! It has a QS8-S connector as well as an adapter for XT90S connections. Not compatible with the BlueROV2!

Lithium-ion batteries are powerful tools, but they can be dangerous if mishandled. Please take the time to review the Blue Robotics Lithium-ion Battery Guide before use.

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.

Product Description

The Lithium-ion Battery (22.2V, 28Ah) is a high-capacity battery pack made from high-quality Samsung 40T cells. We designed this battery specifically for use on vehicles powered by the T500 Thruster. It fits in our 4″ Series watertight enclosure and is equipped with a QS8-S connector that can handle the 110A continuous discharge rating.

This battery does not include an internal battery management system (BMS) to prevent overdischarging. The battery voltage must be monitored to prevent discharging below the minimum safe voltage level.

The battery can be charged with any lithium-ion compatible balance charger such as this one. It comes with a QS8-S to XT90 adapter to connect to the charger and also for use in low discharge rate applications.

The Samsung 40T lithium-ion cells used in this battery have excellent performance characteristics, as well as a high tolerance for accidental mishandling. The battery is CE (Conformité Européenne) approved, ROHS compliant, and UN38.3 certified. Certificates can be provided upon request.

This battery is not compatible with the BlueROV2 but it can be used with the BlueBoat. If using on the BlueBoat, make sure to get the 6S Battery Splitter Cable and follow this installation guide to set the correct settings.

The especially high capacity of this battery means that it is subject to more stringent shipping regulations than our other products. In addition to a hazardous goods shipping surcharge, we are also only able to ship this battery to a small number of countries:

  • Australia
  • Canada
  • India – Delhi, Karnataka, Tamil Nadu, and Telangana ONLY
  • Japan
  • Mexico
  • New Zealand
  • Singapore
  • United States of America (excluding Hawaii, Alaska, and Puerto Rico)

If you are located in a country not listed above, we are unable to ship this battery to you. However, our Distributors in the following countries are able to supply this battery in other parts of the world:

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.
