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.

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 are dangerous when not used properly. Improper operation and maintenance can also severely shorten battery lifespan. Please read and understand all the information in the Blue Robotics Lithium-ion Battery Guide to ensure you are using Blue Robotics batteries safely and getting the best performance out of your batteries.

  • Only use battery chargers designed specifically for lithium-ion/polymer batteries.
  • Do not charge a battery above its maximum voltage. This will lead to battery explosion.
  • Do not discharge the battery below its minimum voltage. This kills the battery.
  • Do not exceed the maximum charge or discharge rate. This will damage the battery.
  • Do not get the batteries wet. A wet battery may short or will eventually corrode and fail.
  • Do not puncture, crush, cut, or disassemble the batteries.
  • Do not burn or expose batteries to temperatures above 50°C (122°F).
We are unable to ensure that users follow correct battery charging, operating, and maintenance instructions. For this reason, Blue Robotics cannot be held liable for any loss, damage, or costs which are incurred as a result of incorrect operation of our products.
