Introduction

The Blueye High Capacity Battery V2 (model HCB2) is a 216Wh removable battery that provides up to 5 hours of diving time. It can be charged while installed inside the drone or directly with the Blueye charger.

As the battery capacity is more than 100Wh, it is NOT allowed as a carry-on item on airplanes, according to the lithium IATA guidance document. It needs to be carried as cargo in accordance with the IATA Dangerous Goods Regulations. A copy of the UN 38.3 manufacturer declaration for the HCB2 is attached to this article — bring it along when travelling, as some airport staff might ask for it.

What's new

The V2 battery improves on the original high capacity battery:

Capacity increased to 216Wh (15.0 Ah), up from 212.4Wh.
Maximum continuous discharge current doubled to 50 A, up from 25 A, giving more headroom when running power-demanding payloads.
Maximum charge current raised to 20 A, up from 5 A.

It keeps everything introduced with the first high capacity battery: a built-in battery checker with status LEDs, flat surfaces to prevent it from rolling, and a solid handle.

Runtime

The battery has a capacity of 216Wh, providing a runtime of about five hours in light conditions. The capacity is more than twice the capacity of the standard battery, so if you use a Blueye standard battery today, you can multiply your average runtime by 2.2. The weight remains the same as the standard battery, so trimming the ballast is unnecessary.

Charging

With higher capacities comes longer charging times, so we recommend using our second-generation charger when charging the high-capacity battery.

The improved charging speed only applies to batteries charged directly in the charger. Charging inside the drone will provide similar charging speeds to the old charger.

Battery status LEDs

The LED pattern shows the battery's current state of charge. The LEDs use a combination of solid and blinking lights to provide as accurate state of charge as possible.

LED1 blinking: 0% to 12% charge
LED1 solid: 12% to 25% charge
LED2 blinking: 25% to 37% charge
LED2 solid: 37% to 50% charge
LED3 blinking: 50% to 62% charge
LED3 solid: 62% to 75% charge
LED4 blinking: 75% to 87% charge
LED4 solid: 87% to 100% charge
