Battery Tube Upgrade Kit v2.x to v2.8

This set allows you to upgrade your OpenROV v2.5, v2.6, or v2.7 to have the battery tubes that come standard with the OpenROV v2.8. The 2.8 battery tube design features built in polyfuses, eliminating the need for battery tube adapters that are a necessary component for older model OpenROV's. The new design also has better mounting mechanism using high-strength rubber bands. This combined with new twist-lock endcap means sealing and re-opening the battery tubes is much easier.

These battery tubes are designed to work with our 26650 Li-FePO4 batteries and 26650 High Capacity Li-NiMnCo batteries.
