Used for inspecting cell levels and data logging for the original eVault battery.
Only for the eVault classic 18.5 kwh battery, not the MAX.
The eVault MAX manages these functions with the Fortress firmware update tool (sold separately).
Don’t buy this tool from us.
Buy it from Amazon because it will be cheaper and ship faster.
