is a specialized, open-source software utility designed to interface with 15-cell and 16-cell (15S/16S) Battery Management Systems. These cell configurations are standard in 48V and 51.2V lithium iron phosphate (LiFePO4) and lithium-ion battery packs, which are widely used in solar energy storage, telecom backup systems, and light electric vehicles (LEVs).

Open the software and navigate to the connection settings. Select the correct COM port (check your Windows Device Manager if uncertain).

The jump to 2.0.6 isn’t a visual overhaul—it’s a stability and feature-squashing release. Here is the breakdown based on community feedback and changelogs:

Version 2.0.6 is not the newest version available, but it is widely considered the for the 15-16 hardware series. Here is why:

Your user account lacks access rights to the serial hardware port (common on Linux/macOS).

The "(15-16 Series)" in the software's name refers to its compatibility with specific lithium battery configurations:

Unlike active balancers, the hardware 15-16 uses passive balancing (bleeding excess voltage via resistors). v 2.0.6 gives you granular control over the balance current (usually 30mA to 80mA depending on your shunt resistors) and allows you to force balance manually, regardless of voltage.

is a maintenance release done right. It doesn't reinvent the wheel, but it makes the wheel spin smoother. For 48V builders using JBD hardware, this is the new baseline.

Its main capabilities typically include:

: Typically uses Bluetooth for one-to-one connections without needing an account.
