Fogstar Drift:
High-Power Installation
A technical guide to installing Fogstar Drift batteries with Victron MultiPlus-II inverters for high-demand UK van builds.
Installation Overview
Installing a 280Ah or 300Ah Fogstar Drift battery is more than just swapping a leisure battery. These units can deliver huge amounts of current (up to 200A continuous on the PRO models), which requires a complete rethink of your DC distribution and fusing strategy.
High Current Warning
At 200A, even a small amount of resistance in a loose connection can generate enough heat to melt cable insulation or start a fire. Every high-power connection must be crimped with hydraulic tools and torqued to manufacturer specifications.

Fusing & Protection
We recommend the **Victron Lynx Distributor** for all Fogstar installations. It provides a central, fused busbar for the high-power DC lines. For a 3000VA inverter, a **400A Mega Fuse** is required on the positive line to handle the massive surge currents during startup.
Cable Selection (UK Standards)
Do not use standard automotive cable for these runs. Use **BS 6231 (Tri-Rated)** flexible panel wire. For a MultiPlus 3000, **70mm²** is the minimum cable size for short runs, but **95mm²** is preferred if the battery is more than 1.5m from the inverter.
BMS Configuration
Before connecting your battery to the system, download the Fogstar Drift App. Ensure the BMS is updated to the latest firmware and check that the heating function is enabled. This is crucial for UK winter touring.
