Safely test dangerous scenarios in our simulator.
This simulator shows why battery type, charge profile, temperature, BMS and critical loads must be designed as one system. The goal is simple: VHF, navigation lights, bilge pump and navigation must never lose power when you need them.
Use the scenarios first. They show common faults and safe principles without requiring the user to understand every battery parameter.
Choose a scenario and start the simulation. The goal is to show what happens to the power supply and critical functions.
A good installation is not just about battery capacity. It is about what happens when something goes wrong: cell voltage too high, cell voltage too low, charging when too cold, the wrong charge profile, or a BMS disconnect.
On a leisure boat the battery is not just comfort. It can supply VHF, navigation lights, bilge pump, navigation, autopilot and other safety-critical equipment. Poor system design can therefore have consequences far beyond low voltage.
A LiFePO4 battery with an internal BMS can disconnect charging or discharge on overtemperature, undertemperature, over-/undervoltage or cell imbalance. If every load sits behind the same disconnect, critical circuits can lose power at once.
Lead-based batteries react differently from lithium. The wrong charge profile, high temperature or overcharging can cause gassing, pressure build-up in VRLA batteries, venting and permanent loss of capacity.
Get the battery, charging, BMS, critical loads, cable sizing, protection and system architecture assessed before the fault happens at sea.
Bulk: Maximum current. Absorption: Constant voltage topping. Float: Maintenance.
SOC: State of Charge (0-100%). SOH: State of Health (Degradation).
Communication between battery and charger. Prevents BMS emergency shutdowns.
The rate of charge/discharge relative to capacity. 1C on 100Ah = 100A.
Lithium Iron Phosphate is thermally stable and does not catch fire if punctured or overcharged.
Describes how a lead-acid battery's capacity decreases the faster it is discharged.
