Buying Guide

Match amperage to your RV

Confirm whether your RV uses 30A or 50A service and choose surge protectors or monitors rated for that amperage to avoid mismatches

Prioritize surge and EMS features

Look for combination surge protection and electrical management system (EMS) features to defend against miswired pedestals, voltage spikes, and neutral issues

Check battery chemistry and BMS

When selecting a lithium option, verify it includes a built-in battery management system (BMS) that supports overcurrent, overvoltage and temperature protection

Use battery monitors with shunts

Choose battery monitors that include or support a shunt for accurate state-of-charge, current flow, and runtime estimates for lead-acid or LiFePO4 systems

Balance portability and permanence

Portable protectors are ideal for campsite use and transfer between rigs, while hardwired or heavy-duty units suit long-term installations
