Frequently Asked Questions

How many charging banks do I need?

Match the number of charging banks to the number of separate battery banks you want to charge, such as a starting battery and a house bank. A multi-bank Guest charger keeps each bank topped independently. Also match the amp output to your bank size and chemistry.

What does a battery switch do?

A battery switch turns banks on and off and selects between them, controlling your power and isolating banks for safety and service. Match the switch to your bank configuration and the current it must carry, and choose the type that fits your setup.

Does the charger support my battery type?

Battery chemistries like lithium, AGM, and flooded need the correct charge profile, so confirm the charger supports your battery type before buying. Using the right profile charges safely and protects battery health. Check the product details for supported types.
