Description
Overview
The Renogy 12V 100Ah Pro is built around a double active safety system. An automotive-grade BMS provides over 60 protections and alerts, and a second active backup protection cuts the circuit 40 times faster than passive protection if a MOSFET switch fails.
It heats itself automatically when the charging current is above 4A, so it can charge safely below freezing, and its UL94 V-0 casing resists fire. Bluetooth lets you check it from your phone.
Who it’s for
- Winter campers and ice fishermen who need power below freezing.
- Off-grid homes and RVs in hot climates.
- Anyone who wants the most protective battery Renogy makes in this size.
Key benefits
- 60+ BMS protections: an automotive-grade battery management system with over 60 protection mechanisms and alerts.
- Active backup protection: cuts the circuit 40 times faster than conventional passive protection if a MOSFET switch fails.
- Fire-resistant casing: rated UL94 V-0 for resistance to vertical burning.
- Self-heating: turns on automatically with a charging current above 4A for safe sub-zero charging.
- Bluetooth: monitor the battery from your phone.

FAQ
How does the self-heating work?
It heats automatically when the charging current is greater than 4A, so it can charge safely in sub-zero temperatures.
What is active backup protection?
A second safety layer that cuts the circuit 40 times faster than conventional passive protection if a MOSFET switch fails.
Warranty
Manufacturer’s warranty: 7 years, prorated. Prorated: replacements in the first 12 months are free; after that Renogy charges a share of the original price based on the time used. Solar panels, chargers and other items included in a bundle are covered by their own manufacturer’s warranty. Source: Renogy limited warranty.
