- Improved Victron Communications: This update refines the handling of high voltage alarms in the V2 model to ensure accurate performance. Improved communication enhances the monitoring and control of the battery system for greater reliability.
- Improved Scalability: Parallel Capability: The system can now handle up to 16 batteries in parallel, compared to the previous limitation of just 4. This greatly expands the potential for energy storage, allowing for larger systems.
- Upgraded Internal Components: Certified Components: The internal fuse is UL60691 certified, and the battery cells meet a range of safety and quality standards, including UL1642, UL1973, U9540A, IEC 62619:2017, and RoHS. This indicates that the battery is built to high safety standards and is suitable for various applications.
- Battery UL Listing: The battery is in the process of receiving its UL Listing (a certification for safety and quality). This will further confirm its compliance with industry standards.
- Improved Bluetooth App Compatibility: All-Battery Dashboard: The app now supports connecting to and monitoring all batteries from a single dashboard, even if you have up to 16 batteries in your system. This makes it easier to manage large-scale installations.
- BMS Over-the-Air Firmware Updates: The system can now receive firmware updates remotely via the app. This ensures the battery management system (BMS) is always running the latest software, which can improve performance, security, and features over time.
- Upgraded Battery Gauge: Better Monitoring: The new battery gauge provides more detailed information, including State of Charge (SOC), voltage, current flow, and alarm alerts. This is a significant improvement over the older version, which only had a 10-segment gauge. The added details help with better monitoring of the system's health and performance.

Recommended Charge Settings
To properly charge your Epoch Batteries, you will want to verify that any charging component in your system is capable of being programmed for the following specifications. Charging components can include, but are not limited to converters, inverter chargers, solar charge controllers, DC to DC chargers, etc.
- Bulk/Absorption: 14.2V – 14.6V
- Absorption Time: Two batteries in parallel connections require 30 minutes 200Ah
- Float: 13.4V – 13.8V
- Equalization: 14.4V/ Disabled
- Temperature Compensation: 0/Disabled
- Charge Rate: 50% of the battery or battery bank capacity
- Battery Charge Temperature Range: 32°F (0°C) to 131°F (55°C)
- Battery Discharge Temperature Range: -4°F (-20°C) to 140°F (60°C)
- Cell Charge Temperature: 32°F (0°C) to 131°F (55°C)
NOTE: Not all chargers are capable of multistage charging. If yours is not, you will want to verify it can be programmed for the Bulk/Absorption voltage and have the other items mentioned disabled if applicable. Consult your charger's manual or the manufacturer.

Frequently Asked Questions
if your charger puts out 14.4 to 14.6v at constant current and has a manual setting for AGM like the Minnkota 440pc and 460pc you can use it for lithium
All outboards with an alternator and most any outboard 2001 and newer are fine to use a lithium starter battery.
