The Epoch 12100-ECO stores 1.28kWh in a Group 24 LiFePO4 case. Its 12.8V nominal voltage and 100Ah capacity make it a candidate for compatible RV, marine, solar and backup battery systems. Compare its 100A continuous-discharge limit with the DC current your inverter and other loads require.

This Eco Series model has low-temperature charge protection, but Epoch does not list Bluetooth or self-heating for SKU 12100-ECO. Its IP54 case resists limited dust ingress and splashes; it is not waterproof or submersible. Check the Group 24 dimensions, M8 terminals and charging profile before replacing a lead-acid battery.

  • Core configuration: 12.8V nominal, 100Ah, 1.28kWh, Group 24 LiFePO4
  • Best-use applications: compatible RV, marine, solar and backup battery systems
  • SKU: 12100-ECO

Epoch permits up to four matching batteries in series and up to 16 in parallel under its installation rules. Expansion requires matched batteries, correct wiring and protection. The battery carries a 6-year manufacturer warranty and is rated for 4,500+ cycles under Epoch’s stated test conditions.

Choose this Group 24 battery by its limits

The 12100-ECO supplies 12.8V nominal and 1.28kWh nameplate energy in a 21 lb Group 24 case. Its 100A continuous BMS discharge limit matters when sizing an inverter; compare DC current at low battery voltage, not only the inverter’s AC wattage. Charging must stay within the published 100A maximum and the allowed temperature range.

No built-in heating or Bluetooth. For those features, compare the Epoch 12105A-H heated Bluetooth battery. For more capacity without those features, compare the Epoch 12314-ECO. Check the exact model’s terminal, charger, and series/parallel rules before installation.

Frequently Asked Questions

Clear answers to common questions about this product, setup, compatibility, and use.

What are the core ratings of the Epoch 12100-ECO? This model is listed at 12.8V, 100Ah @ 0.2C, 1.28kWh. Actual usable energy and runtime depend on BMS limits, temperature, discharge rate, system settings, and the reserve maintained by connected equipment. Which features are included on this exact Epoch battery? This exact listing does not identify Bluetooth or heating in its product name. Choose those features only when they are explicitly listed for the model. What charger should I use with the Epoch 12100-ECO? Use a charger with the correct battery chemistry, nominal voltage, charge profile, and current for this exact battery. The BMS limit, cable size, fuse protection, and lowest charging temperature must also be respected. Can this battery be connected in series or parallel? Only use the series and parallel configurations explicitly permitted in the current Epoch manual for this exact model. Match model, capacity, age, firmware, state of charge, cabling, and protection before combining batteries. Will this battery work with any inverter or vehicle? No. Verify nominal voltage, continuous and surge current, communication requirements, physical fit, charging source, cranking requirements, and terminal configuration for the complete installation. What service life and warranty should I expect? Epoch lists 4,500+ cycles. The listed warranty is 6-year manufacturer warranty. Actual life depends on temperature, depth of discharge, current, charging, storage, and correct installation.
