The Epoch Essential Series 12V 105Ah LiFePO4 battery gives RV, marine, van, solar, and off-grid users a compact drop-in replacement for heavy lead-acid or AGM batteries. With a Group 24 footprint, 22.1 lb weight, and 1.34kWh of stored energy, it delivers dependable lithium runtime without taking up extra space.
Unlike many bare-bones budget batteries, this model includes the premium essentials customers actually want: internal heating for cold weather charging, a Bluetooth battery monitor through the Epoch battery app, and smart BMS protection for safer everyday use.
True Drop-In Group 24 Size
The compact 10.25 in × 6.75 in × 9.00 in footprint is designed for Group 24 battery trays, marine battery boxes, and RV battery compartments. Always verify tray fitment, cable clearance, hold-down strap location, and terminal access before installation.
Lightweight Power
At only 22.1 lbs, this lightweight lithium battery can remove significant weight compared with traditional lead-acid options, helping improve RV payload efficiency, boat handling, and overall system serviceability.
Premium Tech Built into our Essentials Package
Internal heating, Bluetooth monitoring, and smart BMS protection separate it from basic budget batteries.
Smart Internal Heating for Cold-Weather Charging
Standard lithium batteries can be damaged if charged below freezing. The internal heating feature helps protect your investment by warming the cells before accepting normal charge current, supporting safer cold weather charging during winter camping, early-season boating, and off-grid use.
Built-In Bluetooth & Free Epoch Monitoring App
Skip complicated external shunts for basic battery visibility. The built-in Bluetooth battery monitor connects directly to the Epoch battery app so you can view state of charge, voltage, current draw, temperature, and battery status from your phone.
105Ah Capacity: More Power Than the Standard 100Ah
That extra 5Ah provides a true 1.34kWh lithium battery capacity, giving you more runtime for trolling motors, CPAP machines, RV electronics, lights, pumps, refrigerators, and off-grid loads in the same compact Group 24 size class.
Expandable Power for Any Application

Why upgrade to Epoch LiFePO4?
More usable energy. Less maintenance. Smarter battery visibility.
LiFePO4 technology provides stable voltage output, long cycle life, fast charging capability, and maintenance-free operation. Compared with lead-acid batteries, this Epoch Essentials battery delivers more usable energy in a lighter package while adding Bluetooth monitoring, internal heating, and smart BMS protection.
Fitment and charging note
Verify your tray, wiring, charger, and system design before installation.
Always confirm Group 24 tray dimensions, terminal access, cable clearance, charger compatibility, overcurrent protection, and system requirements before installation. Use a LiFePO4-compatible charger, RV converter, solar charge controller, inverter charger, or DC-to-DC charger programmed within Epoch’s recommended charging parameters.
12V 105Ah Heated Bluetooth LiFePO4 Battery FAQs
Answers for Group 24 fitment, Bluetooth monitoring, cold-weather charging, expansion, and charger compatibility.
Is this battery a direct replacement for my standard 12V RV or boat battery?
Yes. The Epoch 12V 105Ah Essentials battery is designed as a Group 24 drop-in replacement for many standard 12V RV and marine battery trays. It fits the common Group 24 footprint while offering far less weight and more usable energy than many lead-acid or AGM batteries. Always verify tray dimensions, cable clearance, terminal orientation, and charger compatibility before installation.
Do I need to buy a separate battery monitor or shunt?
No external monitor is required for basic battery visibility. This 12V Bluetooth lithium battery includes a built-in Bluetooth module that communicates with the Epoch battery app, allowing you to view state of charge, voltage, current draw, internal temperature, and battery status from a compatible iOS or Android device.
How does the internal heating feature work?
Charging lithium batteries below freezing can damage the cells. The built-in internal heating system helps protect the battery by using incoming charge power to warm the cells before normal charging begins. This supports safer cold weather charging for winter camping, early-season boating, and off-grid storage situations.
Can I wire these batteries together to make a 24V or 36V trolling motor system?
Yes. The Epoch 12V 105Ah Essentials battery can be wired in series up to 4 batteries to create 24V, 36V, or 48V systems. It can also be wired in parallel up to 4 batteries to increase total amp-hour capacity. Use matched batteries of the same model, age, capacity, and state of charge, and follow Epoch installation guidance.
Why choose a 105Ah battery instead of the industry-standard 100Ah?
Epoch packs 105Ah into the Group 24 size class, giving you 1.34kWh of usable energy in a compact footprint. That extra 5Ah can provide additional runtime for trolling motors, RV electronics, lighting, refrigeration, CPAP machines, pumps, and other 12V loads without taking up more physical battery space.
Can I charge this with my existing alternator or standard battery charger?
For best performance and lifespan, use a charger, RV converter, solar charge controller, or inverter charger with a dedicated LiFePO4 charge profile. Epoch lists 14.2V–14.4V bulk/absorption, float disabled preferred or 13.3V–13.6V, and equalization disabled. For alternator charging, a DC-to-DC charger is highly recommended to protect both the alternator and battery.
Is this battery heated and Bluetooth enabled?
Yes. This model includes both internal heating for cold-weather charging support and Bluetooth app monitoring. These are the key premium features that separate it from many lower-cost bare-bones 12V 100Ah deep cycle replacement batteries.
Is this battery waterproof?
This model is IP54 rated, meaning it is dust protected and splash resistant for protected RV, marine, van, and mobile power compartments. It is not designed for submersion or locations where standing water can collect around the battery.

Wonderful upgrade
Working duration is amazing compared to similar Ah lead acid. Lightweight, BMS info and built in Bluetooth super easy. Very happy so far
Lithium Battery Review
I've only had the 3 lithium batteries in service for a couple of weeks. So far they have performed beyond my expectations. Lasting way longer than the lead acid batteries that were in the boat.
Outstanding batteries
I bought 2 of these 105s for my sailboat house bank and just added another to boost capacity. They are great batteries. Customer service is also top notch. Thanks, Epoch!
