The Epoch 12V 300Ah Essential Series LiFePO4 battery (SKU: 12300A-H) was built to fix all three problems in a single Group 31 package that fits where your old battery already lives.\u003c\/p\u003e\n\u003cp\u003eOwners switching from paired lead-acid or AGM banks report dropping 100 to 400 lbs of battery weight while gaining two to three times more usable capacity in the same compartment, on the same cable runs, without rebuilding the battery bay. Sailors have run overnight at anchor on electronics, refrigeration, and cabin lighting without touching the generator. Anglers have trolled for over four hours using less than 15 percent of a two-battery parallel bank. RV owners have run an inverter, a 12V refrigerator, and an air conditioner for three consecutive days and still had charge remaining.\u003c\/p\u003e\n\u003cdiv class=\"ep-highlight\"\u003eOne 12300A-H weighs 58 lbs and delivers 300Ah of fully usable capacity. Two paired Group 31 lead-acid batteries delivering the same usable capacity weigh over 200 lbs and require regular maintenance. The Group 31 form factor means it drops into the space your old battery already occupies on most vessels and vehicles.\u003c\/div\u003e\n\u003cspan class=\"ep-section-head\"\u003eBuilt-in self-heating for cold-water operation\u003c\/span\u003e\n\u003cp\u003eStandard lithium batteries cannot be safely charged below freezing. The 12300A-H solves this with an internal heating element that activates automatically through the BMS the moment temperatures drop below the safe charging threshold. Charging is enabled down to -4 degrees Fahrenheit (-20 degrees Celsius) with heating active making this battery suitable for year-round operation in northern climates, cold-weather fishing seasons, and early-spring boating where overnight temperatures frequently fall below freezing. The heater draws its power from incoming charge current, not from the battery itself, so it does not drain the pack while connected to solar or shore power.\u003c\/p\u003e\n\u003cspan class=\"ep-section-head\"\u003eBluetooth monitoring with security PIN\u003c\/span\u003e\n\u003cp\u003eThe battery connects to the free Epoch Li-Ion App on iOS and Android via Bluetooth. The app displays real-time state of charge, cell-level voltages, current amps in and out, temperature readings, and a battery event history log. A unique security PIN is printed on the top of each battery and is required on first connection this prevents anyone nearby from connecting to your battery, reading its data, or changing its configuration. The PIN is permanent and cannot be changed. Photograph it when you install the battery and keep it somewhere accessible.\u003c\/p\u003e\n\u003cp\u003eWhen two or more batteries are connected in parallel, the app detects the bank configuration automatically and displays all units together. Owners running parallel banks report checking state of charge from inside the cabin or the cockpit without ever opening a hatch and without needing a separate external shunt.\u003c\/p\u003e\n\u003cspan class=\"ep-section-head\"\u003eEVE prismatic cell construction\u003c\/span\u003e\n\u003cp\u003eThe 12300A-H is built using EVE prismatic LiFePO4 cells. Epoch Batteries has a direct, long-established supply relationship with EVE and has been involved in selecting every component cells, BMS, and heating elements since the product was first designed. Most battery brands in this segment do not disclose which cells are inside their products or which grade of cells is used. Epoch publishes this information because it matters to informed buyers.\u003c\/p\u003e\n\u003cspan class=\"ep-section-head\"\u003eScalable for larger systems\u003c\/span\u003e\n\u003cp\u003eConnect up to four batteries in series for a 48V system or up to four in parallel for a 1,200Ah bank at 12V.

The battery base measures 13.75 inches long and 7.63 inches wide, with a height of 10.00 inches (10.50 inches with bolt terminals). These dimensions fit the standard Group 31 footprint used in the majority of marine battery boxes and RV battery compartments. Verified installations include Winnebago View, Winnebago Solis, Airstream 27 GT, Thor Sequence, Coachmen Leprechaun, Jeanneau 36.2, Hallberg-Rassy sailboats, trawlers, and numerous travel trailers and 5th wheels. Some installations required trimming the plastic handles or sourcing slightly longer cable leads. Measure your compartment before ordering and compare against the specifications listed in the Tech Specs tab.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq2\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq2\" class=\"faq-label\"\u003eHow does the Bluetooth security PIN work?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eEach battery ships with a unique security PIN printed on the top of the battery case. When connecting to the Epoch Li-Ion App for the first time, you will be prompted to enter this PIN. Once entered, the connection is established and the battery is protected against unauthorized Bluetooth access. The PIN prevents other people from connecting to your battery, monitoring it, or altering its configuration settings. The PIN is permanent and cannot be changed or deleted. Photograph the PIN when you install the battery and keep it somewhere accessible for future reference.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq3\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq3\" class=\"faq-label\"\u003eWhat does the Bluetooth app show and does it replace a shunt?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eThe free Epoch Li-Ion App (iOS and Android) displays real-time state of charge as a percentage, individual cell voltages, total pack voltage, current amps flowing in and out, battery temperature, and a log of BMS events. When two or more batteries are connected in parallel, the app detects the configuration and displays them together as a bank. Many customers find the app provides sufficient monitoring without a dedicated external shunt. For customers running a full Victron system with a Cerbo GX, a SmartShunt is recommended alongside the app for whole-system visibility.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq4\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq4\" class=\"faq-label\"\u003eCan I charge this battery in freezing temperatures?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eYes. The built-in self-heating element enables charging at temperatures as low as -4 degrees Fahrenheit (-20 degrees Celsius). The heater activates automatically through the BMS when the battery temperature drops below the safe charging threshold. The heater draws approximately 10 to 11 amps from the incoming charge current solar, shore power, or an alternator-connected DC-DC charger must be connected for the heater to operate. The battery does not discharge itself to generate heat. Discharge is also rated to -20 degrees Celsius. Optimal discharge performance occurs between 59 and 95 degrees Fahrenheit (15 to 35 degrees Celsius).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq5\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq5\" class=\"faq-label\"\u003eCan I store this battery in an unheated space over winter?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eThis is an important limitation to understand before purchasing. The self-heating element in this battery cannot be disabled. If the battery is stored in a location where temperatures drop below freezing and it is not connected to a charge source, the heater will activate automatically and draw power from the battery until it discharges completely. For cold-weather storage without a charge connection, three options are recommended:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConnect the battery to a trickle charge source such as a solar panel or shore power to keep it topped up\u003c\/li\u003e\n\u003cli\u003eRemove the battery from the vessel or vehicle and store it indoors at 50 to 100 percent state of charge\u003c\/li\u003e\n\u003cli\u003eIf leaving it in place, charge it fully before winter and recharge every three months as recommended by the manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eStorage temperature range is 32 to 95 degrees Fahrenheit (0 to 35 degrees Celsius).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq6\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq6\" class=\"faq-label\"\u003eIs this battery compatible with Victron MPPT, MultiPlus, or Cerbo GX?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eYes, this battery works with Victron MPPT solar charge controllers, MultiPlus and Quattro inverter\/chargers, Orion DC-DC chargers, SmartShunt, and Cerbo GX using standard LiFePO4 charge parameters. Set the charger to LiFePO4 mode with 14.4V Bulk and Absorption, 13.8V Float, and disable equalization and temperature compensation. The 12300A-H Essential Series does not include Victron CANBUS communication. This means the battery does not communicate directly with the Cerbo GX to report state of charge or charge limits. A Victron SmartShunt provides system-level monitoring alongside the Epoch app for Essential Series installations.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq7\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq7\" class=\"faq-label\"\u003eWhat size inverter can I run from a single 300Ah battery?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eThe 12300A-H has a 200A continuous BMS, which limits practical continuous output to approximately 2,560 watts at 12.8 volts. A 2,000-watt pure sine wave inverter pairs well with a single battery for most marine and RV loads including refrigeration, lighting, phone and device charging, CPAP machines, and small kitchen appliances. For a 3,000-watt inverter, two batteries in parallel are recommended to stay within BMS current limits under sustained load. For high-draw appliances such as air conditioners or microwave ovens, plan for two or more batteries in parallel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq8\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq8\" class=\"faq-label\"\u003eCan I connect two or more of these batteries in parallel?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eYes. Up to four batteries can be connected in parallel for a 1,200Ah bank at 12V. Before connecting batteries in parallel, charge each battery individually to the same state of charge to minimize inrush current between units. Use equal-length cables from each battery to a common bus bar to ensure balanced current sharing. It is not recommended to parallel batteries of significantly different ages or cycle counts, as differences in internal resistance can cause unequal load distribution. Using batteries of the same model and similar charge history produces the most consistent parallel performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cinput id=\"faq9\" type=\"checkbox\"\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003clabel for=\"faq9\" class=\"faq-label\"\u003eDoes my existing boat charger or RV converter need to be replaced?\u003c\/label\u003e\n\u003cdiv class=\"faq-body\"\u003e\n\u003cp\u003eOnly if your current charger does not support LiFePO4 voltage parameters. Many older RV converters charge to 13.6V or lower designed for lead-acid or AGM and will undercharge a LiFePO4 battery over time. Marine chargers vary by manufacturer and model. Check that your charger can be set to 14.4V Absorption and 13.8V Float with equalization disabled. If not, options include replacing the charger with a lithium-compatible unit, installing a compatible upgrade board for your existing converter, or adding a dedicated DC-DC charger for the lithium bank.
