Product Summary
The Epoch Essentials 24V 230Ah puts 5.89kWh of LiFePO4 in a Group 8D case just 8.6 inches tall, so a full 24V house bank fits low battery boxes and under-bunk compartments. With 200A continuous, self-heating and Bluetooth monitoring, it replaces the two 12V batteries a 24V RV, boat or cabin usually runs in series.
Specifications:
- 25.6V nominal, 230Ah and 5.89kWh (5,888Wh) from eight prismatic LiFePO4 cells in series (8S1P)
- 200A continuous discharge and charge, with 300A peak discharge for up to 10 seconds
- Self-heating charges from -4°F to 131°F (-20°C to 55°C), powered by the charger, never by stored energy
- Bluetooth monitoring of state of charge, voltage, current and temperature in the Epoch Li-Ion app (iOS and Android)
- BCI Group 8D case, 8.60 in high, 20.55 in long and 9.45 in wide (218 × 522 × 240 mm), 84 lb (38.1 kg)
- M8 female terminals in an IP54 dust-protected, splash-resistant case
- Parallel expansion at 24V, with Epoch planning examples up to four batteries (920Ah)
- 4,000+ cycle rating and an 11-year limited warranty

About the Epoch Essentials 24V 230Ah Battery
A 24V bank usually starts as two 12V batteries in series. That's two cases, a jumper cable and four terminals to keep tight. The Essentials 24V 230Ah does the same job in one case, with 5.89kWh behind a single pair of M8 terminals. At 8.6 inches tall in a Group 8D footprint, it drops into low battery boxes, under-bunk bays and cabin battery shelves.
It also has the most continuous current in Epoch's 24V 230Ah lineup: 200A continuous, about 5,120W at nominal voltage. When a compressor, well pump or welder kicks on, it handles 300A for up to 10 seconds. That headroom lets one battery feed a 24V inverter-charger like the Victron MultiPlus-II 24V 3kVA, as long as its continuous DC draw stays inside 200A.
Essentials vs V2 Elite vs V2-T Elite: Choosing an Epoch 24V 230Ah Battery
All three store 5.89kWh at 25.6V nominal, so the choice comes down to fit, communication and protection. The Essentials is the low-profile, high-current option. It's 8.6 inches tall against 12.06 inches for the Elite models, and at least 13 lb lighter. It's rated 200A continuous, where the V2 Elite carries 110A and the V2-T 115A. It reports over Bluetooth, has an IP54 rating for dust and splashes, and builds 24V banks in parallel.
The V2 Elite adds CAN bus communication with a Victron GX device, so the battery sets its own charge limits. It also adds an IP67 case, banks of up to 16 in parallel or two in series for 48V, and an included gauge and remote switch. The V2-T Elite builds on the V2 with a user-serviceable 300A Class T fuse inside the battery. Both Elite models give free repair or replacement for the first five years of their 11-year warranty. The Essentials includes free replacement in years 1 to 3.
Self-Heating for Cold-Weather Charging Down to -4°F
The Essentials handles cold charging on its own. When the cells reach 32°F (0°C), the BMS pauses charging and an internal heater warms them with power from your charger. Charging picks back up on its own at 41°F (5°C). The heater wakes whenever a charger supplies at least 0.5A. It runs only on that incoming current, so a battery parked in a cold RV or cabin keeps its stored energy for your loads. The heating system is tested to -4°F (-20°C).
Bluetooth Monitoring and Victron GX Visibility With a SmartShunt
The Epoch Li-Ion app shows state of charge, voltage, current, temperature and status on your phone. The battery's built-in shunt does the measuring, with 0.2A accuracy on discharge. The Essentials talks over Bluetooth only. On a Victron system, a Victron SmartShunt puts the bank's state of charge and current on your GX dashboard, next to solar and inverter data.
Installing a 24V Group 8D Lithium Battery: Fusing, Cables and Mounting
Epoch sizes everything around the continuous rating: loads, wiring and overcurrent protection to 200A. The 300A peak is a 10-second allowance. Put the main fuse or DC-rated breaker as close as practical to the positive terminal. A Class-T fuse in a Blue Sea Systems Class-T fuse block is the main protection a lithium bank this size calls for, rated to interrupt 20kA.
Run equal-length, equal-gauge cables to every battery in a parallel bank. Our custom battery and inverter cables are made to order from 6 AWG to 4/0 AWG, so matched runs come out identical. Torque the M8 terminals to 71 to 106 in-lb (8 to 12 N·m).
Install the battery upright on a tray, strap or bracket rated for its 84 lb. Epoch lists its Epoch battery tray for the 12460A-H and 24230A-H as a fit for this model. Before you join batteries in parallel, charge each one full and bring them all to the same state of charge. Epoch approves this model for parallel banks only.

Frequently Asked Questions
Use a LiFePO4 profile with bulk/absorption at 28.4 to 28.8V. End it when charge current falls to 11.5A or after 15 minutes, whichever comes first. Turn float off (Epoch's preference) or set it to 26.6 to 27.2V. Set re-bulk to 26.4V, and turn off equalization and temperature compensation.
Epoch recommends 115A of charge current, with 200A as the continuous maximum. Program every charge source the same way, including solar charge controllers, inverter-chargers, converters and DC-DC chargers.
No. Epoch approves this model for parallel banks only, so it stays a 24V battery. For a 48V-class bank built from 24V batteries, look at the V2 Elite and V2-T Elite 24V 230Ah models. Each one allows two in series (51.2V nominal).
Yes, through a DC-DC charger. Epoch highly recommends one to protect both the alternator and the battery. Program it with the same LiFePO4 settings as your other chargers. If your vehicle has a 12V alternator, pick a DC-DC charger with a 12V input and 24V output.
Mount it above bilge water, in a compartment that stays mostly dry. The IP54 case handles dust and splashes. Epoch's warranty excludes damage from submersion and pressure washing, so keep hoses and standing water away from it.
Epoch plans on about 4,710Wh of usable energy per battery (80 percent of nominal). That's a conservative planning figure, not a rating. Divide it by your average load and allow for inverter losses. A steady 500W load runs about 9.4 hours before losses, and a 1,000W load about 4.7 hours.
Store it clean and dry at about 50 percent charge or higher, ideally between 32°F and 95°F (0°C to 35°C). Check the charge at least every 3 months. Epoch's warranty excludes batteries left uncharged for more than three months. It also excludes storage above 140°F (60°C) or below -40°F (-40°C).
