48V 100Ah V2-T Elite Series LiFePO4 Battery (5.12kWh)
This is a special order item, please allow up to 2 weeks for delivery. If the battery is out of stock, we will contact you with lead times and options.
- 48V 100Ah V2-T Elite Series LiFePO4 Battery (5.12kWh): 51.2V nominal, 100Ah and 5,120Wh (5.12kWh) of nominal stored energy in one case, for native 48V off-grid solar, marine, RV and backup power systems; plan runtime on about 4,096Wh. A deep-cycle battery for house power and energy storage, not engine starting.
- User-Serviceable 250A Class T Fuse: A 250A Eaton Class T fuse behind a sealed top service panel improves source protection at the battery. It does not replace the main disconnect, downstream protection or cable sizing: install a DC-rated fuse or circuit breaker in the positive conductor, as close to the battery as practical.
- Native VICTRON Communications: CAN bus at 500 kbit/s to a compatible Victron GX device (Cerbo GX, Ekrano GX or Cerbo GX Mk2). The battery reports its status, and with DVCC on it sets the charge voltage and current limits of Victron chargers. The communication harness is included; set the DIP switches and GX settings per the manual.
- Elite Performance Specifications: 80A maximum continuous discharge, about 4,096W DC at 51.2V before inverter losses, and 250A for 10 seconds for surges. 80A maximum continuous charge from all sources combined, with up to 90A for 5 seconds. If an inverter's continuous DC input can exceed 80A, add batteries in parallel.
- BLUETOOTH Monitoring: Bluetooth through the included battery gauge, which shows state of charge, voltage and current. The free Epoch Cloud app (iOS and Android) shows state of charge, voltage, current, temperature, cycles and alerts for each battery and the bank. A mountable external power button is included.
- HEATED For Cold Climates: LiFePO4 cells must not be charged below 0°C (32°F). When the battery is too cold to accept charge, the BMS uses incoming charge current to power the internal heating pads first, then allows normal charging once the cells reach a safe temperature. Charging is supported down to -30°C (-22°F) ambient when charge current is available; discharge works down to -20°C (-4°F).
- IP67 Rated Enclosure: Dust-tight and protected against temporary immersion in up to 1m of water for 30 minutes, with all seals and glands installed. It is not rated for water jets, pressure washing or continuous submersion: install it where it stays dry in normal use, with all harness connectors fully seated.
- Dimensions & Fit: 20.86" L x 8.65" W x 12.06" H (529.8 x 219.8 x 306.3 mm; the height includes the terminal posts), 97 lb (approx. 44 kg). Lift with two people and install it upright. Replacing a Group 8D lead-acid battery? Confirm tray fit, hold-down and lid clearance first; the optional Epoch V2 & V2-T mounting bracket (8D, sold separately) fastens to the threaded inserts on the case.
- Parallel Banks Only: Up to 16 batteries in parallel (1,600Ah, 81.92kWh), using matched C48100A-A batteries of the same age, capacity and state of charge, with the DIP switches set for the bank. The C48100A-A is a native 48V battery: do not connect it in series; series-parallel is not supported either.
- Advanced Smart BMS & Certified Components: Overcharge, over-discharge, over-current, short-circuit and high/low temperature protection. UL 1642, UL 9540A and IEC 62619:2022 cells; UL 60691 internal fuse; UN 38.3 (transport).
- 3,500+ Cycle Life & 11-Year Limited Warranty: Rated for 3,500+ cycles (to 70% capacity). Maintenance-free: no watering or equalizing, though regular inspection and 12 N·m terminal torque checks keep the system safe. Backed by an 11-year limited warranty (5 years of free repair or replacement, then 40% off MSRP on a replacement battery through Year 11); register within 90 days or keep your proof of purchase.

FAQs
What do I do with my Lithium batteries when the weather is cold?
Cold Weather Maintenance
- You can discharge (take energy out) of the batteries down to a battery core temperature of -4 degrees F.
- You can recharge lithium batteries when the core temp of the battery is 32 degrees F or warmer (41 degrees or warmer for Victron batteries. Victron is listed in C, this is 5 Degrees C)
- If your batteries have heaters, do not leave the heaters on all night unless you are plugged into shore power, as you will use unneeded energy.
- If your batteries have heaters, but there is no way to charge (not plugged into shore power, no generator available, solar panels are covered in snow), turn your heaters off.
- If you do not have heaters, your batteries MUST be warmer then 32 degrees F to charge (41 degrees for Victron).
- Some battery heater installations do not feature a switch for remote operation. If that is the case, your heaters will turn on and off automatically as temperatures demand. Please keep an eye on your battery state of charge.
- If you are not using your trailer / RV etc. for the winter, ensure your batteries are above 80% state of charge, and disconnect the master Negative cable from the batteries. If you have Battle Born heated batteries (BB12100H) disconnect the “heat enabled” wire from the small red button terminal located right beside the positive terminal.
- Many customers have main disconnect switches that will cut the power to the batteries, but you should take extra care that they are TRULY disconnected. Often RVs will still have a C02 sensor, backlit stereo, or some other emergency sensor that is bypassing this switch. If you are in doubt, simply disconnect the main positive and negative wires that supply your batteries. After the winter storage time, you should have plenty of charge in the batteries.
- With LiFePO4 batteries, we recommend disconnecting all potential power draws from the battery and letting them sit with a full charge, or at least a 50% charge minimum. On a full charge, LiFePO4 batteries have been proven to last at least a year in proper storage conditions with a 2–3% depletion each month. If left at a half charge, the batteries have the potential to not last as long in storage.
- Tests indicate that at 0 degrees Fahrenheit, with no insulation, the Battle Born internal heater is on about 30% of the time. With no external charging or loads, it gives approximately 185 hours (7 days) of heat capability before the battery goes into a low voltage disconnect.
- If the batteries are stored without a charge, their levels could dip below what the internal Battery Management System, or BMS, can protect over the winter season. If possible, we recommend storing them fully charged in an environment above freezing. Our team recommends not leaving a completely drained battery in that state for an extended amount of time, as it can damage the cells inside. Doing so will void the warranty!
- If you do find yourself with batteries that are too cold to charge, you have a couple of options:
- Bring the batteries into a warm space or park your vehicle indoors
- Run a space heater (use caution) inside your vehicle to warm the batteries up. DO NOT use power from the batteries ie. Your inverter, to power the heater. Run an extension cord from your house to the vehicle and plug the heater into your home.
- If your batteries are above 60% state of charge, and you can confirm there is no load on the batteries (verify though your shunted meter, you should see 0.0A / 0W load), you can safely leave your batteries for 90 days without worry.
- LEAVING A LITHIUM BATTERY IN A FULLY DISCHARGED STATE WILL VOID YOUR WARRANTY!!!!
- When in doubt, remove your batteries and bring them into us to be fully charged and ready for storage. This will take 24-48 hours. TAKE PICTURES OF YOUR SYSTEM BEFORE DISCONNECTING ANY WIRING. We are not liable, nor can we assist with “I forgot where this wire goes”. That is your responsibility.
Can you install a kit/parts I already bought?
We do not install customer supplied parts or items purchased through our website. All items for your installation must be purchased through Bend Battery's retail location with guidance by a technician.
Do I need to bring my receipt with me if I have any questions?
All of our clients are saved into our computer system under their first and last name so you do not need to keep your receipt. If you for any reason have lost your receipt and would like another copy, please email us with the first and last name you used during purchase and we would be happy to email you a copy.
I am not sure how to use my VictronConnect App to monitor my system, what can I do?"
The VictronConnect App allows you to wirelessly monitor your system and recieve a wealth of information about your voltage, current, state of charge, load output, load current, solar production and much more. Below is a link to Victron Energy's Youtube channel as well as their manual on their website which gives you step by step instructions and explanations of each feature. Once you get the hang of the basic features, you will be amazed at how much information about your system is right at your fingertips. If you are still struggling, please email us at bendbattery@gmail.com for further assitance.
Are you open on the weekends?
We are open Monday-Friday 9AM-3PM for walk in customers. The rest of our day is dedicated to one-on-one appointments with clients. We reserve the weekend for our team to get out, enjoy life and recharge their own batteries so they can be ready to help you with all your questions when they return on Monday.
Do you fix cell phones, cameras and laptops?
We do not fix cell phones, cameras or laptops. Please look for a local repair shop that specializes in small electronics to assist you.
Do you sell or work on Golf Carts?
We do not sell golf carts. We exclusively sell Trojan and LifeLine batteries for drop in replacement batteries. We also make custom replacement cables made of USA made welding cable, a 16 ton 6 way hydraulic crimp press and double walled heat shrink for the ultimate connection and protection from the environment. We do not provide any other services or maintenance packages for golf carts.
