12V LiFePO4 Batteries – The Most Versatile Starting Point

A 12V LiFePO4 battery is the most common upgrade path from lead-acid – and for good reason. It's a direct replacement for Group 24, 27, and 31 batteries, which means you can swap one in without rewiring your boat, RV, or solar system. At roughly 25 lbs for a 100Ah unit (compared to 60–70 lbs for lead-acid), the weight savings alone change how a small boat handles or how much payload your RV carries.

Most of our 12V LiFePO4 batteries include Bluetooth monitoring and built-in heating for Canadian conditions. If your setup demands more than 12V, some models can be wired two in series for a 24V bank or four for 48V – but only where the manufacturer states the battery supports series connection, since not every BMS tolerates it. Purpose-built 24V and 48V batteries are usually the cleaner solution for larger systems anyway.

24V LiFePO4 Batteries

24V systems bridge the gap between 12V portability and 48V high-power. You'll find them in larger trolling motor setups (Minn Kota 24V), mid-size RV house banks, and commercial marine applications. You can build a 24V bank from two 12V batteries in series, or go with a purpose-built 24V unit for simpler wiring and integrated BMS protection.

Our most popular 24V options: the Epoch 24V 100Ah for mid-range setups, the Epoch 24V 230Ah Elite V2 for large-capacity systems with Victron communication, and the ReLiON RB24V100 for professional marine installations. See the full 24V battery range.

36V LiFePO4 Batteries

36V is trolling motor territory. Bow-mount motors above roughly 100 lbs of thrust run on 36V, which traditionally meant three lead-acid batteries in series, three sets of terminals to corrode and around 180 lbs sitting in the bow of a boat that would rather not carry it.

A single 36V LiFePO4 pack replaces all three. One battery, one set of connections, roughly a third of the weight, and because lithium holds voltage nearly flat through the discharge curve the motor pulls the same thrust at the end of the day as it did at launch. That last part is what anglers notice first. The Epoch 36V 100Ah with heating and Bluetooth is the pack most Ontario boats end up with. See the full 36V battery range.

48V LiFePO4 Batteries

48V is where the largest part of this collection sits, and where serious electric propulsion lives. Above roughly 3 kW almost every system is built on it, for one reason: at the same power a 48V bank draws a quarter of the current of a 12V one. Quarter the current means thinner cable, smaller fuses, less voltage drop across a long run and far less heat in the lockers.

The range spans dedicated propulsion packs and general house banks. RIM Drive and WaterWorld batteries are rated in watt-hours rather than amp-hours, so divide by the nominal 51.2 volts when you want to compare them against an Ah-rated pack. ePropulsion's E60 and E163 are matched to their own motors and communicate with them. The Epoch 48V 100Ah V2 Elite adds cell heating, Bluetooth and Victron communication, which matters if the boat or cabin already runs a Victron system.

A modular option is coming as well. The kMax 48V battery holds 1,024 Wh in an 11 kg portable pack with an IP67 rating, and up to four run in parallel for just over 4 kWh. It is built for kayak propulsion rather than fixed installation, and ePropulsion expects it in spring 2027. Browse everything at this voltage in the 48V battery collection.

Why LiFePO4 Is Replacing Lead-Acid

Lithium iron phosphate isn't new – it's been the chemistry of choice for marine, RV, and off-grid applications for over a decade. Here's what the numbers actually look like.

  • 50% Lighter

    A 100Ah LiFePO4 weighs 25 lbs. The lead-acid equivalent? 65 lbs. On a boat, that matters.

  • 2X Usable Capacity

    Lead-acid should only be discharged to 50%. LiFePO4 gives you 80–100%. A 100Ah lithium outperforms a 200Ah lead-acid.

  • 10X Cycle Life

    3,500–5,000+ cycles vs. 300–500. Replace once a decade instead of every two seasons.

  • 4X Faster Charging

    Accepts charge at higher rates with no absorption taper. Shorter generator run times, faster solar recovery.

  • BMS (Built-In Protection)

    Every LiFePO4 battery includes a battery management system – overcharge, over-discharge, short circuit, and thermal protection built in.

LiFePO4 Batteries for Canadian Winters

If you're buying LiFePO4 batteries in Canada, cold weather isn't an afterthought – it's the primary design constraint. Here's what you need to know: LiFePO4 cells discharge fine in cold temperatures, even below -20°C. The problem is charging. Pushing current into a lithium cell below 0°C risks lithium plating on the anode, which permanently damages the battery.

That's why we stock self-heating LiFePO4 batteries from Epoch and ReLiOn. These units have internal heaters that activate automatically when cell temperature drops below a set threshold – typically around 0°C to 5°C. The heater draws a small amount of energy from the battery itself (or from a connected charging source) to warm the cells before accepting charge. It's not a gimmick – it's the difference between a battery that lasts 10 years and one that's degraded after two Canadian winters.

Victron-compatible batteries take it a step further. The Epoch Elite V2 series, for example, communicates cell temperature directly to Victron charge controllers and inverter/chargers. The charger won't push current until the cells are warm enough. That's system-level protection you don't get with budget brands.

LiFePO4 Battery FAQ

What is a LiFePO4 battery?

LiFePO4 stands for lithium iron phosphate – a specific lithium battery chemistry that uses an iron phosphate cathode instead of the nickel or cobalt found in laptop and phone batteries. The result is a battery that's more thermally stable, lasts significantly longer (3,500–5,000+ cycles), and is safer for marine, RV, and off-grid applications where reliability matters more than shaving a few ounces of weight.

LiFePO4 vs. lithium-ion – what's the difference?

LiFePO4 is actually a type of lithium-ion battery – just a different chemistry. Standard lithium-ion (NMC or LCO) uses nickel, manganese, or cobalt and prioritizes energy – great for phones, not ideal for a marine house bank. LiFePO4 trades a bit of energy density for dramatically better thermal stability, longer cycle life, and safer failure modes. That's why it's become the standard for boats, RVs, solar systems, and backup power – applications where the battery sits in a confined space and needs to last a decade.

Can I charge a LiFePO4 battery in cold weather?

Discharging in cold temperatures is fine – LiFePO4 cells will deliver power down to -20°C without issues. Charging is the concern. Pushing current into lithium cells below 0°C causes lithium plating, which permanently damages the battery. Self-heating models from Epoch and ReLiON solve this by warming the cells automatically before accepting charge. Victron-compatible batteries add another layer by communicating cell temperature to your charger, preventing cold-charge damage at the system level.

How long do LiFePO4 batteries last?

Most quality LiFePO4 batteries are rated for 3,500 to 5,000+ charge cycles at 80% depth of discharge. In practical terms, that translates to 8–12 years for typical marine, RV, or off-grid use. Compare that to lead-acid batteries, which typically last 300–500 cycles or 2–3 years. The upfront cost is higher, but the total cost of ownership over a decade is significantly lower with LiFePO4.

Can I replace my lead-acid batteries with LiFePO4?

In most cases, yes – LiFePO4 is a drop-in replacement for standard lead-acid batteries (Group 24, 27, 31 sizes). The main thing to check is your charger. LiFePO4 batteries require a lithium-compatible charge profile – the absorption and float voltages are different from lead-acid. Many modern Victron and Epoch chargers support lithium profiles natively. If yours doesn't, you'll need to either adjust the settings or upgrade the charger. We can advise on compatibility for your specific setup.

What size LiFePO4 battery do I need?

It depends on what you're powering and for how long. A rough approach: calculate your daily energy consumption in watt-hours, divide by your battery voltage, and add 20% buffer. For a trolling motor running 4 hours at moderate thrust, a 100Ah 12V battery is often sufficient. For a full RV house bank with fridge, lights, and inverter, you're looking at 200–400Ah at 12V. Not sure? Contact us with your setup details and we'll size it for you – no charge.

Do you ship LiFePO4 batteries across Canada?

Yes – free shipping on all battery orders across Canada. We ship from our warehouse in Ontario. LiFePO4 batteries are classified as dangerous goods for air freight, so all battery shipments travel by ground. Delivery times vary by province but typically range from 3–7 business days.
