Why Choose LiFePO4?

Lithium-iron-phosphate is the safest lithium battery chemistry, resistant to thermal runaway. It offers thousands of cycles and a flat discharge curve, making it ideal for solar and RV use. At $100, this is the ultimate upgrade for any 12V system.

Monitor Your Battery from Your Phone

With Bluetooth, you can check individual cell voltages, temperature, and state of charge using the VictronConnect app. This allows you to spot any issues early and maintain battery health.

Frequently Asked Questions

Which BMS is needed for Victron 12.8V 300Ah Smart Lithium battery?

You need a Victron VE.Bus BMS or similar Victron BMS (sold separately). The battery itself has cell balancing, but a BMS is required for overcurrent, undervoltage, and temperature protection. We recommend the VE.Bus BMS V2 for full integration with Victron inverters/chargers.

How do I wire the Victron VE.Bus BMS V2 with a 300Ah Smart Lithium battery?

Connect the battery’s M8 terminals to the BMS using appropriate thick cables (e.g., 2/0 AWG for 300A). The BMS then connects to the inverter/charger via VE.Bus and to the battery via the BMS cable. Follow Victron’s wiring diagram in the manual. Always fuse the positive cable.

Can I connect multiple 300Ah batteries in parallel?

Yes, you can parallel up to 20 batteries for a 12V system with up to 84kWh storage. Ensure each battery has its own BMS and that you use proper busbars and fuses for each battery. VictronConnect can monitor each battery individually.

What is the cycle life of this battery?

Victron states a cycle life of 5000 cycles at 80% depth of discharge and 3000 cycles at 100% DoD. This makes it ideal for daily cycling in off-grid systems.

How much can I save with this deal?

You’re saving 95% off the list price of $1950 – that’s $1850. Use coupon SAVE10 to save an additional $10, making the final price just $90. Free shipping on this item. This is a limited-time offer.

Perfect for our RV

Installed this battery in our fifth wheel last month. So far, it's been flawless. The Bluetooth monitoring is super handy – I can check the state of charge from my phone. Highly recommend for anyone upgrading from lead-acid.

Worth every penny

I've been using this Victron 300Ah for my off-grid cabin for three months now. It powers everything without a hiccup. The app is intuitive and the battery is lightweight compared to the old ones. Great investment.

Solid, but a bit pricey

This battery is top-notch quality, no doubt. The Bluetooth feature is cool and the capacity is generous. However, it's still expensive even with the discount. I'd definitely recommend it if you have the budget.

Excellent battery, easy install

Replaced two 12V AGMs with this single 300Ah. It was a straightforward swap. The Bluetooth setup was quick and I can now see voltage and remaining capacity clearly. Very happy with the performance.

Great so far

Only had it a few weeks, but it's been perfect for our marine setup. The battery holds charge well and the app is a nice touch. I deducted one star because it's still a bit heavy, but that's expected for this capacity.

Game changer

This battery is amazing. I'm using it for my tiny house off-grid, and it runs everything – fridge, lights, even a small TV. The Bluetooth monitoring is accurate and I love that I can see exactly what's happening. Worth the cost.

Charge drops quickly

I've had this for six months and the capacity seems to have degraded already. It used to run my fridge for two days, now only one night. Not what I expected from Victron. Disappointed.
