Lithtech 12V Lithium LiFePO4 Battery — The autonomy that transforms a conversion (100Ah / 200Ah / 314Ah)

The real bottleneck in vanlife is almost never solar or the charger — it’s the battery that collapses at half discharge, ages in two years, and can’t handle full use. The Lithtech LiFePO4 12V range solves this problem: lithium iron phosphate technology, smart BMS, Bluetooth monitoring, up to 6,000 cycles.

Available in 100Ah, 200Ah, and 314Ah, R10 certified, compatible with Victron, EcoFlow, Renogy, Carbest. Also available in a complete electrical kit with DC/DC, MPPT, AC/DC, distribution box, and fuses.

Why choose this battery

• 95% usable capacity — deep discharge without degradation, compared to only 50% in AGM/gel. Nearly double the actual available energy at equal capacity.
• Up to 6,000 cycles — several years of intensive daily use without significant degradation.
• Integrated BMS + full protections — short circuit, overcharge, deep discharge, overcurrent, over/under temperature, automatic cell balancing.
• Bluetooth monitoring (iOS & Android) — charge status, health, history in real time from your phone.
• Stable output voltage — your fridge and inverter won’t drop out at 60% load, unlike lead batteries.
• Light and compact — about half the weight of a lead/gel battery with equivalent energy.
• Self-discharge ≤ 3.5%/month — leave the van in the garage during winter, your energy will be ready in spring.
• Almost no maintenance — no electrolyte, no special ventilation, no fumes.
• R10 Certified — vehicle approval, essential for professional conversions.

Why LiFePO4 changes everything

Unlike lead or gel batteries, LiFePO4 maintains a stable output voltage until almost fully discharged: your lighting doesn’t dim, your fridge doesn’t stop, your inverter doesn’t drop out at 60% state of charge. The BMS continuously manages each cell, balances voltages, cuts charging in case of overvoltage or out-of-range temperature, and blocks discharge before any irreversible damage. On the Bluetooth side, the free app displays SOC, voltage, current, temperature, and long-term health — allowing you to properly size your system and detect drift before it becomes a problem.

Which model for which project

The 100Ah is the backup autonomy: LED lighting, phone/laptop charging, water pump, small fridge. Compact size, ideal as a complement or for weekend vans.

The 200Ah is the versatile standard for a semi-permanent vanlife: daily compressor fridge, diesel heater, water pump, lighting, recharges, small inverter. The best balance of capacity/weight/size.

The 314Ah is true long-term autonomy: van in permanent use, high-power inverter, induction, air conditioning. The BMS 200A handles peaks without triggering the protection cutoff.

Compatible with your setup

Designed to integrate with Victron ecosystems (Phoenix, Multiplus, MPPT SmartSolar, BMV/SmartShunt), EcoFlow, Renogy, and Carbest. For a complete project, find it in our Victron wiring kit with DC/DC booster, MPPT, AC/DC charger, distribution box, and pre-sized fuses.

Frequently asked questions

Really 95% usable discharge? Yes — this is the fundamental difference with lead/gel, where going below 50% drastically reduces lifespan.

What about safety? The BMS automatically cuts off in case of short circuit, overload, deep discharge, or out-of-range temperature. LiFePO4 is one of the most thermally stable lithium chemistries — much more than a classic NMC/NCA.

Hard to install? No. Standard M8/M6 terminals, dimensions close to an equivalent lead battery, no maintenance, no special ventilation.

And in extreme cold? Discharge down to −20 °C. Charging is blocked by the BMS below 0 °C to protect the cells — normal behavior for any LiFePO4. For winter in the mountains, plan an insulated compartment (or the self-heating version).

Real lifespan? Up to 6,000 cycles — more than 16 years at one full cycle per day. For weekend and holiday use, you’re looking at the vehicle’s lifespan.
