Titan 12v lithium iron phosphate (LiFePO₄) leisure battery 120Ah

Titan 12v lithium iron phosphate (LiFePO₄) leisure battery 120Ah

12.8V | 120Ah | 1,536Wh

Real achievable capacity - up to 128Ah

280mm long x 175mm wide x 190mm high

Built for VW T6, custom campers and low-profile conversions where the standard DIN 019 case won't fit but you want serious capacity. 150A continuous BMS output, native Victron CANBUS, built-in heater and dual active and passive cell balancing.

The BMS is upgraded to 150A continuous output. This compact model keeps things simple: full Bluetooth monitoring through the TITAN® app, built-in heater and dual active and passive cell balancing, but no inverter comms ports.

• 1,536Wh usable, up to 128Ah in practice
• 150A continuous BMS discharge
• 11.5kg 
• Native Victron canbus 
• Built-in heater mat, safe charging down to -30°C
• Lifetime, transferable warranty

Case height is 190mm as standard. It can be mounted on its side to drop overall height to 175mm where fitting space is tight.

The cell chemistry

All TITAN® batteries use lithium iron phosphate (LiFePO4) prismatic cells - the most thermally and chemically stable lithium chemistry available. No cobalt, no nickel, no off-gassing, no acid. The trade-off is a slightly lower cell voltage (3.2V per cell, 4 cells = 12.8V) and lower energy density than the NMC cells used in EVs. In return, you get lifespans that make NMC look disposable: 3,000 to 25,000 cycles depending on use, against NMC's 1,000 to 2,500.

LiFePO4 is now widely considered safer than lead-acid. Cells can be installed in any orientation (upright is optimum), contain no liquid electrolyte, and are fully recyclable.

Cycle life you won't outlive

A cycle is one full discharge plus one full recharge. Count scales with how deep you take each discharge:

• 100% DoD - 3,000 cycles (8.2 years at one cycle a day)
• 80% DoD - 6,000 cycles
• 50% DoD - 12,000 cycles (over 30 years daily use)
• 30% DoD - 15,000+ cycles

Inverter and device communication

For reference, the best lead-acid gel battery tops out at 350-400 cycles at 80% DoD. A TITAN® at the same depth gives 6,000 - roughly 15x the service life.

Comms ports on the case let the battery talk to compatible inverters, chargers and GX devices. Defaults to Victron CANBUS (VE.CAN and BMS.CAN) and is compatible with Victron DVCC out of the box.

Bluetooth monitoring

Bluetooth is built in. The free TITAN® app (iOS and Android, 10 languages) shows live voltage, current in both amps and watts, SOC as a percentage and in Ah, individual cell voltages, internal temperature, estimated time to full or empty, protection trip history and live balancing activity.

It handles multiple batteries in series or parallel and re-calculates totals automatically, so whether you've got one 120Ah or three in parallel, the figures on screen match the actual pack.

Warranty, longevity and repair

Actual lifetime warranty

We're confident enough in the build to back every grade-A cell battery with a warranty that lasts the lifetime of the battery - fully transferable. Our parent company has been trading continuously since 1948, so we intend to be around to honour it in 20 years' time.

What the warranty doesn't cover is wear. All batteries lose capacity with use - the harder you work them, the faster that happens. LiFePO4 is remarkably resistant: expect a 5-10% capacity drop every decade of normal use. Natural degradation isn't a valid warranty claim - if a battery stops holding enough capacity for your use, it's time to replace.

The warranty covers components against premature failure caused by manufacturing faults. Full terms are on our warranty page.

Module-based repair

If something fails we repair the failed module - BMS, balance board, a single cell - rather than replace the whole battery. Lower cost to you, lower carbon footprint, faster turnaround. As a family of battery specialists since the 1950s, there isn't much we haven't already rebuilt.
