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.\u003c\/p\u003e\n\u003cp\u003eLiFePO4 is now widely considered safer than lead-acid.

Cylindrical cells leave gaps between every cell and are much harder to repair (lots of spot welding), so we pay the extra cost for prismatic and pass the capacity gain back to you. The aluminium cell casing also disperses heat evenly: even at full 300A BMS allowance we measured peak cell temperatures around 45°C, well inside spec (thermal runaway territory doesn't start until around 100°C). Heater mats also work better with prismatic cells - every cell sits against the heating element, rather than only the outer ring of a cylindrical pack.\u003c\/p\u003e\n\u003ch2\u003eCapacity, without the weight\u003c\/h2\u003e\n\u003ch3\u003eEleven times the usable capacity of lead-acid\u003c\/h3\u003e\n\u003cp\u003eMatching this 460Ah in lead-acid means eleven Exide ER550 115Ah batteries paralleled up to 1,265Ah. One TITAN 460Ah replaces the lot - huge saving in space, weight and cabling, with no gassing so it can live anywhere.\u003c\/p\u003e\n\u003cp\u003eWe quote capacity in Wh (Watt-hours) because Ah on its own ignores chemistry. TITAN lithium delivers 100% of rated capacity. Gel manages around 90%, AGM 75%, flooded lead-acid 60%. Factor that in and a TITAN 460Ah has more than double the real-world capacity of a lead-acid battery on the same label rating.\u003c\/p\u003e\n\u003ch3\u003e39kg. Not 286kg.\u003c\/h3\u003e\n\u003cp\u003eThere isn't a single lead-acid battery that comes close to this capacity. The honest comparison is eleven ER550-class leisure batteries paralleled together to match the usable Wh - that's 286kg of lead-acid sitting in your install. One TITAN does it in 39kg. A 247kg saving matters on a motorhome's drive-axle plate, at the ferry scales, and at the pump.\u003c\/p\u003e\n\u003ch3\u003e99% electrically efficient\u003c\/h3\u003e\n\u003cp\u003eAlmost every watt you put in comes back out.

It's the difference between a lithium battery that lasts 15 years and one that self-destructs in two. Most brands fit an off-the-shelf board with generic parameters. We don't.\u003c\/p\u003e\n\u003ch3\u003eMatched, not off-the-shelf\u003c\/h3\u003e\n\u003cp\u003eOur BMS is custom, with parameters tuned to the exact cell spec we use. That lets us run the cells right up to their real safe working limits without compromising protection. It's also how we pull an extra 5-10% usable capacity out of every cell (a 460Ah can show as 485Ah fully charged). We can't guarantee the bonus capacity batch to batch, but the BMS re-maps its 100% reading automatically so the app always shows what you actually have.\u003c\/p\u003e\n\u003ch3\u003e11 protections, all self-resetting\u003c\/h3\u003e\n\u003cp\u003eOver-discharge, over-voltage, under-voltage, over-current, short-circuit, over-temperature, under-temperature, cell balance faults and more. All protections are temporary - they either self-reset or clear the moment the battery is put back on charge. The 300A continuous current allowance on this model is class-leading thanks to premium MOSFETs, oversized heat sinks and properly sized internal cabling.\u003c\/p\u003e\n\u003ch3\u003eDual active and passive cell balancing\u003c\/h3\u003e\n\u003cp\u003ePassive balancing is cheap: cells bleed off to each other and that's it. Active balancing actively moves energy between cells, protecting the weakest cell from doing all the work. Most brands pick one. We run both - passive for small voltage deltas, active for larger ones. Keeps the BMS's own power draw low while still giving you the full benefit of active balancing. It's automatic, most active when charging above 3.4V per cell, and takes full effect between 90-100% SOC.\u003c\/p\u003e\n\u003ch3\u003eSelf-heating, safely charging down to -20°C\u003c\/h3\u003e\n\u003cp\u003eLithium cannot be charged below 0°C without cell damage. Our built-in heater mat wraps the internal pack and kicks in automatically at around 2°C whenever there's an incoming charge current. It draws from the charger first, and if the charger can't keep up, pulls up to 3.6A from the battery itself to get cell temperature to 10°C before routing charge back to the cells. Expect roughly 20 extra minutes on your charge time in the cold. Discharge is unaffected and works down to -20°C.\u003c\/p\u003e\n\u003ch3\u003eAutomatic and user hibernation\u003c\/h3\u003e\n\u003cp\u003eA fully discharged lithium battery left for months can be a lithium battery that doesn't come back.
