iTECH50S 50Ah 12V Lithium-ion Battery LiFePO4

We are introducing our latest lithium battery, the iTECH50S. Perfect for running a fridge and powering 12v appliances the iTECH50S goes where no lithium battery has gone before thanks to its slimline design.  Fitted with mounting brackets so it can fit in the tightest of spaces. Will fit behind the seat of any dual cab ute. Has 2 handy Anderson connectors for charging or discharging. Also features a 12v car output where you can plug in any 12v device with a 12v car adapter.


BMS/OPERATING SYSTEM: 100% of the iTECH50S's capacity is usable. The internal BMS allows 50A continuous discharge. The iTECH50's internal BMS controls cell balancing, over and under-voltage protection, short circuit protection, thermal protection, and has over-discharge protection (safe mode).

CAPACITY: The iTECH50S's 50Ah Lithium-ion is the equivalent to about 110Ah in lead-acid batteries (based on the standard depth of discharge of the iTECH50S (100%) and lead-acid battery (50%).

WEIGHT: The iTECH50S weighs just 7kg the equivalent lead-acid battery weighs 27+kg.

USE MOST CHARGERS: The iTECH50S will charge up to 5x faster than lead-acid batteries. The iTECH50S can charge from just about all existing chargers with no extensive modifications required to existing systems.

LIFE SPAN: The iTECH50S can cycle up to 5000 times at 50% depth of discharge. A lead-acid equivalent can cycle up to 500 times at a 50% depth of discharge. The iTECH50S has little to no self-discharge rate (≤2%), the battery can sit for long periods and will not go flat.

AUSTRALIAN: Designed and developed in Australia for use with caravans, camper trailers, motor homes, 4WD, boats, yachts, trucks and everything in-between. The iTECH50S will operate flawlessly in extreme heat and will handle heavy vibrations usually associated with corrugated roads.
