The iTECHBC4 4A Intelligent Battery Charger is a fully automatic "set and forget" charger built to charge and maintain both Lithium LiFePO4 and lead-acid batteries fast, efficiently and safely. Using a 9-stage charging algorithm and the latest switch-mode charging technology, the iTECHBC4 doesn't just push current into a battery, it reads it, adapts to it, and looks after it.
The 9-stage process delivers a consistent, controlled charge with no voltage drop, then transitions automatically into a maintenance stage. That means the iTECHBC4 can stay permanently connected to your battery, keeping it topped up and healthy through weeks or months of storage without any risk of overcharging.
With charge profiles tailored specifically to Lithium LiFePO4 chemistry, as well as full support for conventional lead-acid batteries, the iTECHBC4 maximises and extends your battery's service life rather than shortening it. Its dedicated cold-weather mode adjusts the charge profile for low ambient temperatures, so the charger behaves correctly whether it's a Queensland summer or an alpine winter.
Like every iTechworld charger, the iTECHBC4 includes our innovative boost charge feature, which can activate an iTechworld lithium battery out of safe mode - recovering a battery that most chargers on the market simply won't recognise.
Designed and developed in Australia for the harsh Australian climate, the iTECHBC4 is the everyday charger for the car in the driveway, the 4WD start battery, the boat, the bike or the auxiliary battery that only gets used on weekends. A backlit LCD gives you live voltage, battery type, charge stage and state-of-charge at a glance, and a single one-touch MODE button cycles through every setting. Built-in protection covers short circuit, over-charge, reverse polarity and over-temperature, and the integrated rear hook lets you hang the unit rather than leaving it on the ground.
Supplied with both quick-connect battery clamps and a permanently-mountable eyelet/ring-terminal lead, the iTECHBC4 can be moved between vehicles in seconds or left hard-wired to a battery you charge regularly.
