We are introducing our latest lithium battery, the iTECH100. A massive 100 Amps of high-performance usable DC power coupled with a custom iTechworld Battery Management System (BMS) which ensures iTechworld's lithium batteries will outperform and outlast all others on the market.

100% of the iTECH100's 100 amp capacity is usable. The internal BMS allows a peak draw of 250 amps Peak power output to a peak draw of up to 250 amps with a sustained output of 175 amps for 5 minutes, and 150 amps continuously. The iTECH100's internal BMS controls cell balancing, over and under-voltage protection, short circuit protection, thermal protection, and has over-discharge protection (safe mode).

The iTECH100 100Ah Lithium battery is the equivalent to 200Ah in lead-acid batteries (based on the standard depth of discharge of the iTECH100 (100%) and lead-acid battery (50%).

To help address the heavyweight common with traditional battery storage, the iTECH100 weighs only 13kg, which is under 1/3rd the weight of an equivalent AGM or Lead Acid battery, which usually weighs more than 60kg each.

The iTECH100 will charge up to 5x faster than lead-acid batteries. The iTECH100 can charge from just about all existing chargers with no extensive modifications required to existing systems.

The iTECH100 can cycle up to 4000 times at 50% depth of discharge. A lead-acid equivalent can cycle up to 500 times at a 50% depth of discharge. The iTECH100 has little to no self-discharge rate(≤2%), the battery can sit for long periods and will not go flat.

Designed and developed in Australia for use with caravans, camper trailers, motor homes, 4WD, boats, yachts, trucks and everything in-between. The iTECH100 will operate flawlessly in extreme heat and will handle heavy vibrations usually associated with corrugated roads.
