Beyond Batteries: How FTI’s Custom Lithium Power Packs Transform Marine, Industrial & Off-Grid Energy

A battery is easy to buy. A power system that fits your vessel, your plant or your remote site is something else entirely. That is the gap FTI’s custom lithium power packs are built to close.

Across Saudi Arabia and the wider Gulf, operators are replacing lead-acid banks and generic lithium modules with energy systems designed around their real working conditions. The reason is simple: when power is mission-critical, “close enough” is expensive.

Why off-the-shelf batteries fall short

Standard packs are engineered for the average customer. Marine, industrial and off-grid users are rarely average.

• Marine: salt-laden air, constant vibration, tight engine-room spaces and strict class requirements punish ordinary enclosures and connectors.
• Industrial: heavy duty cycles, high peak loads and long uptime targets expose weak cells and basic protection circuits.
• Off-grid: extreme heat, daily deep cycling and difficult access make maintenance visits costly and failures disruptive.

What “custom” really means at FTI

Customization at FTI goes well beyond choosing a voltage. Each pack is designed as a complete system, starting from the application and working back to the cells.

• Chemistry and cell selection: typically lithium iron phosphate (LiFePO4) for its safety profile and long cycle life, or other lithium-ion chemistries where energy density matters most.
• Voltage, capacity and current: sized to your real load profile, with headroom for peaks, rather than forcing you into a catalogue size.
• Battery Management System (BMS): protection against over-charge, deep discharge, over-current, short circuit and temperature extremes, plus cell balancing.
• Mechanical design: custom form factors, rugged and sealed enclosures, vibration-resistant mounting and marine-grade connectors.
• Communication: integration with chargers, inverters and monitoring systems through standard industrial protocols.

Built for three demanding environments

Why lithium makes the difference

Compared with traditional lead-acid systems, a well-engineered lithium pack offers a clear set of advantages:

• Longer life: thousands of charge cycles, which lowers cost per cycle over the system’s lifetime.
• Lower weight and size: more usable energy in less space, which matters on vessels and mobile equipment.
• More usable capacity: deeper discharge without damaging the battery, plus stable voltage under load.
• Faster charging and low maintenance: no topping up, less downtime and fewer service visits.

Safety, quality and compliance

Lithium energy demands engineering discipline. FTI’s approach combines careful cell matching, multi-layer BMS protection, thermal management and structured testing before any pack ships. Our work is aligned with ISO global quality standards, and packs can be prepared to meet the transport and safety requirements relevant to your market and sector.

Support that lasts the full lifecycle

A power pack is only as good as the support behind it. With engineering hubs across Saudi Arabia, Pakistan, Jordan and China, FTI supports customers from first concept through prototyping, production, installation guidance, repair and reconditioning. When a pack needs attention, our teams diagnose and restore it rather than leaving you to replace the whole system.

How to get started

1. Share your requirements. Tell us your application, voltage, expected load, space limits and operating environment.
2. Engineering review. Our team recommends chemistry, capacity and BMS features that fit your use case.
3. Prototype and test. We build and validate a sample against your real conditions.
4. Production and support. Scale to full delivery with ongoing technical backing.

The bottom line: custom lithium packs are not just a battery upgrade. They are a smarter way to power marine, industrial and off-grid operations with more reliability, less downtime and better long-term value.
