From diagnosing & repairing faulty packs to engineering high-performance custom battery packs for e-bikes, e-scooters, EVs, solar storage, and specialized industrial gear.
Fill out your details below and Dean will get back to you with a custom quote.
Whether you need to revive a dead battery or engineer a high-output custom pack from scratch, we cover every aspect of lithium battery technology.
Complete diagnostic, BMS replacement, cell balancing, and spot-weld repairs to bring dead or faulty battery packs back to life safely.
Bespoke lithium-ion and LiFePO4 battery pack design built to your precise dimensions, voltage, discharge rate, and capacity specs.
Upgrade factory stock e-bike or e-scooter batteries with high-energy grade cells for dramatically longer range and higher peak power.
Have a unique project? Solar storage, custom robotics, marine power, or prototype devices—we welcome custom engineering challenges.
Battery fabrication requires strict attention to thermal dynamics, spot weld integrity, and BMS calibration. We don't cut corners with cheap cells or unsafe enclosures.
Only tier-1 Samsung, LG, Molicel, and Panasonic cells used in every build.
Pure nickel strips and calibrated pulse welding for minimum resistance and maximum durability.
Integrated over-charge, over-discharge, short-circuit, and thermal protection on every pack.
Owner & Lead Battery Specialist
"At Melbourne Custom Batteries, every battery pack is handcrafted right here in Melbourne. Whether you're stranded with a faulty scooter pack or building a 72V custom monster, I personally test and inspect every weld and cell group before it leaves our workbench."
