A SYSTEM UPGRADE

From lead-acid
to lithium.

A better replacement starts with the equipment you already have. Match the battery, charging and installation together before you place a bulk order.

CHOOSE YOUR APPLICATION

Different systems. Different checks.

Use the existing product pages for specifications. A replacement project uses the same model record, with a separate system review.

BEFORE YOU CHANGE THE BATTERY

Four checks for the complete system.

Lead-acid conversion checklist
CheckWhat to provide
Existing systemVehicle / equipment model, old battery label, number of batteries, series arrangement and present charger.
Electrical compatibilityOperating voltage window, continuous and peak load, regenerative charging and BMS protection behaviour.
Charging & auxiliariesCharger profile, charge voltage / current and any DC-DC converter or inverter. An old lead-acid charger is not automatically suitable.
Installation & evaluationBattery tray, mounting, terminal clearance, cable sizing and protection. Agree a sample test in the complete system.

Start with the old battery label.

Send the vehicle or equipment model, battery label, charger label and installation dimensions by email or WhatsApp. Our team can use these to begin the compatibility review.

Discuss the conversion

COMPARE THE COMPLETE COST

More than a price per Ah.

Evaluate usable energy under your duty cycle, charging time, charger or wiring changes, maintenance and service arrangements. Savings depend on the actual installation and use.

Is it a drop-in replacement?

Only when the exact electrical, mechanical and charging requirements have been checked. A matching case or a familiar voltage label does not establish compatibility.

Can I connect packs in series or parallel?

Use only arrangements approved for the selected battery and BMS version. Share the proposed configuration and system drawing; the connection limits are confirmed during review.
