Description
Wattrae Energy 51.2V 375Ah LiFePO4 traction battery is engineered for Doosan B18T Counterbalanced Electric Forklift. It is prepared for lead-acid to lithium conversion projects with matched tray sizing, BMS protection, connector options, and charger support.
Lead-Acid to Lithium Replacement Overview
This 51.2V 375Ah lithium traction battery is positioned for fleets that want to replace flooded or sealed lead-acid batteries without changing the core truck workflow. The conversion should confirm voltage, battery compartment size, connector type, cable direction, counterweight requirement, charger profile, and communication needs before installation.
- Designed for Doosan B18T Counterbalanced Electric Forklift and similar industrial electric equipment.
- Supports opportunity charging and lower routine maintenance compared with lead-acid packs.
- Uses integrated BMS protection for over-charge, over-discharge, over-current, temperature, and short-circuit control.
- Can be matched with REMA, Anderson, or project-specific connectors and a compatible lithium charger.
- Tray size, ballast weight, cable outlet, SOC display, and CAN communication can be configured for the conversion project.

Lead-Acid Conversion Plan
- Record the existing lead-acid battery voltage, capacity, tray dimensions, weight, connector, cable exit direction, and truck model.
- Select a Wattrae Energy lithium pack with the correct system voltage, usable energy, BMS current rating, and required counterweight.
- Confirm charger compatibility, charging voltage, maximum current, connector standard, and any CAN or SOC display requirements.
- Install the battery in the tray, secure cables, verify polarity, test charger handshake, and run a controlled discharge/charge check.
- Train operators on opportunity charging, SOC reading, storage, and fault-code handling.
SEO FAQ
Can this battery replace a lead-acid forklift battery?
Yes, it can be used as a lead-acid replacement when voltage, tray size, weight balance, connector, charger settings, and discharge current are matched to the equipment.
Does the conversion need a new charger?
A lithium-compatible charger is recommended. The charger should match the battery charging voltage, current limit, connector, and BMS communication requirements.
Can the tray size and counterweight be customized?
Yes. For many forklift, pallet truck, reach truck, and tow tractor projects, tray dimensions, ballast weight, connector, cable outlet, and display options can be configured.
What information is needed before ordering?
Provide the truck model, existing lead-acid battery code, voltage, capacity, tray size, battery weight, connector photo, charger details, and operating duty cycle.
