An LFP pack is only as good as its charger. The wrong profile will degrade cells, trip BMS protections, and shorten warranty life.

Key decisions: 0.5C vs 1C charge rate, off-board vs on-board, REMA vs SB connectors, and how to wire charge inhibits into the truck's ignition circuit. We walk through each below.

Wattrae ships matched chargers with every conversion, profile-tuned at the factory to the cells in the pack.

Fast charging (1C) refills a pack in roughly an hour. Opportunity charging tops up the pack during operator breaks throughout the shift.

The right answer depends on shift length, break frequency, and whether trucks are pooled or assigned. We walk through three real-world shift patterns and the charging strategy each one calls for.

Sizing an LFP pack for a forklift starts with the duty cycle, not the lead-acid nameplate. Lead-acid is typically oversized for usable capacity (50% DoD); LFP is rated to 95–100% DoD.

We walk through a step-by-step calculation: average current draw, shift length, opportunity-charge windows, and a 20% headroom margin. The same approach applies to AWPs and pallet trucks.

A typical 48V golf cart runs 6×8V flooded blocks. Replacing them with a single sealed 48V LFP pack changes the weight distribution, the charge profile, and the state-of-charge gauge.

What stays the same: the motor controller, the solenoid, and the chassis. What changes: charger profile, BMS wiring, and the SOC display. We cover each topic in detail.
