Compact Power Density Built for Mini Excavators

The 51.2V 410Ah lithium energy pack is engineered specifically for compact and mini excavators working in tight, space-constrained job sites — utility trenching, landscaping, urban demolition, and indoor or noise-sensitive environments. Delivering roughly 21 kWh of usable energy in a footprint that fits mini excavator battery bays, this pack replaces bulky lead-acid or diesel power without sacrificing digging force or hydraulic response. By integrating BSLBATT LiFePO4 technology, contractors get a full shift of quiet, zero-emission digging on a single charge — with the flexibility to top up during breaks instead of swapping batteries.

  • Battery Technology: High-Grade LiFePO4 (Lithium Iron Phosphate)
  • Case Design: Reinforced Heavy-Duty Steel (Standard Industrial Design)
  • Vibration Resistance: Meets industrial forklift shock and vibration standards for high-rack stability.
  • Communication Interface: CANbus / RS485 (Compatible with communication protocols from Toyota, Hyster, Yale, and others)
  • Charge Time: < 2 Hours (Supports rapid opportunity charging)
  • Heat Management: Integrated PDU (20% Enhanced Cooling)
  • Safety Standards: CE, IEC, UN38.8, Sedex

Eliminate Downtime and Diesel Costs on Compact Jobsites

No More Mid-Shift Power Loss: Mini excavator operators lose productivity every time a lead-acid battery needs replacing or a diesel unit needs refueling. Our 410Ah LiFePO4 pack maintains a flat discharge curve with no voltage drop at the end of a shift, so digging force, swing speed, and hydraulic response stay consistent from the first bucket to the last — even across multiple shifts with opportunity charging in between.

Built for Tight, Demanding Work Environments: Mini excavators often work in confined trenches, wet ground, and dusty demolition sites. The IP65-rated, fully sealed battery case protects internal cells from moisture and debris, while the automotive-grade shockproof design withstands the constant vibration of digging and travel. This removes the maintenance burden of watering, acid top-ups, and corrosion checks that come with lead-acid packs — cutting Total Cost of Ownership and unplanned downtime.

  • Full-Shift Digging Without Battery Swaps

    At 410Ah, this pack gives compact excavators the endurance to run a full workday through opportunistic charging during natural breaks, eliminating the need for spare batteries, dedicated charging rooms, or diesel refueling stops. This keeps small crews productive without adding logistics overhead.

  • Stable Torque for Precise, Consistent Digging

    The 51.2V system delivers a flat, stable discharge curve, so bucket force and swing torque remain consistent whether the battery is at 90% or 20% state of charge. For operators working in confined trenches or near structures, this predictability means safer, more precise digging throughout the shift.

  • Jobsite-Ready Safety and Protection

    With IP65 sealing, flame-retardant insulation, and an automotive-grade shockproof structure, this battery is built to survive dust, mud, rain, and constant vibration. An intelligent BMS continuously monitors voltage, current, and temperature, cutting power automatically if any parameter moves outside a safe range — protecting both the machine and the operator.

  • Remote Fleet Visibility for Rental & Multi-Machine Operators

    With optional GPRS + GPS cloud connectivity, fleet managers can monitor state of charge, diagnose issues remotely, and track machine location and usage across multiple mini excavators from one dashboard — reducing unplanned breakdowns and simplifying maintenance scheduling for rental fleets and multi-crew contractors.
