Key Features
25A High-Current Output
Delivers 25A@220Vac charging current — cutting charging time by up to 28% vs. conventional 48V chargers. Ensures rapid turnaround for commercial fleets.
IP65 Dustproof & Waterproof
Fully sealed against dust ingress and low-pressure water jets. Ideal for outdoor charging stations, delivery routes, and all-weather commercial environments.
CAN-bus Communication
Seamlessly integrates with vehicle BMS via CAN-bus protocol. Dynamically adjusts charging parameters to extend battery cycle life and protect cell health.
Battery Activation Function
Detects and revives over-discharged batteries that standard chargers cannot recognize — recovering deeply discharged lead-acid, sodium and lithium packs before normal charging begins.
3-Colour LED Status Indicator
External LED shows real-time charging status: Red (Charging) → Green (Full) → Yellow (Fault). Enables quick fleet monitoring without opening compartments.
UL Certified & 6-Layer Protection
UL certified for North American market compliance. Six independent protection layers: over-temperature, reverse polarity, short-circuit, no-load, full-charge auto-shutdown, and under/over-voltage.
Charge Interlock
Prevents arcing and sparking during connector plug-in/plug-out. Critical safety feature for work sites with flammable materials or high-traffic charging areas.
Ultra-Compact & Lightweight
110×132×68mm footprint and 2.3KG weight fits naturally into golf cart compartments, tricycle storage bays, and UTV racks — zero installation compromise required.
Protection Functions
When internal temperature exceeds the preset value, charging current automatically decreases. If ambient temperature exceeds 65°C, the charger shuts down and resumes automatically when temperature returns to normal.
If the battery is connected in reverse, the internal circuit disconnects from the battery, preventing damage to the charger and the battery system.
No output when no battery is connected, preventing energy waste and eliminating idle hazards at unattended charging stations.
When the output is short-circuited, the internal circuit immediately disconnects from the battery. Charging can only resume after the fault is cleared and the battery is reconnected.
Charger automatically shuts down when the battery is fully charged (3A shutoff current), preventing overcharging and extending battery cycle life by up to 32%.
Continuous monitoring with under-voltage and over-voltage protection ensures stable charging even in regions with fluctuating power grids.

Application Scenarios
Golf Carts: Reliable Performance for Course Operations
Golf carts require consistent, quiet, and safe charging to support daily course operations, and the BS1350A-4825 excels in every aspect. Its compact size (110×132×68mm) and 2.3KG lightweight design fit seamlessly into golf cart storage compartments or course charging stations, without occupying extra space. The ≤45dB ultra-low noise operation preserves the serene atmosphere of golf courses, while the external 3-colour LED indicator allows staff to quickly monitor charging status (Charging/Full/Fault) for efficient fleet management.
With 25A high current charging, golf carts can be rapidly rotated between rounds, ensuring no delays for players — even during peak hours. The CAN-bus and battery activation functions intelligently sync with the cart's BMS, optimizing charging parameters to extend battery life — a key cost-saving benefit for course operators.
Electric Tricycles: Durable & Efficient for Commercial Use
Electric tricycles — widely used for cargo delivery, passenger transport, and utility tasks — demand a charger that can withstand frequent use and harsh environments. The BS1350A-4825 meets this need with an IP65 dustproof and waterproof rating, shielding internal circuits from dust, rain, and road debris common in urban or rural settings. Its 25A high output current efficiently charges large-capacity tricycle batteries, ensuring all-day operation for delivery drivers or passenger transporters without lengthy downtime.
The sixfold protection system (over-temperature, reverse polarity, short-circuit, etc.) safeguards against accidental damage from rough handling or incorrect wiring — a common concern in high-frequency commercial use. Additionally, the global 100~240Vac input voltage compatibility allows it to be used in any region, making it ideal for fleet operators with international operations.
Electric UTVs: Rugged Power for Off-Road & Work Sites
Electric UTVs are built for tough conditions — construction sites, farms, hunting trails, and recreational off-roading — and their charger must keep up. The BS1350A-4825's IP65 rating and wide working temperature range (-20~50°C) ensure reliable performance in dust, mud, and extreme temperatures, from freezing winters to scorching summers. The 25A high current caters to UTVs' high-power motors and large battery packs, replenishing energy quickly after off-road adventures or full-day work shifts.
UL certification and comprehensive safety protections provide peace of mind, even when charging in remote or unmonitored areas. The charge interlock function prevents sparking during plug-in/plug-out, a critical safety feature for work sites with flammable materials or crowded environments.
Universal 48V Versatility: Beyond Core Vehicles
While optimized for electric tricycles, golf carts, and electric UTVs, the BS1350A-4825's versatility extends to other 48V electric vehicles, such as utility carts, low-speed electric trucks, and recreational off-road vehicles. Its 39–60Vdc wide output voltage range covers the full 48V battery system spectrum for both lead-acid, sodium and lithium chemistries. The combination of high power, robust protection, UL certification, and compact design makes it a top choice for both commercial fleet operators and individual users — delivering consistent, reliable charging performance wherever 48V electric vehicles are in use.
