The 500W Programmable & Adjustable Battery Charger is KSPOWER’s DSP intelligent high-performance charging solution — engineered for electric bicycles, electric scooters, small electric vehicles, and industrial battery charging applications. With programmable output voltage (10-90V) and current (1-10A), a multi-stage intelligent charging algorithm, and built-in fan cooling, it delivers fast, safe and efficient charging across a wide range of battery chemistries and pack configurations.
Advanced switching technology and high-quality components deliver up to 92% efficiency with low ripple noise and long service life. The charger is CE certified and accepts 200-240VAC input, covering European and Asian mains supplies. Optional plastic or aluminum alloy housing adapts the charger to different application environments — both rated for indoor use.
Programmable & Adjustable Output
Unlike fixed-voltage chargers, this 500W DSP charger lets you program the exact charging parameters to match your battery:
| Parameter | Adjustable Range | Typical Setting | Benefits |
| Output Voltage | 10V – 90V DC | 60V (e-bike 16S) / 88V (high-voltage pack) | One charger platform serves many pack voltages |
| Output Current | 1A – 10A | 8A @ 60V / 6A @ 88V | Match charge rate to battery capacity (0.5C-1C) |
| Charging Curve | Multi-stage (CC/CV/float) | Pre-set per chemistry | Chemistry-optimized: Li-ion, LiFePO4, lead-acid |
| Communication (opt.) | RS485 / CAN | Custom protocol | Remote monitoring, BMS integration, fleet management |
Voltage and current are adjustable to suit the specific battery pack — whether you are charging a 36V e-bike pack, a 60V scooter pack, or a 72-88V small EV pack. OEM programming of the charging curve is available for optimal battery cycle life.

| Reverse Polarity (optional) | Detects incorrect battery connection — prevents damage | Alarm + no charge output |
Built-in Fan Cooling & Thermal Design
The 500W charger uses a built-in fan cooling system with smart thermal management: the fan activates based on internal temperature, moving air across the power stage to maintain stable operation even during continuous high-power charging. Combined with ≥88-92% conversion efficiency (which minimizes waste heat at the source), the thermal design keeps internal components cool for long-term reliability.
