Product Description

We're often asked what makes our products better than other trickle or float chargers on the market. It's easy – our patented 36V/48V/60V/72V battery smart pulse technology! No other EV battery chargers on the market have this technology in the world. This 48V eBike Charging Maintainer device is a new type of Electric Bicycle Battery Repair tools, it is:

  • A kind of eBike Battery Charging Partner with pulse desulfation technology, Smart, Simple and Safe

  • Ensure the eBike driving mileage is longer
  • The connection with charger is simple, safe and convenient. Make your common charger become a Smart Charger with Battery Care function
  • Suitable for the popular 36V~72V batteries of electric vehicles, buy a set, multi vehicles benefit in family
  • A strict circuit filtering technique, does not affect the charging parameters of the charger, safe and carefree

Most of Electric vehicle use lead-acid battery bank(12V/6V/8V cells packed in Series)as the power source, The design lifespan of battery is 2~3 years, but actually the battery is usually failure after 6~12 months used which State-of-Capacity gradually decline and even some scraped. Through analysis by cutting a large number of failure batteries, the cells water loss and sulfation is quite prominent. Such as the phenomenon of battery sulfation and dehydration can be effectively prevented to prolong the service life greatly up to 2 times.

Our 4EVT BR-48S eBike Battery Charging Repairer is a new generation of high-tech products developed specifically for recovering electric vehicle battery when it is charging every time. It utilizes the energy from the charger to generate electronic pulse waveform with special frequency and strictly controlled rise time, which resonance with the thick sulfate crystals during charging process to continuously dissolved the lead sulfate crystals. Your battery capacity will be gradually recovered everyday and duo to under the disturbance of the specific frequency pulse, the sulfated crystallization re-buildup can be prevented effectively, therefore the battery service life can be prolonged to the maximum.


It is used for 36V/48V 7-40Ah Electric bicycle and motorcycle lead-acid battery bank.

It is not suitable for these battery banks with cell deformed appearance, positive plate softening and corrosion, active material shedding, short circuit, open circuit.


1) Environmental Conditions

  • Working Environment Temperature: -10℃~50℃
  • Storage Environment Temperature: -40℃~70℃
  • Relative Humidity of Environment: 45% ~90%RH

2) Electrical Parameters

  • Working Current: 36V Battery Mode: ≤65mA 48V Battery Mode: ≤80mA
  • Pulse Peak Current: 36V Battery Mode: ≥4,0A 48V Battery Mode: ≥6,0A
  • Maximum Voltage: DC80V
  • Frequency Range: 7,5kHz~10kHz


  • Step 1: Before used, first check the polarity of the charging port on the battery bank, It should be consistent with the input and output polarity of the bottom of the Battery Charging Restorer device to be used, otherwise it will damage the EVT BR-48S pulse charging desulfator device or your charger.
  • Step 2: Insert the charger output header into the EVT BR-48S Battery Charging Optimizer device input socket
  • Step 3: Let the output of the EVT BR-48S repair plug into the charging port of the battery bank
  • Step 4: The EVT BR-48S Battery Smart Pulse Charging Restore Device will automatically measure the battery voltage, if it is 36V battery Banks, "36V" indicator LED light, if it is a 48V battery bank, 48V indicator LED lights. After it is normal, please insert the input plug of the charger into the electrical outlet. The EVT BR-48S restorer device will remove sulfated crystals in the charging process.
