Charging Mode

• Charging Desulfated: During the recharging process, high frequency desulfation pulse is output to the battery, which can break the coarse sulfate crystal of the battery plates, improve the electrochemical activity of the battery and restore its capacity.
• Charging voltage depolarized: During the recharging process, the output desulfation pulse has a negative pulse, which can effectively eliminate the polarization voltage in the charging link, increase the battery charging tolerance, accelerate the charging speed and improve the charging effect.
• Pulse Maintenance: When full or non-charged, it has pulse maintenance function, which can prevent battery re-sulfation and delay the battery aging.
• Prevent sulfation and support discontinuous charge: full-range pulse charging can effectively prevent lead sulfate from rebuilding, short-term sulfation caused by undercharge or short-term battery charged due to emergency situation. The capacity can be restored after continuous pulse charging cycle.

Technical Function

1)Pulse maintain for battery lifespan extension

2)Increase drive mileage

3)Full-range Pulse Charging Maintenance

Positive pulse eliminating sulfide crystallization; Negative pulse eliminating polarization voltage; Preventing water loss and gas evolution; Real-time control of battery charging temperature

Has positive and negative pulses, continuously smart adjust, eliminate sulfated crystals of EV batteries, so that the plate always maintains a "clean" state, improve battery capacity, then prolong battery life.

Usually,most of chargers on the market increase the charging current, resulting in water lost during charging and the deformation of charging bulging, leading to scrap

4)Resonance pulse, Non-damaged Repairing Battery and Cells balance of battery charging

5)Safety  Function

Charging Tips

• Battery nominal capacity is based on 25℃. For every drop 1℃, battery capacity decreases by 1%. Driving mileage in winter is about 50% of that in summer. In winter, the battery deep cycle capacity is lower, the electrolyte viscosity increases, the chemical reaction resistance increases, and the charging time shortens (below 5 ℃, charging 70% only). Charging 60-70% and discharging 50-60% reduce the mileage naturally. In winter, mileage calculation (70% charging * 60% discharging equals 50% as mileage in summer). Suggestions that charging your battery indoor (charging whenever you ride a bicycle)
