Extremely safe and stable chemistry: PCB and/or BMS built inside to balance and protect the battery.
Long life-cycle: Can be circularly used, best can up to 1000 times recycles.
Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.
Good performance at high temperatures and high-temperature resistance.
Low self-discharge rate, less than 3% monthly.
No memory effects and a highly efficient charge.
Environment-friendly: Clean and Green energy poses no pollution to our environment.
No maintenance. That means no watering, no acid, and no corrosion. Also, there is no need for rubber gloves and safety glasses when handling our batteries.
Tested and Safe.
Impress Lithium-ion Batteries has over 12 years of experience in safety. The Lithium chemistry used in our batteries is much safer than lead-acid which produces harmful by-products (lead and acid) that are hazardous materials.
Our BMS (battery management system) will detect any problems with the performance of the battery and shut down any cells not functioning properly. The BMS will also protect the batteries from any over-charging or undercharging of the batteries.
2-3 Hour Fast Charging.
Charging: A full 48V Lithium-ion e-bike Battery setup will charge in 2-3 hours versus normal lithium batteries that require 4-6 hours.
Opportunity Charging: This means you can top off your Lithium Batteries any time you want without harming the batteries (just like your cell phone). You cant do this with Lead Acid without damaging and reducing the life of the batteries.
Q. What are the advantages and disadvantages of lithium batteries and lead-acid batteries in electric vehicles?
A: Lead-acid battery technology is simple and cheap, short charging, and discharging life average 300 to 500 times, heavy volume, serious pollution of the environment, and harmful to the human body.
Lithium batteries with the same capacity are one of the 5 parts of the weight of lead-acid, long charging and discharging life: ternary polymer lithium charge and discharging times 1000 times, the highest lithium iron phosphate charge, and discharging life up to 3000 times, green environmental protection. Disadvantages: the price is higher.
Q. Is there a big difference between lead-acid batteries and lithium batteries in winter?
A: Ordinary lead-acid batteries generally operate at a minimum temperature of around -15 degrees Celsius, while lithium batteries can operate at -40 degrees Celsius, making it easier to start cold in winter. And lithium batteries are relatively light, many teachers after work parking lithium batteries to take home, easy to charge and safe. Now the price of lithium batteries has been much cheaper, do not need maintenance, cost-effective than lead-acid batteries are higher.
Q. What is the relationship between electric vehicle voltage and performance?
A: The voltage of an electric vehicle is proportional to its performance. The higher the voltage, the higher the power, the higher the speed and the power, and the larger the battery capacity, the longer the battery life, and the longer the range. Therefore, in terms of technical content, the higher the voltage, the better the performance and economy of the electric vehicle.
