Electric bike battery

8-DZM-14
16V 20ah
Size: 248*98 *123*123mm
Weight: 9.7kgs

Product feature:
1. Large capacity, High specific energy: Made by special technology and material, capacity is more than 100%, specific energy reach 35-38wh/kg.
2. Low self-discharging: Made by high grade alloy grid, pure electrolyte, low self discharging and water loss.
3. Long durability: It can be used for 360 times at the temperature of 25, if maintained regulary, it can be used for 650 times.
4. Reliability: The streamlined valve is specially designed in order to make the battery durable and reliable.
5. Airtight structure: Could use battery in any direction(except inversion).
6. Excellent design: It is not only with the merit of seal valve regulation, but also with the advantage of maintenance. The special design of the extraction makes it easy to maintain and prolongs the durability by 50-100% or longer.
7. Various ways of use: Battery could be floating use, also be cycling use.
8. Recommended charging methods: 3-step charging.


Use and maintenance of products:
Battery: Red for positive polarity, blue for negative polarity. Battery should be series connection. The connection between battery pack and charge and discharge line is same polarity connection.
1. Batteries leave factory with charged so that clients could install and use directly. In order to remedy the capacity slef-discharge in the storage and transportation, new battery need to charge 4-8 hours to use.
2. Storage batteries should be installed by professionals.
3. We suggest charge temperature is 15-30. (Low temperature could reduce the battery's capacity. )4. Storage: Battery should be stored in 0-40 and maintain good ventilation. Avoid direct sunlight and keep away from heat.

Three kinds charge methods:
1. Use suitable charger, when red light change green, then continue to charge 4 hours, the battery full charge; After battery deep discharge(80% discharge capacity), charge time should be more than 12 hours.

2. Constant voltage current-limiting charging methods: Constant voltage 14.8V/pcs, charging current limiting values 0.15-0.20CA, charging hour 6-12 hours.

3. Constent Current chraging method: Charging with 0.10-0.20CA to battery voltage 14.8V/pcs(36V), battery pack 44.4V/set, then charging 4.5-6 hours with 0.05CA current could be full charge.

Discharge:
1. Discharge protection voltage should be more than 10.8V/pcs, Discharging protection current should be less than 1.5CA.

2. Batteries should be charged in time.

3. When vehicles don't use for a long time, batteries should be in full charge storage, and charge every 2 months.

Typical Applications
These products are widely used by electric bikes, electric motorcycles, electric scooters, electric tricycles, hybrid electric vehicles, power tools, Motorcycle, Electro-tricycle, E-bike, Scooter, Golf cart.
