Description

Features

 

  • 12V 8Ah LiFePO4 Battery: Compared with traditional lead-acid batteries, WattCycle LiFePO4 battery is made of the latest lithium-ion material, the battery doesn't contain any heavy metal elements, it's safer and more environmentally friendly. The 12v battery has the advantages of high energy density, long cycle life, good safety performance and no harmful hydrogen gas.
  • Enhanced Internal Structure: WattCycle car battery adopts a square battery assembly, the new structure design makes the lithium battery more compact, which can enhance the working efficiency of the battery cell and ensure that there will not be any accidental situation such as power outage in the process of using. Compared with traditional large batteries, our deep cycle marine battery measures only 5.9x2.5x3.7inch and weighs only 2.2lb, which is even more compact, lightweight and space-saving.
  • IP67 Dust and Water Resistant: WattCycle LiFePO4 battery is designed with a compact case that is IP67 rated for dust and water resistance. High impact resistance battery case is made of non-conductive ABS plastic, which has strong resistance to impact, shock, chemicals and heat. The insulating material ensures that there is no leakage of electricity during use. It can be used normally even in rainy days, but you need to be careful that the POLES do not get wet.
  • Applicable to Many Scenarios: WattCycle 12v battery can be used in RV/outdoor camping, automobiles, boats, golf carts, trolling motors, wheelchairs, ride-on toys, computer back-up power, emergency lighting equipment, alarms, home energy storage, solar and wind energy storage, etc. When using it on ride-on toys, please choose a larger capacitor to avoid power failure caused by load protection. Please choose the appropriate battery capacity according to your usage scenario.
  • Quality Assurance and After-sales Service: WattCycle batteries offer 5-10 years of float and standby use with no maintenance required. With a single installation, you can have your system or application up and running quickly. All WattCycle lithium batteries come with after-sales quality assurance. For any questions or quality issues, please contact our support team. We are committed to providing you with satisfactory after-sales service.

Q1: Do I need to charge it when I receive it?

A1:
The default of the new factory battery is [ sleep state ],the first 3 times need to befully charged,discharged and then fully charged,and then discharged ... to fully activate the battery capacity.

Q2: How can l charge it?

A2:
1) Please keep the battery pack 30%-60% of the power storage, and charge the battery once every 3 months.

2) Please select the LiFePO4 charger with a rated voltage of 14.6V according to the parameters specified on the battery nameplate to charge the battery.

Q3: What is the recommended fully charge voltage and current?

A3:
The recommended fully charge voltage is 14.2-14.6V. And the current is under 12A.

Q4: What are the precautions when I use the battery?

A4:
The battery is classified as a flammable and explosive item. Please use it with caution.
When you are using it, no short circuit, no crush, no disassemble or no incinerate.
And please avoid the mechanical impact.

Q5: What is prohibited when l am using the battery?

A5:
1) It is forbidden to make the positive and negative poles of the battery pack shortcircuit.
2) It is forbidden to charge in the summer sun exposure or high temperature.
3) Prohibit the battery pack from touching any liquid,avoid rain/moisture.
4) Prohibit the dismantling and modification of the battery configuration.
5) Prohibit flammable and explosive,high temperature,high humidity,sun exposure.
Kind Reminding:
Before vibration use,please match the battery specifications you need to useaccording to the voltage,current,capacity,power and other parameters on thelithium battery nameplate.

Q6: What is the Installation of the battery?

A6:
Before installation and use, please check the relevant waterproof, shockproof, short circuit prevention, puncture prevention, heat prevention, and prevent the plug and socket from touching the bad ignition and damage the battery.


LiFePO4 batteries are used in parallel: Because the battery is not fully charged before it leaves the factory, please fully charge the battery before parallel installation, and test the voltage of each battery. It is recommended to keep the voltage difference of each battery within 30mv in order to extend the battery life.


LiFePO4 batteries are used in series: the lithium battery maximum series is 4*12V=48V,for the sake of balance.
Before the series, batteries need to be charged firstly, and place the 4 groups of batteries in parallel for more than 12H.Before use:
If you find that there is battery deformation or damage, smelly, smoke or abnormal heat, swelling, water ingress and other abnormal conditions ,please do not use, contact the dealer in time to deal with it.
Q7: Can the Wattcycle battery support the series or/and parallel connections?

A7: Yes!
WattCycle LiFePO4 Battery can support series or/and parallel connections, with a maximum configuration of 4S4P.

By combining series and parallel connections, you can achieve the desired voltage and capacity.
For example, four 3.2V 8Ah batteries connected in series form 12.8V, and then connecting two such series strings in parallel results in a system with 12.8V 32Ah.

By combining series and parallel connections, you can design battery packs that meet specific application requirements, providing greater flexibility and scalability.

Q8: How can I increase the voltage?

A8:
Series connection increases the voltage to meet the voltage requirements of the device or system.

Series Connection:
Connecting the positive terminal of one battery to the negative terminal of another battery to increase the voltage.
The voltages of each battery are added together, while the capacity (ampere-hours, Ah) remains the same.

For example, connecting four 3.2V batteries in series results in a total voltage of 12.8V.

Q9: How can I increase the capacity?

A9:
Parallel connection increases the capacity to extend the runtime and enhance the overall current supply capability.

Parallel Connection:
Connecting the positive terminals together and the negative terminals together to increase the capacity (Ah).
The capacities of each battery are added together, while the voltage remains the same.

For example, connecting two 3.2V 8Ah batteries in parallel results in a total capacity of 3.2V 16Ah.

Q10: What are the necessary steps for the connection?

A10:
There are two steps necessary in order to reduce the voltage difference between batteries, and through these, the battery system can perform the best of it in series or/and in parallel.

Step1: Fully charge your batteries.
Step2: Connect your batteries one by one in parallel, and leave them together fro 12-24hrs.

And then, you can connect your batteries in series or/and parallel.

Q11: What can l use it for?

A11:
1)Fish finding
2) Wireless Lawn Movers, Vacuum Cleaner & Washing Machine
3) Portable Video Camera & Portable Personal Computer
4) Car Audio System
5) Light Equipment
6) Emergency Lighting Equipment
7) Fire Alarm & Security Systems
