Frequently Asked Questions

The two battery models have no differences in performance, specifications, or capacity. The only difference is that the ECE R10 version has ECE R10 certification on its case, making it better suited for RV use.

  • If you intend to use the battery for marine or solar applications, you can opt for the standard version, which is lower in price.
  • If you plan to use the battery in an RV, the ECE R10 version is the better choice.

Yes! LiFePO4 batteries are among the most stable lithium batteries on the market. WattCycle LiFePO4 batteries use high-quality Grade-A LiFePO4 cells and are equipped with an integrated battery management system (BMS) that provides protection against overload, overvoltage, extreme temperatures (including deep discharge protection), and much more. All WattCycle batteries undergo rigorous testing before shipment and have certifications such as CE, RoHS, and UN38.3. Buy with confidence now!

A LiFePO4 12V 628Ah Ultra lithium battery has a total usable energy of 8.038 Wh, calculated by multiplying the voltage (12.8 V) by the ampere-hours (628 Ah).

The LiFePO4 12V 628Ah Ultra lithium battery is equipped with Bluetooth 5.0. Using the WattCycle app, you can monitor the following data (for reference only; actual data may vary depending on the app version): status, temperature, voltage, current, and individual cell voltages.You can also control the charging and discharging processes directly via the app.If you prefer not to install an app, you can alternatively use a 500A battery monitor to track the battery status.

The operating time of the battery depends on several factors, including battery capacity, connected load, and battery condition. For example, a new battery performs better than a used one, as capacity gradually decreases slightly over the number of charge cycles.However, the runtime can be estimated using a simple formula:

Battery runtime (hours) = Battery capacity (Wh) / Total device power consumption (W)

For example, if you use a 12V 628Ah Ultra LiFePO4 lithium battery and connect a 50W lamp and a 50W speaker, the battery runtime would be:

8,038.4 Wh / (50 W + 50 W) = 80.38 hours

This simple calculation helps you estimate runtime under different load conditions.

It is not recommended. However, if no suitable LiFePO4 charger is available temporarily, a standard charger may be used for charging.

WattCycle recommends using a 12V 125A LiFePO4 charger for optimal performance and battery life.

The charging time depends on the specifications of your PV system, including the size of your solar panels and the capacity of your solar charge controller.

For example, if the 12V 628Ah Ultra LiFePO4 battery covers your daily energy consumption and you have around 4.5 hours of effective sunlight per day, you would need to generate approximately 8,038.4 Wh of energy.To achieve this, you would require at least 1,786.31 W of solar panels, so a 2,000 W system is recommended. This could consist of four 500 W panels or five 400 W panels.For a 2,000 W PV system, the required charging current is approximately 167 A. However, most MPPT solar charge controllers available on the market are typically rated at around 100 A, so it is recommended to use two 100 A MPPT controllers.

Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore All WattCycle LiFePO4 12V lithium batteries support different configurations, including series, parallel, and series-parallel connections. You can connect up to 4 batteries in parallel and 4 in series, meaning a total of 16 units of the 12V 628Ah Ultra LiFePO4 battery can be combined to achieve an energy storage capacity of up to 128.61 kWh.

It is important to always use identical battery models with the same voltage, and ensure that batteries are not older than 6 months when combining them in a system.magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Two 12V 314Ah Mini LiFePO4 batteries connected in parallel and one 12V 628Ah Ultra LiFePO4 battery provide the same total capacity. However, using a single battery system generally offers better consistency and more stable operation. In addition, it requires less wiring and takes up less installation space.

Not recommended. There are four key rules for connecting WattCycle batteries in series or parallel:

  1. Same brand
  2. Same voltage
  3. Same capacity (Ah rating)
  4. Manufacturing/purchase date not older than 6 months

Mixing different models may lead to imbalance and affect system performance and safety.

Customers praised this 628Ah lithium battery for its "huge capacity" and "excellent build quality" with robust cell protection. The Bluetooth app works well, and it "feeds my 2000W inverter to perfection." Customer support is outstanding. Minor concerns include the Bluetooth connector being short and charging limited to 97%.

Excellent battery quality and outstanding customer support

I purchased a WattCycle 12V 628Ah battery for my motorhome. Although the battery arrived with some damage caused during shipping, my overall experience with WattCycle has been very positive.

From the very beginning, their customer support responded quickly, kept me informed throughout the process, and provided a satisfactory solution. What I appreciated most was that they focused on making sure the battery itself was in perfect working condition rather than simply dismissing the issue.

They explicitly authorized me to open the battery to verify that there was no internal damage and confirmed that doing so would not affect the warranty. They also assured me that the external damage caused during shipping would not compromise the warranty coverage if I ever needed to make a warranty claim in the future.

After opening the battery, I confirmed that the impact had not affected any of the cells. I was genuinely impressed by the excellent build quality. The cells are protected by a very robust metal frame and are positioned well away from the outer casing, providing a level of protection that is noticeably better than in many other LiFePO₄ batteries I have seen.

After completing the inspection, I tested the battery and everything worked perfectly. Charging and discharging operate normally, and the cell voltages are exceptionally well balanced.

Overall, I received not only a battery that inspires confidence because of its outstanding construction, but also excellent after-sales support. It is reassuring to know that, if something goes wrong, the company stands behind its products. Based on my experience, I would definitely buy from WattCycle again.

I'm very satisfied

I'm very satisfied, but i think that the Bms could be a little bit biger. And i wonder why i can only loade it up to 97 percent.
Otherwise im very happy with it.

Dear customer, thank you for your question. The 12V 628Ah case is steel/metal.

vad är skilnaden med ECE R10-version

WattCycle-Europe

Hej! Tack för din fråga. När det gäller batteriets tekniska specifikationer och prestanda finns det ingen teknisk skillnad mellan de två versionerna. Den huvudsakliga skillnaden ligger i ECE R10-certifieringen och den tillhörande märkningen på batterihöljet. ECE R10-versionen har den aktuella certifieringsmärkningen, medan versionen utan ECE R10 saknar denna.
Om batteriet främst ska användas i en båt eller ett solenergisystem, och ECE R10-certifiering inte krävs för din tillämpning, kan du även välja vår version på 12 V och 628 Ah utan ECE R10.
Om installationen i din husbil uttryckligen kräver ECE R10-dokumentation, vänligen välj den ECE R10-certifierade versionen.

Que diferencia hay en una batería de tener versión ECE R 10 a no tenerla?

WattCycle-Europe

Estimado cliente, gracias por su consulta.
Nuestra batería de 12 V y 628 Ah cuenta con la certificación ECE R10, lo que significa que ha superado las pruebas de compatibilidad electromagnética de la UE para vehículos.
La única diferencia es que una versión no lleva la marca ECE R10 en la superficie de la batería, mientras que la otra sí.
Si necesita asegurar el vehículo o registrarlo como vehículo de uso especial, será obligatorio que la batería cuente con la certificación ECE R10; en este caso, la versión con ECE R10 es la opción más adecuada.
Sin embargo, si la batería está destinada a su uso en una embarcación o en un entorno doméstico, la versión sin la marca ECE R10 es perfectamente válida.
No dude en ponerse en contacto con nosotros si tiene alguna otra pregunta.

minua kiinnostas itselämpiävä akku kun joudun mökillä pakkasella latamaan. mielummin joku yli 600ah

WattCycle-Europe

Hyvä asiakas, kiitos kysymyksestäsi. Pahoittelemme, ettei 12 V 628 Ah -akussa ole itselämmitystoimintoa. Kylminä talvina itselämmitystoiminnon käyttöön suositellaan 12 V 314 Ah:n itselämmittävää akkua (https://eu.wattcycle.com/products/12v-314ah-mini-heat-battery-with-bluetooth). Ole hyvä ja kytke rinnakkain kaksi 12 V 314 Ah:n itselämmittävää akkua muodostaaksesi yli 600 Ah:n järjestelmän. Ota rohkeasti yhteyttä, jos sinulla on lisäkysymyksiä. // Dear customer, thanks for your question. Sorry that the 12V 628Ah doesn't have the self-heating function. For the self-heating function in cold winters, the 12V 314Ah self-heating battery is recommended (https://eu.wattcycle.com/products/12v-314ah-mini-heat-battery-with-bluetooth). Kindly parallel two 12V 314Ah self-heating batteries to form a system with more than 600Ah. Please feel free to contact us with any further questions.

Qué es la versión ECE R10

WattCycle-Europe

Estimado cliente:

Gracias por su pregunta.

ECE R10 son las siglas del Reglamento n.º 10 de la Comisión Económica para Europa de las Naciones Unidas. Es la principal norma técnica que rige la compatibilidad electromagnética (CEM) para vehículos y los componentes eléctricos y electrónicos instalados en ellos.

La versión ECE R10 significa que esta batería cuenta con la certificación ECE R10, la mejor opción para su uso en autocaravanas, especialmente si desea contratar un seguro para su vehículo.

Para cualquier otra consulta, no dude en contactarnos.

Saludos cordiales,

——————————————————————————————

Dear Customer,

Thanks for your question.

ECE R10 is shorthand for United Nations Economic Commission for Europe Regulation No. 10. It is the primary technical standard governing electromagnetic compatibility (EMC) for vehicles and the electrical and electronic components installed in them.

The ECE R10 version means this battery is ECE R10 certified, which is the best choice for use in the motorhome, especially when you want to buy insurance for your motorhome.

For any further questions, please feel free to contact us.
Best regards,
