▍ Do you also do OEM or ODM products for customers?
Yes, we could do OEM and ODM services for our customers around the world. You could forward your details demands to us via email, WhatsApp, or WeChat.
▍ What color do you have for your battery chargers?
We have silvery color which customers ordered most, and Blue, Red, Black, or other colors can be produced as per your request as well. Please kindly provide the Pantone colors you need, then we will check and confirm for you immediately.
▍ How do you make it to meet IP65 waterproof?
We do full glue inside the charger, and the LED’s to be glued from the inside properly. Put the rubber gasket between the edges of the side plates and the metal case. Put epoxy glue on all external open screws. The fan outside also has IP65 waterproof certificate.
▍ Did the charger has an interlock function?
If the charger is On board charger model, it has the interlock function. When the batteries are being charged (charger is being used with AC on), the electric vehicle motor, headlight, etc. cannot be used and the electric vehicle cannot move too. It is done by using the signal from the interlock.
▍ If your battery charger can work for both lead acid and lithium batteries at the same time?
A battery charger can work for 1 type of battery after the factory setting. If you have both lead acid and lithium batteries, we’d like to suggest taking both lead-acid chargers and lithium chargers. Please contact our expert to advise your battery type and voltage, then we will provide the suitable one for you very soon.
▍ Why can’t lead-acid batteries and lithium batteries of the same voltage use the same kind of charger, such as 57.6V lead-acid batteries and 57.6V ternary lithium batteries sharing a charger？
Specifically, when the charger charges a 57.6V lithium battery, and reaches the constant voltage stage of 57.6V and the current reaches 2A, the charger cut off automatically; When the charger charges a 57.6V lead-acid battery and reaches the constant voltage stage of 57.6V and the current reaches 5A, the charger switches to the float charge stage of 55.2V. If use the charger which designed for lithium batteries to charge lead acid batteries , this way will reduce the life of lead acid batteries due to the lack of floating charging 55.2v; If use the charger which designed for lead acid batteries to charge lithium batteries , this way will cause the lithium battery to not be fully charged due to the process of floating charging 55.2v. Therefore, we recommend that lead-acid batteries and lithium batteries be charged by their specially designed chargers respectively.
▍ Could you explain the Precharge function?
Precharging is to protect the life of the battery. When the battery voltage is lower, the internal resistance of the battery is greater (the heat is more serious), and the current it can withstand is smaller. Precharging is to reduce the current when the battery voltage is low to reduce heat generation to protect the battery.
▍ How many colors does the LED light(Indicator) come with? And what is the meaning of each color?
We have the LED indicator with tri colors, yellow, red and green color.
Steady Red Indicator：Charging
Steady Yellow Indicator：Almost Full
Steady Green Indicator：Full
Red Indicator Flashing：Charger failure
1. Initially just powered on – 1S period flashes
2. The battery is reversed – 0.5S cycle flashes
3. Output overcurrent -1S period flickering
4. High battery voltage – 2S period flashing
5. Low battery voltage – 3S period flashing
6. Output voltage high – 4S period flashes
7. Battery failure -5S period flashes
▍ What is the operating & storage temperature range for this charger?
The operating temperature -20℃ ~ 50℃, storage temperature -40℃ ~ 80℃.
▍ Can you make with universal input voltage 100 – 240Vac if required?
Yes, our chargers support 100-240VAC and 50/60Hz. No matter your market is European, South American, Asia or others, we are all supported.

Confirme las especificaciones básicas (tensión de salida/corriente de salida) del cargador que necesita. Podemos proporcionarle la hoja de datos de especificaciones relacionadas por adelantado. Por favor, encuentre la COTIZACIÓN RÁPIDA en la parte inferior y enviar la investigación para la hoja de datos y más detalles.
Nuestro cargador soporta múltiples marcas y tipos de baterías, pero para asegurar la mejor compatibilidad, por favor confirme si su tipo de batería es compatible antes de comprar. Es la batería de iones de litio, LiFePo4 batería, batería de plomo u otros tipos?
Algunos de los cargadores de nuestra empresa admiten voltaje de entrada de banda ancha (como 100~240V) y pueden utilizarse en todo el mundo. Sin embargo, algunos cargadores sólo soportan un rango de voltaje específico, como algunos cargadores sólo soportan 100-120V de voltaje AC, y algunos cargadores sólo soportan 180-240V de voltaje AC. Por favor, confirme su voltaje de CA antes de comprar.
Apoyamos el servicio de muestras. Puede comprar muestras para probarlas primero. Una vez probadas las muestras, puede comprar productos a granel. La cantidad mínima de pedido de productos a granel es superior a 10 unidades.
Nuestras muestras de cargadores suelen tardar 7-8 días laborables. El tiempo de producción de productos a granel varía según la cantidad. Tarda 10-15 días laborables para menos de 100 piezas, 12-16 días laborables para menos de 500 piezas, 14-18 días laborables para menos de 1000 piezas, y 20-25 días laborables para más de 2000 piezas.
Por favor, envíenos las especificaciones del cargador (tensión de salida y corriente) que necesita o la información de la batería de aplicación (como el tipo de batería y la capacidad de la batería) y la quanity de cargadores que necesita, y le enviaremos por correo electrónico una mejor cotización. O puede ir a la parte izquierda de la página del producto para enviar un mensaje a través de WhatsApp para la cita, y le responderemos inmediatamente.
