▍ 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.

Please confirm the basic specifications (output voltage/output current) of charger do you need . We can provide the related specifications data sheet for you in advanced. Please find the QUICK QUOTATION at the bottom and send inquiry for data sheet and more details.
Our charger supports multiple brands and types of batteries, but to ensure the best compatibility, please confirm whether your battery type is supported before purchasing. Is it Lithium ion battery, LiFePo4 battery,Lead Acid battery or other types?
Some of our company’s chargers support wide-band input voltage (such as 100~240V) and can be used worldwide. However, some chargers may only support a specific voltage range, such as some chargers only support 100-120V AC voltage, and some chargers only support 180-240V AC voltage. Please confirm your AC voltage before purchasing.
We support sample service. You can buy samples for testing first. After the samples are tested, you can buy bulk goods. The minimum order quantity for bulk goods is more than 10units.
Our charger samples are usually 7-8 working days. The production time of bulk goods varies according to the quantity. It takes 10-15 working days for less than 100 pieces, 12-16 working days for less than 500 pieces, 14-18 working days for less than 1000 pieces, and 20-25 working days for more than 2000 pieces.
Please send us the charger specifications (output voltage and current) you need or the application battery information (such as battery type and battery capacity) and the quanity of chargers you need, and we will email you a best quotation. Or you can go to the left side of the product page to send a message via WhatsApp for quotation, and we will reply you immediately.
