A: For the upgraded version of the lithium battery, we use lithium iron phosphate (LifePO4) batteries, which are more stable, safer, and have a very constant discharge voltage, allowing the battery to provide more power.

A: For customized products, the three-element lithium battery group warranty is for one year; the Lithium Iron Phosphate battery group warranty is for two years; the lead-acid converted lithium battery warranty is for two years; the start-stop Lithium Iron Phosphate battery warranty is for 4 years; for other specific products, please refer to the product manual.

A: The voltage of the three-element 12V battery is 11.1V, while that of the lithium iron phosphate 12V battery is 12.8V. As different electrical appliances have different voltage ranges, such as electric vehicles, the higher the voltage, the faster and more powerful the vehicle runs; when the voltage is low, it runs slowly, but it can still be used. Therefore, 12V generally refers to the voltage range between 10V and 14V, and this applies to 24V as well.

A: Lithium batteries should be charged at least once every three months for proper storage. Products damaged due to failure to follow proper storage procedures are not covered under warranty. Please make sure to recharge your batteries in a timely manner.

A: Yes, we welcome sample orders for testing and quality checking.
