Using A-grade battery cells:

Why does Delong dare to offer a 10-year warranty period? This is because all our lithium batteries use A-grade lithium iron phosphate cells from well-known manufacturers, such as BYD. Lithium iron phosphate is known for its stability and can provide you with 100% safety.

Low self-discharge rate:

The power consumption of lithium iron phosphate batteries is slow, and even if you don’t use it often and let it sit idle in the corner, it can maintain as much energy as possible.

Maintenance-Free:

This advantage should be clear to you even if it’s not explicitly stated. Lithium batteries that don’t require regular watering truly reduce a lot of hassle and save much time.

Waterproof Battery:

The housing of the 12V 40Ah lithium battery is made of ABS+PC material, which provides an IP55 level of waterproofing capability.

Bluetooth & Heating

If you wish to further free up your hands and feet, you can also add Bluetooth capability. An app on your phone allows you to monitor the battery’s working status in real time. If you find yourself in a cold area, you can opt for the self-heating feature as well. This self-heating function raises the surrounding temperature to a range where the battery can deliver its optimal performance.

Custom Battery Services

In addition to these additional features, our customization service can tailor the voltage and capacity specifically for your device. From 6V, 12V, 24V, 36V, 48V, 72V to 96V — these are all parameters with which our engineers are highly familiar.
