Do you provide warranty, if yes, how long?
Yes, we offer a standard three-year warranty for all our battery packs. Buyers can request an extended warranty period before placing orders. Please inquire about the 'Terms and Conditions of the Warranty' beforehand.

What are the application fields of your battery packs?
We supply Li-ion battery packs for a wide range of applications: electric vehicles (4-wheeled and 3-wheeled trucks, sweepers, cars, forklifts, golf carts, sightseeing buses, monorails, ATVs, UTVs, tricycles, motorcycles, toy cars, etc.), solar energy power storage, electric equipment (floor scrubbers, lifting platforms, small excavators, tractors, pallet stackers, grass cutters, small cranes, garbage tanks, arm gates, etc.), outdoor portable power supplies, portable power for construction equipment, streetlight power packs, boat power packs, camper power packs, and more.
As a customization-oriented Li-ion battery manufacturer, we welcome customizations for various applications.

Can your batteries be used in series?
Most of our batteries are not designed to be used separately. However, we offer small 12V battery modules that can be used in series or parallel, ideal for replacing old lead-acid batteries. Please inquire in advance for specifics.

Do your batteries have a thermal management system?
Yes, most of our batteries are equipped with a thermal management system controlled by the BMS (Battery Management System). This system prevents battery use under extreme temperatures. Please inquire for more details.

Do you provide OEM or ODM.
Yes.

How many years will your battery last?
Lithium Iron Phosphate (LiFePO4) batteries can be cycled 2000 to 5000 times. If cycled daily at 80% DoD (Depth of Discharge), you can expect a lifespan of 5-10 years.

How do I install your batteries?
All our batteries come with free ring terminals for easy connection to your inverter, cart, or busbar system.

Can I leave your batteries outside?
No. Our batteries are not rated for marine or weatherproof conditions. Exposure to the sun or rain can cause damage, which is not covered under the warranty.
