The Process Flow & Duration Estimation
From Design To Sale, Are Leadmax Battery Solutions Safe?
ISO9001 is the most fundamental guarantee
Safety in the design phase: Leadmax Battery only uses grade A quality lithium battery cells, mostly designed for EV systems. The engineering team has more than 12 years of experience in the field of lithium-ion batteries. As part of the design phase, all safety points will be fully taken into consideration, such as strengthening the battery’s internal structure, choosing a better BMS, and determining the appropriate IP grade etc.
Safety in the delivery phase: All of Leadmax Battery’s solutions are compliant with UN38.3. These lithium batteries can be shipped worldwide. Moreover, Bonnen Battery can also provide global delivery services at a reasonable cost. Because we have cooperated with a lithium battery forwarder together.
Cooperation With Leading Lithium Battery Cell Manufacturers
Leadmax had built a reliable distribution channel to source lithium battery cells from Tier 1 battery cell manufacturers in the world. Each project uses grade A cells from CATL, GOTION, EVE, Ganfeng, FARASIS, LISHENG, etc.
Leadmax battery cells can always able to be tracked, they have been properly aged, and they are grouped before being used in your project. We booked the cell early each quarter to guarantee customer deliveries and minimize any sudden cost impact from the market.
Standard products are produced within 15-20 days and shipped immediately via sea or air. Customized products are produced within 30-35 days. Sea shipping usually takes 28-35 days.
An extensive product line, fully traceable production processes, an average warranty of over 10 years, stable cell resources from CATL, BYD, Gotion, and EVE, and support for production process visualization.
For orders below $10,000 USD, we accept 100% prepayment via T/T. For larger orders, we require a 50% prepayment. Once production is complete, we provide videos and images or conduct live video inspections, and the balance is paid before shipping.
We use cells from leading domestic brands like CATL, BYD, EVE, and Gotion. If you have a specific cell brand in mind, we can accommodate your request.
If you encounter a problem, please contact us via email at [email protected] to request a warranty. Describe the issue you’re facing, and we’ll reply within 12 hours and assign a dedicated customer service representative to assist you. Further responses will usually come within minutes for quick communication.
Typically, the warranty period is determined through rigorous testing. However, custom products are designed and assembled to client specifications, making it challenging to conduct comprehensive short-term testing. In most cases, we provide a 5-10 year warranty, depending on the specific application scenario, which will be clarified during communication
Yes, to meet customs and various national requirements, our standard products are certified with CE, MSDS, and UN38.3. Our cells generally have RoHS, UL1973, and IEC62619 certifications, with digital certificates available.
