Frequently Asked Questions

Are your lithium batteries equipped with a BMS?
Yes, all our batteries include an integrated IC BMS (Battery Management System). This provides stable performance and protects the battery from short circuits, overcharging, over-discharging, and overcurrent.
What is the expected lifespan of this battery pack?
The battery is designed for approximately 2000 deep cycles. Under normal usage conditions, it typically lasts 2-3 years before the capacity begins to diminish to around 75-80%.
How should I maintain the battery when not in use?
Store the battery in a clean, dry, ventilated, and dark environment. It should be stored after a full charge and recharged every 3 to 6 months to maintain health.
Do your batteries come with a charger?
Yes, our battery packs are supplied with a compatible charger. We offer both normal and fast charging options depending on your specific requirements.
What is the advantage of Li-ion over Lead-acid batteries?
Li-ion batteries offer a significantly longer cycle life, are much lighter and smaller, have no memory effect, and are more environmentally friendly and non-toxic compared to lead-acid batteries.
Do you provide customization (OEM/ODM) services?
Yes, we are a professional manufacturer specializing in high-quality lithium batteries. We can produce custom battery packs based on specific customer requirements and designs.
