When a drone manufacturer asks for a battery, the first specifications are often something like: “We need 6S, 10,000mAh, 30C.” It sounds straightforward. But there is usually a second conversation after that. What does the drone actually weigh? How much payload does it carry? What current...

Short answer: For most cordless power tools, high-discharge lithium-ion batteries using 18650 or 21700 cells are currently the best choice because they offer a strong balance between power output, weight, runtime, and cost. For manufacturers and distributors, the right battery chemistry depends...

Do batteries weigh more when charged? Yes, a charged battery technically weighs slightly more than a discharged battery because stored energy has mass. However, the weight difference is extremely small—far below what normal scales can detect. In real applications, battery weight is mainly...

A lithium battery usually does not fail overnight. Most customers notice the problem slowly: A power tool that used to work for hours suddenly needs charging more often. An electric vehicle loses range. A solar storage system cannot provide the same backup time as before. When this happens...

When companies develop energy storage products, choosing battery cells is usually one of the first decisions. But after years of working with battery projects, many manufacturers realize that the cell itself is only part of the solution. A reliable battery pack needs more than high capacity...

When people evaluate a drone, they often look at the camera quality, flight controller, communication range, or payload capability. The battery usually stays behind the scenes. But for commercial UAV manufacturers, the battery is one of the parts that can directly affect the product...

When drone company develops a new UAV, battery safety is often discussed after performance. The team may first focus on: “How long can it fly?” “How much payload can it carry?” “How fast can it operate?” But after the drone enters real-world use, another question becomes much more...

How to Choose the Right Voltage and Capacity for a UAV Battery? When drone manufacturer starts designing a new UAV, battery selection is usually not as simple as choosing the largest capacity available. A common question from buyers is: “Can we just use a bigger battery to get longer flight...

A common question from drone users is: “I have a 3.7V LiPo battery. Can I just buy another 3.7V battery and plug it in?” It sounds reasonable, but the answer is usually no. A few times we have seen customers choose a replacement battery based only on voltage. The battery was 3.7V, the capacity...
