The volume to capacity ratio is the capacity divided by the battery volume, and the mass to capacity ratio is the capacity divided by the mass. Extending from here, we can convert the cost of batteries into unit capacity, which is to discuss the price from the perspective of battery charging and dis...

How to calculate how many strings, parallel connections, and battery cells are needed for a set of lithium batteries?Answer 1: It's very simple. Series connection increases voltage, parallel connection increases capacity. The standard voltage for ternary lithium is 3.7V, full charge is 4.2V, and...

For those with a key switch, first open it, then lift out the battery box, under the foot pedal, under the back seat. For those with a bicycle style, first open the saddle and unplug the wires. If you still want to remove it, remove the screws on the battery box and open the cover. Be careful not to...

With the upgrading and upgrading of electric vehicle battery technology, the development and application of lithium batteries continue to rise. However, it is only a continuous increase, and due to the safety performance and cost-effectiveness of lithium batteries, there is still a considerable dist...

Firstly, you need to prepare the following:1. Battery;2. Relay, it is recommended to use headlight relay. If not, the start relay is also acceptable, and the horn relay is too easy to break;3. High voltage package, which is the ignition coil;4. Several wires., 1-2 capacitors.Once ready, you can conn...

The 18650 lithium-ion battery is a cylindrical battery, more accurately called a battery cell. 18650 is the size specification of the battery cell. 18 represents the diameter of the battery cell of 18MM, 65 represents the length (height) of 65MM, and 0 represents the cylindrical battery cell. Due to...

The application of lithium batteries in the field of electric vehicles has a wide coverage, and the number of discarded lithium batteries is also very astonishing. According to statistics, about hundreds of millions of discarded lithium batteries are scrapped every year, which is a serious waste of...

"After removing the toy car, the remote control can still be used!" The advertisement for Nanfu Battery explains in a simple and understandable way what battery cascading utilization is. When the capacity of the power battery decays to 80%, it is not suitable to continue serving on the veh...
