Can we make our own lithium battery pack?
We can make our own lithium battery packs, but there is a certain danger of making their own lithium battery packs, the cost of lithium batteries is more expensive than the cost of lead-acid batteries, their own production will be very cheap, in the homemade when we need to take into account the knowledge of homemade battery packs, product quality, product quality, failure to cope with the method, and there are a lot of uncertainty about the safety factors and other issues need to be considered.
What are the dangers of homemade lithium battery packs?
(1) The quality of the battery pack, the brand of the battery cell, the battery pack’s warranty is qualified, the date of production and the battery’s old and new.
(2) Battery pack short circuit
Homemade battery packs may lack of specialized knowledge, if not properly connected or using poor quality materials, they can not grasp the amount of battery packs required, will lead to high temperature phenomenon of the battery, it is very likely that a short circuit or explosion. Battery packs in improper use or failure will produce leakage phenomenon, a serious threat to our own health problems. Use the correct charging equipment to avoid short circuit caused by charging errors.
(3) Battery assembly problems
Battery pack assembly is very important, the assembly of the battery pack has two ways a kind of welding, there is also a kind of screws to fix, the battery assembly requires a certain degree of security, firmness, assembly of battery packs need welding technology, welding through the heating to connect the metal plate and the battery, the temperature is too high will be lost to the metal plate, the requirements of welding technology is very strict, these need professional equipment and technology to ensure the battery pack’s Use performance. Connect with each cell, put on the screws, use the flange nut, screw tight, prevent the nut from detaching, it can play a role in fixing the battery pack.
BMS reliability
If you have researched how to make your own battery pack, then you should also have heard of battery monitoring systems, BMS is an important part of lithium batteries, they can be monitored to ensure that the battery caused to run, measuring temperature, voltage, load, resistance and current, and so on. If something goes wrong, the BMS will disconnect the battery to ensure safety, without a reliable BMS, you can’t find out if your battery is working properly.
No protection
Battery manufacturers make their batteries with all the safety features and tests, this kind of specialization is hard to do on your own, if the battery malfunctions, it’s hard to fix it on your own, homemade battery packs lack protections, so your battery pack will be at a higher risk. The equipment powered may be damaged or not function properly.
Environmental issues
Assembling lithium batteries should consider the environment in which they are placed, too low or too high a temperature will affect the performance of the battery.
Summarize
There are many uncertainties to consider in the homemade lithium battery packs, homemade battery packs require specialized technology and equipment, not a professional operation may be difficult and cause damage to the battery pack.
Although lithium battery pack with its high energy, small size, convenient way, high storage power and other advantages to change our lives, but homemade battery pack in terms of safety, quality assurance, as well as technical requirements and other aspects of the danger, so do not recommend their own homemade battery pack, if you need to replace the battery, it is recommended that you buy a battery pack from the regular channels, certified brand batteries, to ensure that the use of the safety of the battery.
