When walking in the woods, or camping, carrying a power bank may be a good idea to ensure you keep your memories flowing. The best power banks are made with 18650 batteries. If you cannot buy one, get two batteries and a BMS and create your own. 

RC toys 

We have all had experience with electric powered toys. The best of these are powered by 18650 battery packs.

Some laptops still use the 18650s. Though not very many today, they are still serving as good as lithium-ion ones.  

How to avoid buying fake 18650 batteries 

The 18650 industry has been most hit with fakes. They are everywhere, and you cannot assume every product you meet is good. 

The biggest problem is discerning the fakes. How do you tell what you have is original and of high quality? Consider the following:

Spot weld marks

The batteries are supposed to be smooth on the positive and negative terminals. But if you buy one and discover spot weld marks, they are fakes. Sometimes, marks are indicating some sort of grinding to remove the spot welds. 

Fake wrappers

Anyone can put a wrapper on any battery. As long as they have minimal intelligence, it is something they can do. For instance, some companies take cheap batteries and fit with fake branded wrappers from companies like Sony or Panasonic. 

The problem is telling whether the battery is fake or not. Many consumers don’t have the equipment to measure charge and capacity. The fake battery may appear to hold some charge just like the originals. 

Your instincts should tell you something is wrong.

Fake dealers

The original batteries are only found with manufacturers and selected dealers. Today, many Chinese websites are selling printed wrappers, which can be used to make fakes. It is therefore important to consider where the batteries are coming from. 

Price 

Fake 18650s are quite cheap. You can get them for a slow as $1. But original once go for up to $10. With this, you can easily measure the quality you are getting. 

How to use 18650 batteries properly

Using 18650 batteries may seem basic. But there is more to it than meets the eye. Here are the best tips to help use them correctly. 

-Research. Especially with DIY battery packs, you need the proper knowledge. Otherwise, you may cause more harm than good. Explosions and fires happen because of neglecting rules, however basic. 

-Do not overcharge; it destroys the cells.

-Do not over-discharge, or over-drain the batteries. The same effect as overcharging can occur. 

-Use the right pack for the right gadget. Before making a battery pack, know how much power you need. 

-Use the correct charger.

-Get the right BMS for DIY battery packs. 

-Buy original batteries
