How to choose a suitable 18650 battery?

Question

Batteries

1. Such batteries come with and without “ peeps ”. I need it without, because the ones that I had with peeps do not fit into the power bank. What is the correct name in English for "flat plus" for 18650 batteries?
2. If I understand correctly, then 18650s come with built-in electronics (PCB) for short circuit protection, overcharging, etc. Is it true that if there is no pip, then there is no electronics? But is the opposite true?
3. If the battery is with a pip and with electronics, is it possible to safely pick this pip and get a 18650 with a flat plus and no PCB?

Answer 1

Sanyo, Sony, Panasonic. There are no other 18650 batteries. Those. Of course, you can buy something similar in the same sizes, but it's better to spend this money on charity - mysku.ru/blog/others/9018.html Review of 2012, but nothing has changed during this time.
1. Not called at all. They did not climb into the power bank because of the protection board, and not because of the beep. Only Sony 2600 has a flat plus.
2. No. Pipka is just a contact.
3. The protection board can be removed. But it's better to buy normal batteries without protection. There are only 4 models.
