Does a lithium battery pack need a protection board
Lithium Battery Pack
$begingroup$ Some of this is correct but the answer fails on many levels. For 1 there is a reason lithium cells require a BMS to be used safely. The biggest glaring issue with this answer is it fails to mention that not having a BMS on any additional batteries running in paraellel will fail to keep the non BMS batteries in balance.
Why do cordless tool batteries have a circuit board connected?
$begingroup$ It should be noted that a lot of the more modern & high power offerings don''t do the over-discharge and over-charge protection within the battery (if you inspect the board carefully you will be able to see the main power terminals are linked directly to the cells). The pack does manage cell balance though.
Lithium-Ion Battery Circuitry Is Simple

Do I need a BMS for Li-ion batteries connected only in parallel?
You do not need a full-blown BMS. Your stated charge/discharge currents are way below 18650 ratings (so you can get away without thermal sensor) and parallel cells do not need balancing. But you do need a protection circuit. As a minimum a combination of discharge cut-off and discharge current limit.

Battery Safety 101: Anatomy
Does your battery have protection circuitry? 18650 batteries sold in the US are required to have CID and PTC protection. However most cells for vaporizers are sold without PCB''s. This is because the PCB will limit the amp discharge of your battery to 6A, when vaporizers need 10A - 30A.
Battery management system
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as SoH, and SoC), [1] calculating secondary data, reporting that data, controlling its …
Deep Analysis of the principle of lithium battery protection board
The reason why the lithium battery (rechargeable type) needs protection is determined by its own characteristics. Because the material of the lithium battery itself determines that it cannot be over-charged, over-discharged, over-current, short-circuited, and ultra-high temperature charge and discharge, so lithium battery or battery pack will …
