Couple of things to be aware of first.
In particular if they are salvaged or mixed age or batch cells. Capacity or near capacity matched when it comes to series parallel batteries is safer and will yield better results so if you have a method of testing this then
If not take as much care to try and match them same brand age etc, some of the so called capacities out there just are not true.
With your current draw of only one amp any individual cell will handle that current draw unless it is totally trashed or near EOL.
So
IF you put a BMS board on each of your cells like this
eBay auction: #124396847497 gives you most flexibility to use the cells safely here or on other jobs and will look after a mismatched set of cells in the best way.
OR
Should you use a multi Cell BMS board and top and tail the wires to your holders you will likely have a spaghetti monster and a far less flexible set of batteries
NOW on BMS and do you need it/themYes and also No.
I run 30-40 packs of LiPo's (I think
) for R/C planes helis and drones none of them apart from the DJI drone packs have BMS boards or protection fitted. The Speed Controllers or Receivers in some cases monitor the overall pack voltage and shut down the motor at circa 3V/cell as we are pushing high to extreme currents the cells unloaded generally bounce straight back to 3.2-3.3V so there is simply no need for BMS and at 20-100A+ we would blow the stuffing out of the boards and we don't want additional losses.
For all my 18650 based cells and toys/projects they go in I generally have chosen to at this stage use unprotected cells but only buy this sort of solution for powering circuits as it handles the charging and protection
18650 UPS 3.3 and 5V holdersOther than that I have a couple of those single cell boards on some for set and forget use.
