This Battery Holder is ideal for making your own 2S2P (7.4 Volt) Battery Pack, just insert your choice of 18650 Li-on cell and fit a connector, then you have a fully protected 2S2P Battery Pack for your project – without any soldering/welding of cells.
Please note that after installing (or re-installing) the 18650 cell(s) you will need to connect the pack to a suitable charger of correct voltage to “activate” the Protection Circuit on the PCB otherwise NO pack output will be available – this is a built-in safety feature.
18650 battery holder with PCB module designed for making 7.4V Li-Ion 18650 battery pack in 2 series 2 Parallel configuration with 5.0A rate limited by PCB installed
Battery pack watt-hour = 7.4V x cell capacity
Each holder is design to hold 4 x standard (Flat top) 18650 cell (Do NOT use button top cell)!

This battery holder is designed for standard 18650 (flat top) battery only!
Please don’t remove PCB installed on battery holder.
This battery holder is for only 2S2P battery pack.
Please don’t combine battery holder for any series / parallel connection.
After insert battery(ies), must connect to charger to enable the pcb. Otherwise, you will get “no” output from pcb!
