MWB HC-18650 & 21700 Battery-Packs are manufactured with the highest rated Lithium-Ion cells on the market today. MWB designs and build our own BMS / PCB's that prevents the pack from over-discharging and over-charging. Each pack is welded with .375 Nickel Tabs for the best overall contact between cells, and are tested for high rated charging cycles along with high ambient temperatures. Our standard connector is the 22 gauge 2-Pin JST SM Connector that can be change depending on your needs.

Lithium battery charge indicator.
Indication levels 25% / 50% / 75% / 100%
Universal charge level indicator for Li-ion batteries (1S-8S). The module displays the battery level in real time.
If you want to periodically check the state of charge, connect a button with / without latching in the circuit.
The module allows you to set by soldering one jumper on the board (only one is allowed) the required battery configuration (number of cells under test) from 1S(3.3-4.2V) to 8S(28.6-33.6V).
Operating modes:
battery voltage exceeds N(number of battery cells) * 3.3V, one bar of the indicator will be displayed
battery voltage exceeds N*3.5V, two indicator bars will be displayed
battery voltage exceeds N * 3.7V, three bars of the indicator will be displayed
battery voltage exceeds N*3.9V, four indicator bars will be displayed
battery voltage is less than N*3.3V, 4 indicator bars will be off (battery needs to be charged).
voltage measurement range: 3 – 34 V
measurement accuracy: 2%
module dimensions : 44 x 20 x 7 mm
