Balance and protection electronics
An important part of any battery module is the balance and protection electronics. The most common solution is the BMS123 Smart BMS123. This advanced LiFePO4 battery monitoring and management solution supports Bluetooth connectivity to your phone, iPad, tablet, or other device. A free app for Android and iOS is included.

Common Connection Diagrams for BMS & SBM
Demonstration of BMS123 connection including charger, appliance and increasingly important fuses and switches.

SBM is a simple solution offering basic protection, the diagram shows a version with 16 cells connected to the charger and fuses.

Winston cell wiring produces cells with an easily assembled square shape, the terminals are made on screws allowing simple installation with a wrench.

An important part of any battery module is the connection between the cells. Original copper connectors are made of several thin layers, which ensures ideal flexibility and conductivity.
Before assembly, do not forget to clean the terminals and connectors from oxidation (with sandpaper or similar paper). Oxidized contacts can have very high resistance and cause the battery to become unbalanced.
A cheap solution is plastic caps, which prevent unwanted short-circuiting and make it easier to mark plus and minus (red and black colors are available).
