1. The balance socket (the ribbon connector from the BMS) is disconnected!
2. The cables of the tape socket to the battery series are soldered in series. On the 1st cable (the black one) solder the first "-" of the battery (0V), and on Eseks next red cable in order is soldered to each next bridge (3.7V; 7.4V; 11.1V … etc.). On the last + the last red cable from the ribbon balance connector is soldered to the battery.
3. Be sure to measure the voltages between the series with a multimeter on the balance connector! There should be no sequence error! "-" of the multimeter is placed on the black wire from the connector, and the "+" of the multimeter is placed consecutively on each subsequent red. The voltages must be increased in equal steps with each measurement. If there is a wiring error, be sure to fix it, otherwise, after switching on, the board will be damaged!
4. Solder B- battery "-" cable;
5. The balance tape socket in the BMS is switched on;
6. The voltage between B is measured with a multimeter- thick cable and + of the battery. The voltage as a value must be the total voltage between "+" and "-" of the battery
7. The main one is soldered + of the battery, from + on goods and + on the charger.
8. On R.- are soldered "-" to the load and the charger.
See the connection diagram of the photos below
If they are not - load them separately and then use them in batches.
To check the condition of the battery - if the voltage of a given / certain series fall faster, it is weak in these series / damaged battery.
It is not good to mix old or weak, or different battery models together! The state of the assembled battery is relatively equal to the state of the weakest element in it!
