This protection board can protect farad capacitors and lithium titanate batteries, and is suitable for 2.7V voltage farad capacitors and lithium titanate batteries. The protection voltage can be fine-tuned within the range of 2.5V-3V by replacing the voltage divider resistor (higher equalization voltage Need to replace the high resistance power resistor). The working principle of the circuit is that when the voltage of a single battery/capacitor is higher than the equilibrium voltage, the internal circuit discharges the battery/capacitor by turning on the transistor, and the excess power is dissipated as heat through the power resistor. The circuit equalization voltage accuracy ± 1%.

Q&A:
1. Which batteries/capacitors can be protected by this protection board, and what is the protection voltage and discharge current?

This protection board is suitable for 2.7V lithium titanate batteries and 2.7V farad capacitors, other types of batteries are not suitable. The discharge current is about 0.7A, and the default protection voltage is 2.7V. The minimum can be changed to 2.5V, and the maximum is recommended not to exceed 3V (the higher the voltage, the greater the discharge current, and the discharge resistance will be burned if the rated power exceeds the discharge resistance)

2.How many strings of batteries/capacitors is suitable for this protection board?
The single-chip protection board is suitable for any 1-6 strings of batteries/capacitors. When the number of strings is less than 6 strings, connect from the negative pole according to the wiring diagram, and leave the excess lines empty. Multiple protection boards in series can protect more strings (for example, 2 protection boards in series can protect up to 12 strings)

3. Does this protection board have over voltage protection?
The protection board has only limited over-voltage protection, not under-voltage protection

4. Does this protection board have the function of equalizing voltage?
The protection board is passively balanced, and the discharge circuit is activated only when the voltage exceeds the protection voltage. Therefore, if the voltage is to be balanced, the charging voltage needs to be set slightly higher than the protection voltage to start all balancing;
For example: 6 series of 2.7V capacitor banks, set the charging voltage to 16.5V (about 0.3V higher than the total protection voltage 16.2V), set the charging current to 0.5A (not more than 0.5A), and continue charging after full 2- 4 hours is enough.”
