Instructions for use

In the title, 3S means that three batteries are connected in series. Only three batteries can be mounted on the circuit board, and the rated output voltage is 11.1V. (Full 12.6V, after putting 8.7V)
In the title, 6S means that six batteries are connected in series. Only six batteries can be used on the circuit board, and the rated output voltage is 22.2V. (Full 25.2V, after discharging 17.4V)
The superposition of the upper and lower layers is to increase the capacity without changing the voltage.
When installing the batteries, the positive and negative directions of the batteries must be the same.
The positive poles all face the same side.
The output power of the battery box is determined by the performance of the battery. The better the battery performance, the better the output power.
The greater the current
During the battery charging or discharging process, the voltage will change, and the protection board of the product will not
It has the function of stabilizing the output voltage, the voltage of the battery is fully charged and the voltage of the discharged battery is ot the same, so the voltage will change.
The first is to determine the capacity you need:
1. If you use it as a pure battery for energy storage, use 3000 per battery
Milliampere (3AH), ordinary lithium battery rated voltage 3.7v as an example, 100% ideal conversion efficiency
As follows:
(1) 3s each layer is voltage 3.7v*3 knots = 11.1v capacity 3000mAH, energy
3.7 U *3 knots*3AH=33wH
(2) 6s each layer is voltage 3.7*6 knots = 22.2v capacity 3000mAH, energy
3.7 v* 6 sections*3AH=66.6wH
(3) Purchase the appropriate number of layers according to your capacity requirements.

2. If you are used as a backup power supply for electrical appliances or reserve power for uAPs
For the pool, you need to know the power of the electrical appliances and the time of use. Per battery
3000 mA (3AH), ordinary lithium battery rated voltage 3.7v as an example, 100% ideal conversion
Under efficiency:
(1) 100w electrical appliances need to be used for 1 hour: 100wH/ 11.1WH=9 electricity saving per section Pool
100w electrical appliances need to be used for 2 hours: 100wH *2/ 11.1WH per cell = more than 18 batteries,And so on
(2) 500w electrical appliances need to be used for 1 hour: 500wH/11.WH each = 45 batteries or more
500w electrical appliances need to be used for 2 hours: 500wH*2/11. 1WH each section=90 sections
Above battery,
And so on (3) After knowing the number of batteries, select a different number of battery boards.
2. After knowing the capacity, you need to determine the voltage or power supply mode of the electrical appliance:
(1) If you want to use it as a power bank for mobile phones or other USB chargers,
Need to buy a USB step-down module to step down 12 or 24v to 5v
(2) If you want to supply power to DC appliances or modules, if the voltage required by the electrical appliance is higher than the voltage of the battery box, you need to buy a booster module, and if the voltage required by the electrical appliance is lower than the voltage of the battery box, you need to buy a step-down module. If the voltage of the electrical appliance is within the voltage range of the battery box, you need to purchase a buck-boost module
The above are the tips for using battery box output
The following are the battery box charging tips
1. The charging limit of the battery box protection board is 8A. The charging current of each layer of battery is not recommended to exceed two amps. If there is only one layer of battery box, it is recommended to choose a charger with current less than 2A. If it is a two-layer battery and it is recommended to choose a charger within 4A. By analogy, if the current is too large, the battery will heat up or be damaged.
2. The charger must choose a constant current charger, not a constant voltage power supply, which will cause the battery to generate more heat.
3. 3s needs a 12. 6V charger to fully charge, 6s needs a 25.2V charger to fully charge, if the voltage is lower than this value, it will be dissatisfied, if the charger voltage is higher than this value and more than 1V, it may cause the protection board damage.
4. If there is no charger with suitable voltage, or only constant voltage power supply, you can choose a constant current buck-boost module to change the ordinary constant voltage power supply into a constant current power supply with adjustable current.
5. If you are using solar panels to charge the battery, you need to prepare your own voltage regulator module, if the output voltage of the solar panel is too low, you need to add a boost module, if the output voltage of the solar panel is too high, you need to add a step-down module.
