Use techniques and methods

The 3S inside the title means that the three batteries are connected in series. Only three batteries can be used on the circuit board, and the rated output voltage is 11.1V. (charger 12.6V, discharger 8.7V)

The 6S in the title means that the six batteries are connected in series. Only six batteries can be used on the board, and the rated output voltage is 22.2V. (charger 25.2V, discharger 17.4V)

The superposition of the upper and lower layers is to increase the capacity without changing the voltage.

When installing the battery, the battery must face the same positive and negative poles, and the positive poles of all the batteries should face the same side.

The output power of the battery pack is determined by the performance of the battery. The better the battery performance, the greater the output current.

During the charging or discharging process of the battery, the voltage will change. The protection board of the product does not have the function of stable output voltage. The voltage filled by the battery is different from the voltage of the discharged battery, so the voltage will change.

First, determine the capacity you need.
1. If you use it as a simple battery storage device, take 3000 mA (3AH) per battery and 3.7V for ordinary lithium battery as an example, 100% ideal conversion efficiency.

(1) Each layer of 3S is voltage 3.70*3pcs=11.1v, capacity 3000mAH, energy 3.7v*3pcs*3AH=33WH
(2) Each layer of 6s is voltage 3.7v*6pcs=22.2v, capacity 3000mAH, energy 3.70*6pcs*3AH=66.6WH
(3) Buy the appropriate number of layers according to your capacity requirements.

2. If you are using the backup power supply for the appliance or the reserve power of the U AP S, you need to know the power and time of the appliance. Take 3000 mA (3AH) per battery and 3.7V for ordinary lithium battery as an example, 100% ideal conversion efficiency.
(1) Use of 100w electric appliance for 1 hour: 100WH / 11.1WH per section = 9 batteries.
100w of electrical appliances used for 2 hours need: 100ww * 2 / 11.1ww per section = 18 batteries above and so on
(2) 500w of electrical appliances used for 1 hour need: 500wH / 11.lw per section = 45 batteries or more
The use of 500w electrical appliances for 2 hours requires: 500w; *2/11.1w; each section = more than 90 batteries
And so on
(3) After selecting the number of batteries, you can select different numbers of panels.

Second, after knowing the capacity, you need to determine the voltage or power supply mode of the appliance.
(1) If you want to use it as a charging treasure for mobile phones or other U5B chargers, you need to purchase a step-down USB module and step down the 12V or 24v to 5V (this shop is available).
(2) If you want to supply power to the DC appliance or module, if the voltage required by the appliance is higher than the voltage of the battery box, you need to buy the boost module. If the voltage required by the appliance is lower than the voltage of the battery box, you need to buy the step-down module. If the appliance voltage is within the range of the battery box voltage, you need to purchase the buck-boost module.

The above is the battery box output tips

The following is the battery box charging tips
1, the battery box protection board charging limit is 8A, the charging current of each layer of battery is not recommended to exceed 2A, 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 select a charger within 4A. And so on, if the current is too high, the battery will be hot or damaged.
2. The charger must select the constant current charger, and the constant voltage power supply cannot be selected. The constant voltage power supply will cause the battery to generate more heat.
3, 3S requires a 12.6V charger to be fully charged, 6S requires a 25.2V charger to be full, if the voltage is lower than this value will be full, if the charger voltage is higher than this value 1V or more may cause damage to the protection board.
4. If there is no suitable voltage charger, or only constant voltage power supply, we can choose our constant current buck-boost module to turn ordinary constant voltage power supply into adjustable current constant current power supply.
5. If you are using a solar panel to charge the battery, you need to bring your own voltage regulator module. If the output voltage of the solar panel is too low, you need to increase the boost module. If the output voltage of the solar panel is too high, you need to increase the buck module.

Matters needing attention
★3S charging requires 12.6V charger
★6S charging requires a 25.2V charger
★ The charging current of each layer is recommended not to exceed 2A, otherwise the battery may be hot (for example, only one layer, choose 2A charger, two layers can choose 4A charger)
★ Can not be used on metal desktop, pay attention to insulation, not short circuit
★The battery looks up on the circuit board, and all the batteries are aligned and cannot be staggered.
★ Do not connect the wrong power supply, there is a logo on the circuit board, pay attention to observe
