Tips and methods:
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, 8.7v after release)
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, 17.4v after release)
The superposition of upper and lower layers is to increase the capacity without changing the voltage,
When installing the batteries, the orientation of the batteries must be the same, and the anodes of all batteries should 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 greater the output current.
The voltage will change during the battery charging or discharging process, the product's protection board does not have the function of output voltage stabilization, the battery full voltage and the discharged voltage are
Not the same, so the voltage will change.
1. The first is to determine the capacity you need
1.If you are using it as a pure battery energy storage, take 3000 mAh (3AH) per battery and 3.7v rated for an ordinary lithium battery as an example, 100% ideal conversion efficiency
(1) Each layer in 3s is voltage 3.7v*3 knots=11.1v capacity 3000AH energy 3.7v*3 knots*3AH=33wH
(2) Each layer in 6s is voltage 3.7v*6 knots = 22.2v capacity 3000MA energy 3.76 knots 3ah66.6w
(3) Buy the corresponding number of layers according to your capacity requirements
2. If you are using it as a backup power source for an electrical appliance or a reserve battery for uAPs, you need to know the electrical appliance power and usage time. Per battery
3000mA (3AH), ordinary lithium battery rated 3.7v as an example, under 100% ideal conversion efficiency.
(1) 100w electrical appliances need to use for 1 hour: 100wH/ 11.1w per battery = 9 batteries
100w electrical appliances require 2 hours of use: 100w*2/ 11.1wH per battery = 18 or more batteries
And so on
(2) 500w electrical appliances need to be used for 1 hour: 500w/11.1wH each = 45 batteries or more
500w electrical appliances require 2 hours of use: 500wH*2/11.1wH each = 90 or more batteries
And so on
(3) After you know the number of batteries, you can choose a different number of battery boards.
Second, after knowing the capacity, you need to determine the voltage or power supply method of the electrical appliance
(1) If you want to use it as a charging treasure for mobile phones or other USB chargers, you need to buy a step-down usB 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 appliance is higher than the voltage of the dry battery box, you need to buy a booster module.
To lower the voltage of the dry battery box, you need to buy a buck module. If the electrical appliance is pressed within the voltage range of the battery box, you need to buy a buck-boost module.
The above are tips for using the 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 amperes. If there is only one layer of battery box, it is recommended to choose the current lower and two.
Ann's charger. 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 become hot or damaged
2. The charger must choose a constant current charger, and a constant voltage power supply cannot be selected. The constant voltage power supply will cause the battery to heat more
3. 3s requires a charger of 12.6 volts to be fully charged, and 6s requires a charger of 25.2 volts to be fully charged. If the voltage is low, this value will not be fully charged.
If the voltage of the device is higher than 1 volt, the protection board may be damaged.
4.If there is no charger with a suitable voltage, or only a constant voltage power supply, you can choose our constant current buck-boost module to change the ordinary constant voltage power supply to an adjustable current
Constant current power supply.
5.If you use 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 add a boost module.If the solar panel
If the output voltage is too high, you need to add a buck module.For specific wiring, please contact us.
Precautions:
Please read the following carefully before buying
3S charging requires 12.6V charger
6S charging requires 25.2V charger
It is recommended that the charging current of each layer does not exceed 2A, otherwise the battery may heat up (for example, only one layer, choose 2A charger, two layers can choose 4A charger)
Can not be used on a metal desktop, pay attention to insulation and do not short circuit
Looking at the circuit board with the battery facing upward, all batteries should be in the same direction and cannot be staggered
Don't connect the wrong power supply positive and negative, there are signs on the circuit board, pay attention to observe
