ماژول نمایشگر سطح شارژ باترى لیتیومی تک سل 4.2V

معرفی

این ماژول بر اساس سطح ولتاژ و میزان شارژ باتری (1 سل) سطح شارژ باتری ها را نمایش می‌دهد. جهت سنجش میزان شارژ باتری لیتیوم تک سل 3.3 تا 4.2 ولت کاربرد دارد. این ماژول با سگمنت طرح باتری است و از این رو نمایش سطح شارژ را به صورت گرافیکی می‌توان دید. ابعاد کالا 43X20 میلی متر و ابعاد بارگراف 31X20 میلی متر است.

Introduction

Strictly according to the diagram wiring: 0V(B-)3.7V(B+), Do not deliberately short circuit.
After the line is connected, Need to charge first, then have output.
When the battery is connected in series with 3 groups, Please ensure that the voltage of each battery is the same. If not same, please fill in each set of batteriesand then use.
Do not mix the good battery and the battery.
The capacity of the battery internal resistance is closer will be better.
Attention: Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better. Please buyers know the professional knowledge of this module before buyingDue to different producing batches, product details might be a little different. If you minding the difference, please buy it carefully.Please allow 1-5mm differs due to manual measurement.Item color displayed in photos may be showing slightly different on your computer monitor since monitors are not calibrated same.

1.Battery type electricity quantity display
2.Wide application fields:lithium battery
3.Using Method:connect display board positive and negative port with tested battery positive and negative port,digital tube will display real-time battery electricity quantity
4.Digital Color:outline red,display block blue (when battery electricity quantity is full,it will be all on)

Display Electricity Quantity Parameter:
1.When battery voltage is over 3.3V,it will illuminate 1 block electricity quantity (note:N represents battery quantity)
2.When battery voltage is over 3.5V,it will illuminate 2 blocks electricity quantity
3.When battery voltage is over 3.7V,it will illuminate 3 blocks electricity quantity
4.When battery voltage is over 3.9V,it will illuminate 4 blocks electricity quantity
5.When battery voltage is less than 3.3V,4 blocks display will be off;it represents battery is less than 3.3V,and you can charge the battery.
