供应电量检测显示器 可调，蜂鸣校准电压12～260v

1.产品概述：

现阶段大部分电动车电量表都是 电压表， 只要一加速 或启动 电流较大 电压下降较快，当然 ”电量“ 也下降的较快！该电量表用于监测12-24V铅酸蓄电池的剩余容量（订货是注明电池电压），该电量表采用*特算法，依据蓄电池放电曲线来计算剩余电量，是一种真正的**的数字式电量表，对电池电量检测的准确度可达±10％。可以用于电动汽车 电动游览车 电动叉车 电动三轮车 电动自行车等。

2.产品特性：

●.采用10个红色发光二级管排灯直观显示蓄电池电量，每个灯的亮灭代表电池电量10%的增减。

●.电池放电达80%，双闪灯闪烁发出“电量耗尽”报警。

●.充电自动识别，只有真正的充电才会指示电量增加，“假”充满电池识别功能。
●.结构紧凑，易于安装。电路板尺寸为68mm*37mm。

●.工作电压为电池电压的+25%到-25% 。直接电池供电，*外接独立电源。定货时请说明电池电压，12V,24V，36V。。。。。。，一直可以到260V，24V以下的价格为30元，**24V为70元，请拍前联系店家，以免耽误发货时间。

● 接线简单只需直接连接电池两端就好了（分清正负） 

 At this stage the majority of electric vehicle fuel gauges are the voltage meter, as long as an acceleration or a larger voltage drop faster start-up current, of course, "power" also fall faster! The fuel gauges used to monitor the 12-24V lead-acid battery residual capacity (order is specified battery voltage), the electricity used in the table a unique algorithm, based on battery discharge curve to calculate the remaining capacity, is a truly accurate digital power table, right battery detection accuracy up to ± 10%. Can be used in electric vehicles Electric motor tricycle tour electric forklift electric bicycles. 

2. Product Features: 

●. With 10 red light-emitting diode row of lights visual display and battery power, on behalf of each lamp light battery eliminate 10% of the change. 

●. Battery discharge up to 80%, two flashing lights flashing issued a "charge depletion" Alarm. 

●. Charging auto-identification, only a real charge will direct more power consumption, "false" full cell recognition. 
●. Compact, easy to install. Circuit board size is 68mm * 37mm. 

●. Working voltage for the battery voltage of +25% to -25%. Directly to the battery-powered, no external independent power supply. When ordering please indicate the battery voltage, 12V, 24V, 36V. . . . . . , Has been able to 260V, 24V below the price of 30 yuan to 70 yuan higher than 24V, please contact before making shops, so as not to delay the time of delivery. 

● wiring simple and direct connection to the battery ends just like the (to distinguish between positive and negative)
