We appreciate your purchase and trust in our product. Please take the time to read through the manual in detail before installing and using it. If you have any questions or need assistance regarding safety precautions, installation, or usage, please feel free to contact us using the contact details below. Product Introduction: The iTECHBM500 is a high-precision battery monitor that captures instantaneous and integrated values in real-time. The iTECHBM500 utilises 500A current shunt, the iTECHBM500 measures the discharge/ recharge currents and calculate the Ampere-hours (Ah) going in and out of the battery. The monitor provides real-time, high-precision voltage measurements through a field-installed sense wire. It is compatible with Lithium-ion, lead-acid, and nickel-metal hydride batteries. Applications: Golf Carts & Utility Vehicles Caravan & RV's Marine & Boats 4WD & Canopy Setups Battery Systems Solar Energy Storage Data Displayed: Battery Capacity Battery Voltage Battery Current Battery State of Charge (SOC) Charge-Discharge indicator Remaining Time Parameter Min Max Unit Voltage Current Capacity 10.0 80.0 V 0.0 500.0 A 0.1 9999.0 Ah Temperature -10 60 °C Backlight on Current 200 400.0 mA Voltage Accuracy ±1 % Current Accuracy ±1 % Capacity Accuracy ±1 % Included Components: iTECHBM500 (Display) 500A Current shunt Shielded wire (8M) B+ Sense wire 22AWG (1M) 4 screws Shunt holder Additional Components Needed For Installation: Additional battery cable Knock out tool 1 A fuse Battery Display: Figure 1 Charge-Discharge Indicator Low Capacity Alarm Full capacity 100.0Ah 100% 48:57 13.1V -2.04A 26W OK iTECHBM500 BATTERY MONITOR Capacity Percentage Present Present Present Remaining Voltage Current Power Time Figure 2 iTECHBM500 BATTERY MONITOR 1. Use a Jigsaw to cut a hole in the surface on which the battery monitor is to be mounted. Then put the iTECHBM500 battery monitor into the rectangular orifice, and make sure the tabs are locked. 2. If the tabs can not be locked, then use the 4 screw holes to attach the monitor from the front of the hole.

Before doing anything, disconnect all wires from the negative side of the battery 2. Cut the negative cable for the battery and crimp on new ring terminals. Alternatively, use a new wire of appropriate gauge to carry the full current demand of the system 3. Connect the shunt as show in the wiring diagram (Figure 3) Note: The negative terminal of the battery must connect directly to the B- side of the shunt and there should be no connections to the negative terminal of the battery 4. Using the sense wire, connect the ring terminal end of the wire to positive of battery. The other end connects to B+ ofshunt. Note: Do not stack smaller terminals under large ones. 5. Connect the shunt to the BM500 using the shielded wire to test. If done correctly the display will turn on. Disconnect again so remote display can be mounted.

Failure to take this step will lead to erronous SOC readings. Setting Up The Battery Monitor: 1.Ensure the battery display indicates the discharge current and the charge current correctly. Use the charge and discharge indicators to ensure it is capturing the appropriate current direction (in/out). 2. Ensure that the battery voltage is displayed correctly. 3. Fully charge the battery bank such that it reaches 100% SOC. 4. To initialize the capacity, press the button for three seconds to set the capacity to 100% 5. To enter the setting menu, press the OK button for 3s. 6. Click or button to select the setting items. CAP: 100.0 Ah HIGH V: 000.0 V LOW V: 000.0 V Alarm: 000.0 Ah iTECHBM500 BATTERY MONITOR For example, select CAP and click the OK button to enter the pre-set capacity setting. Set the value by clicking the or button to increase or decrease the capacity, clicking the OK button can select other values. After this click the button to quit the setting mode. 7. The "High V" and "Low V" parameters in the settings screen are for automatic state of charge synchronization. If the battery voltage is above "High V" the state of charge will reset to 100% and if it falls below "Low V" the state of charge will reset to 0%. Setting either of these values to zero will disable this function. Note: Generally the High/ Low V do not need to be set. The default High V is 0V, Low V is 0V, which is invalid. If you want to set, please understand the actual charge and discharge voltage of battery first. 8. Lower battery capacity limit in ampere-hours. If the battery is discharged below this limit the audible alarm will sound. Setting this value to zero will disable this function. 9. The iTECHBM500 will go into a sleep mode if the battery current drops below 300mA. To wake it from this mode, press any key. The screen will automatically wake once the battery starts charging or discharging. Turn off backlight - To turn off the backlight, long press to turn off the backlight, long press again to wake up the backlight. Click or button to increase or decrease backlight Brightness. 0~10 level.
