Specially designed to handle high current demand during starting and high energy demand while parked to elimincate idling.
The battery features a built-in intelligent thermal management system, which can be automatically heated at low temperature.
Its service life is 8 to 10 years with a 5-year warranty
Connects to your phone and for real-time monitoring of battery health and SOC (state of charge) to minimize unexpected down-time.
Provide multiple protection, including overcharge protection, over-discharge protection, over-current protection and over-temperature protection. Can effectively prevent any damages to the truck, and meets the IATF 16949:2016 standard.
They are designed to be handled like a lead-acid battery, without a need for "white-glove" treatment, paving the way for drop-in replacement of lead-acid batteries and simple installation.
The Mewyeah mobile app offers functions including battery status display, forced startup, fault diagnosis, data logging, and online upgrades. On both Google Play Store or Apple App Store, search "Mewyeah Mate".
ProTips: in the setting screen, it is best to turn on "Only Show Battery" for best user experience.
ProTips: Batteries are displayed in the app as MEW-XXXM, the "XXX" matches the last 3 digits on bluetooth number on the white sticker on the top of the battery. It is recommended to install them in a numerical order based on the last 3 digits. So you can match the battery location and the bluetooth number on the app. It is also recommended to rename the battery with a unit name with a location number. As our batteries are getting popular, your app may discover the batteries from other trucks when you are at a truck stop. It is always best to have a unique name for your batteries.
Power on the battery bank:
Method 1: press the <POWER> button on the battery top, and you will see the light on the <POWER> button flash 3 times, then off and then flash 3 time, and then off, follow this pattern. This tell you the battery is in normal operation mode. Repeat this operation for all 4 batteries to power on all the batteries.
Method 2: open the Mewyeah Mate app on your phone and connect individual battery, then go to CONTROL tab, click <Force On> Button. Repeat this operation for all 4 batteries to power on all the batteries. You can use the battery flashing pattern mentioned in Method 1 to confirm the battery status.
Method 3: press the <battery communication> button to power on the whole battery bank. Make sure to check the light flashing pattern mentioned on Method 1 to confirm the battery status.
Power off the battery bank:
Method 1: press the <POWER> button on the battery top, until you see the light on the <POWER> button flash 6 times, and then off. Repeat this operation on all batteries.
Method 2: press the <battery communication> button to power off the whole battery bank. Make sure to check the light flashing pattern mentioned on Method 1 to confirm the battery status.
Note: there is no option to power off the individual battery or battery bank through the mobile app.
The battery bank is charged from the truck alternator directly.
While the vehicle is parked and engine is off, the SmartStart’s E-APU function has a built-in low-charge protection function. The SmartStart can calculate how much electricity has been charged and discharged, providing an accurate assessment of the state of charge(SOC). This allows for reserving a portion of the electricity for starting, preventing situations where excessive power usage leaves the vehicle unable to start. Additionally, the BMS in the winter can reserve electricity for heating the battery to ensure successful starts.
Equipped with a low-charge protection feature, when ambient temperatures are above 41 ° F, the reserved charge level is set at 12%, whereas when temperatures are below 41 ° F, the reserved charge level is 40%. Upon reaching the stored charge threshold, the entire vehicle will power down. In such instances, it is necessary to initiate a forced startup via the mobile application or by pressing the battery’ s forced startup button once. The vehicle’ s engine must be restarted within 2 minutes to promptly exceed the reserved charge threshold, as failure to do so will result in another stored charge-induced power down. Relying solely on monitoring battery voltage to estimate remaining power is unreliable. Battery voltage can vary depending on factors such as dynamic internal resistance at different current levels and temperature fluctuations. Therefore, estimating the remaining power based solely on battery voltage is inaccurate and frequently leads to the catastrophic situation of engine start failure.
1. Inspect the battery terminals for secure installation every three months or when high pole temperature warnings are issued from the app. Clean with a suitable solution or a lint-free cloth.
2. Before prolonged vehicle storage, fully charge the battery and disconnect the negative terminal.
3. When the SmartStart remains unused for over three months, it should be fully charged before storage, and a supplementary charge is necessary if it surpasses one month without use. Batteries that have experienced insufficient capacity due to variousreasons during usage should be recharged timely.
4. If there is any damage or corrosion on the positiveand negative terminals, they should be replaced without delay.
5. Regularly inspect the cable connections at the terminalinterface for secure fastening, and promptly replace any cables or fasteners exhibiting oxidation or corrosion.
6. In instances where vehicle maintenance needs electric or argon welding,it is important to dismantle the negative cable from the SmartStart to prevent harm to the vehicle’s low-voltage system and the lithium battery.
