Meet the DATEx2 eBike parallel battery safety device.
The DATEx2 device allows you to safely connect more than one eBike battery to your bike at the same time! Safely use up to three batteries in parallel with the DateX to boost your range, power, and lifecycles. Better range. Prolong and protect your eBike battery.
BOOST your BIKE | BOOST your RIDE | BOOST your EXPERIENCE
With the DATEx2 device, you can combine any battery, for example, 52V with 48V or even 36V, regardless of their chemistry, voltage, state of charge, or capacity as long as the controller supports the voltage and the hard-limits are not exceeded.
Although it may seem simple, adding additional batteries to your ebike is a major challenge. Connecting eBike batteries in parallel, without the DATEx2 device, can be is EXTREMELY dangerous. For example, if the batteries have different voltages, chemistry, and or state of charge you risk permanent damage or in extreme circumstances explosion or fire!.
The DATEx2 solves this: You can now combine batteries that have different chemistries, voltages, outputs and or state of charge. The device will manage everything and protect your ride.
When using two different voltages, the DATEx2 will use the battery with the higher voltage first, then engage the 2nd/3rd battery when within the lower voltage battery’s charge.
For example: If you combine a 52V and 48V Battery, the DATEx2 will take current from the 52V only, until 54V is reached. From there, both batteries will output until 43V together. After 43V, only the 48V will be able to put out charge until 40V is reached. As a result, we recommend manually turning off your 52V if it does not have an intelligent BMS.
