12 Reasons to get the DATEx2 parallel battery adapter and why running two or three batteries in parallel, rather than one at the time, is the way forward for performance and range boost!
  1. More Power – 1/2 or 1/3 voltage SAG decrease! E.g. instead of a 6V drop when applying full power, the voltage drop will be 3V respectively 2V. That means 3V/4V x current assuming 30A = 90W (120W) more power! And that is across all the battery discharging curves.
  2. Higher average speed – Literally always riding 3-4V faster because of the same cut in half/third voltage SAG.
  3. Lower temperature on your battery – Each battery will only work at 1/2 respectively 1/3 of the load. All that heat with a single battery means wasted energy as heat. In our tests, the battery temp dropped from 70°C to 52°C.
  4. Longer battery ride – Since you will now boost your range, you will charge more often to just 90% or 80% of both batteries, and they will always work at half the load, so their life span can be considerably improved. Still at least once per week charge you 100% so that the BMS will get a chance to do the load balancing, properly at low current E.g., 2amp overnight.
  5. RANGE! – All the wasted heat and SAG will now become extra RANGE! In real world we did 30 miles per battery and 70 miles with the Dx2. So 10 extra miles by just riding with both batteries together via Dx2. And also, more powerful and a bit higher average speed.
  6. Peace of mind – You just plug it once and forget.
  7. Charge with a single more powerful charger at once – charging multiple batteries with one charger, at the same time, with the DATEx2 DX2C or DX3C. Take a single charger with you on your long trip hauls. And don’t mess with 220V/110V splitters, two/three chargers, and all that cables mess and extra weight!
  8. Lightweight control! – Yes, you can decide how many batteries you want to ride with. 1, 2 or 3 is that easy, depending on the needed range/power/route. Maybe you are going on a short ride, so leave two batteries at home and ride with just one. Not a problem.
  9. Make most of your batteries – by mixing your old 48V battery with your newer 52V ones without worrying.
  10. Plug and forget. Always ride at peace of mind!
  11. Stop swapping batteries – especially batteries in the frame or cradle which are hard to be swapped, especially in rain or nasty weather conditions.
  12. Get more output ports! – 
Need to plug your fancy powerful light?
Need to plug your 2WD second controller?
Or maybe your controller temp measuring device?
Or perhaps your 12V DC to DC step-down converter?
Absolutely no problem.
You get two output ports with Dx2/Dx2C and three ports with Dx3/Dx3C♥️
Bottom line?

Forget about any range anxiety. Increase your power output. Protect your batteries! Just plug in, tidy up the wiring and forget. Focus on your improved riding experience!

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.

Specification:

Regen Braking: NOT COMPATIBLE, DO NOT USE
Connection Type: XT60 Connectors
Amperage Rating: 30 amp

DATEx2-Dx2-Use-Example

The DATEx2 Dx2 suitable for use with up to 2 eBike batteries but does not have the charge function so the batteries must be charged individually on or off the bicycle.

In this example:

  1. RAD Male to XT60 female – 50cm length. This connects your 2nd battery, perhaps mounted on your rear rack to the DATEx2 device.
  2. RAD Female to XT60 male. This connects the DATEx2 device to your controller.
  3. RAD Male to XT60 female. This connects your primary/frame battery to the DATEx2 device

The DATEx2 Dx2C suitable for use with up to 2 eBike batteries includes the charge function so the batteries can be charged at the same time in-situ or individually on or off the bicycle.

In this example:

  1. RAD Male to XT60 female – 200cm length. This connects your 2nd battery, perhaps mounted on your rear rack to the DATEx2 device.
  2. RAD Female to XT60 male. This connects the DATEx2 device to your controller.
  3. RAD Male to XT60 female. This connects your primary/frame battery to the DATEx2 device

    This is an extraordinary device, worth every penny if you're running two or more batteries. If nothing else, it removes the fear of voltage sag, leaving only range anxiety to contend with :-) let's hope some giant doesn't come in, buy the developer up and put the price up as a consequence.

    I live in a very hilly area and this little magic black box also gives extra juice to the motor which helps too.

    And if only there were more people like Gareth running businesses. Friendly, helpful, knowledgeable and funny - I have benefitted hugely from his generosity of time and advice on many occasions. Top bloke, top company.

    This Datex2 is amazing, after I upgraded my motor and controller on my RadRover my pedal assist didn’t work very good at all for some reason, I’ve heard others say the same thing, now that I have the Datex2 installed pedal assist works again (crazy) only better then it ever did, and the distance I get from two 52v battery’s hooked to this device has totally removed my range anxiety, I take long rides out in the country and still have power to spare by the time I get back home, people that don’t have the DateX2 installed are really missing out, it’s like giving your bikes electrical system a professional tuneup.

    I have 2 different batteries on my 2020 Radrover 5 ebike. The first one is the original 48v battery and the other is a 52v rear rack battery.



     It was super easy to hook with Gareth's easy instructions. The 2 inputs are for the batteries to plug in. The 2 outputs are for 2 separate controllers. If you only need one controller, the other is not used.




    I turn the rear rack battery on first and then the front battery before powering up my 35 amp Bolton controller. The bike seems to go forever with the 2 batteries.




    There is nothing on the market that can do what the DATEx2 does. I don't worry about my batteries knowing how reliable the device is. It is well worth the money considering the peace of mind you get.

    I have a Radrover 5 ebike and so does my wife. I recently bought 2 rear rack batteries to extend our range. Mine is a 52v battery to go with my 48v Rad battery.



    I heard about the DATEx2 and that it allows you to hook up 2 batteries no matter what the voltage is, the range, or charge level.



    Gareth from biggamebikes explained how to hook it up and it was easy to install. It is amazing and the only device on the market that does what it does.



    The DATEx2 gives me peace of mind and we'll worth the money.

    I’ve just fitted a second battery to my Rhino along with a DateX2 my egg rider is showing over 80 miles range on pedal-assist 3 which is very impressive. I’m now looking for advice to fit the battery carrier in a good and secure way. It’s currently bolted down and then with a cable tie at the other end but I’m after something that’s more secure and better looking. The DateX is fairly secure and is cable tied in....... Any experience or thoughts on this 😊👍

    Absolutely brilliant. Running two 48v batteries - 14ah and 13ah. I can charge both batteries, at the same time from one charger. Charge time is about 14 hours but Gareth said he can source 5 or 10 amp fast chargers which will reduce charge time. Such a great investment!
