DATE Dx5 – connect up to five batteries and two controllers or one controller and three auxiliary outputs to this device

DATE Dx5C* – connect up to four batteries and two controllers or one controller and three auxiliary outputs to this device and the charge function. This means you can charge all your batteries at the same time, using one charger - at peace of mind!

* ensure your batteries can be charged via their discharge port (common port BMS).

Do you wish to charge your batteries at the same time, from one charger? This is a great feature if you do not wish to carry multiple chargers with you if you are out and about.

You can also use a high-powered charger since the charge load will be distributed across all of your batteries.

Your controller should indicate its maximum output. For example 22 amps or 35 amps and so on. There is normally a sticker on the controller from the manufacturer.

Now you can select a DATEx2 device with the appropriate amperage from a choice of three – 30 amp, 60 amp, or 90 amp.

The Charging port on the DATE Dx2C/Dx3C/Dx4C/Dx5C devices is always XT90S anti-spark female plug.

You can use your own charger with an appropriate cable adapter that we can also provide.

Note: The 30 amp range of devices have XT60 format connectors while the larger 60 and 90 amp devices are XT90 format connectors. Keep this in mind when considering which adapters you might need. The XT90S plugs also provide a better rain-proof protection than the XT60U plugs and are easier to replace over time if ever needed.

The performance boost is achieved by reducing something called voltage SAG.

Voltage SAG occurs when you suddenly draw a lot of power from the battery. For example, if you are at a junction and need to accelerate quickly, your voltage might go from 54V to 48V. It is a drop of 6 volts.

This phenomenon is known as voltage SAG. If we can reduce voltage SAG then we can increase speed, power, and performance.

Higher voltage = higher speed

Higher current/amps = higher torque (acceleration)

Higher power (voltage x current/amps) = higher force to ride you and all the weight you have with you, including the eBike itself.

If you are using one battery and you notice a voltage drop of say, 6 volts, then with the two batteries that will halve to 3 volts, and with three batteries that reduce further to 2V.

Let’s assume you are using fully charged 48V batteries. Fully charged these should register around 54.5V.

One battery – 6V SAG

54.5V – 5V = 48.5V

48.5V x 30 amps = 1,455 watts output power

Two batteries – 3V SAG per battery

54.5V – 3V = 51.5V

51.5V x 30 amps = 1,545 watts output power

A performance boost of 90 watts compared to one battery

Three batteries – 2V SAG per battery

54.5V – 2V = 52.5V

52.5Va x 30 amps = 1,575 watts of output power

A performance boost of 120 watts compared to one battery, and the samples can continue for 4 or 5 batteries respectively.

Since the voltage SAG drops, all that extra voltage will give you more power, torque, and speed.

Note: The voltage SAG depends on the C rate of the cells. Some are 10C, 15C, 20C, and so on. Where C = the capacity of the cell. So when they discharge instantly, they can supply xC Amps instant current.

In practice, if I get 30 miles with one battery and 30 miles with the second one, by joining them together I should get 60 miles, right? Wrong, because the load is split across the batteries then they are under less stress so you can access more of the batteries’ stored capacity, safely.

On average, our tests have shown around a 20% range boost so using the above example – 60 miles becomes 72 miles! Not bad, right!

Of course, many factors determine the range, but this is a real-world example that we have experienced, on flat terrain, on the same route with the same rider.

24V, 36V, 48V, 52V, 60V, 72V batteries along with your existing batteries, or any battery or combinations you might have, as long the voltage is 24V to 84V.

For optimum performance – use batteries with the same voltage. For example: 48V + 48V, 52V + 52V or 72V + 72V battery.

It is possible and a great benefit to use that old 48V battery together with your new 52V battery.

When you use a 52V battery and a 48V battery then the 52V battery will be used first until its voltage is the same as the 48V battery at which point the batteries will run at the same time until the 52V reaches its low voltage cut off e.g. 42V.

We recommend manually turning off the 52V battery (via the key or on/off switch) when it reaches its low voltage cut-off.

It is not practical to mix batteries with large voltage gaps, for example mixing a 72V battery with a 52V battery since their discharge cycles are completely separate.

For example, the 72V battery voltage range (full to empty) is 84V down to 60V and for the 52V battery 58.8V down to 42V, so the DATEx2 device won’t bring any extra range boost benefits in here, except the fact that you could have both batteries always connected into the system.

In this case, you need to manually turn the 72V off when it reaches 60V (when it reaches 60V while riding, not while stationary).

In this case, the voltage drop when riding (SAG) will be the same as with a single battery until the voltage is the same across both batteries, and then the voltage SAG will drop in half (with identical capacity batteries – Ah, or proportional to each battery otherwise).

With the help of the DATEx2 devices, you could safely mix different chemistry batteries – such as Lithium-Ion, LIPO, LIPOFE4, etc.

It makes no difference whatsoever. Still, the same low voltage rules apply when mixing different batteries – that is you need to manually turn off the higher voltage battery when it reaches its minimum voltage usage threshold while riding.

It doesn’t matter what voltage your batteries are when you connect them to the DATEx2 device.

It is always the higher voltage battery that will be used first and then both together when their voltages match.

When charging them through the DATE Dx2C, Dx3C, Dx4C, or Dx5, the opposite will apply, the lower voltage charged battery will be charged first until they will both reach the same voltage and then both will split their charging based on their capacity e.g. ⅓ + ⅔ for 10Ah + 20Ah batteries together or ½ + ½ when the Ah is identical.

*Beware that some BMS requires you to wait 10 seconds after turning your battery OFF and before turning them ON again.

The DATEx2 devices can be installed in just about any location on your bicycle. Often, we suggest having the DATEx2 device near your controller to reduce the amount of wiring. Less wiring makes for a neater setup.

Once installed, the DATEx2 device and adapters do not need to be unplugged again.

The heat produced by the DATEx2 device is negligible therefore no additional cooling is required. Store the DATEx2 device in a cycle pouch, within your frame, zip-tied to your seat post, it does not matter.

You can now charge all of your batteries, at the same time via a DATEx2 device that has the charging feature.

You can charge your batteries on or off your bicycle.
You can charge your batteries one at a time or all at the same time with each of the batteries’ individual chargers.
This greatly increases convenience as you only need to travel with one charger.
We recommend thinking about a higher-powered charger when charging more than one battery since most ‘stock’ chargers only provide 2 amps which means it can take a very long time to fully charge large capacity batteries.
The DATEx2 devices manage the charge to each battery so you do not have to worry, but the only requirement is that your batteries use common port BMS, which allows charge through their discharging wires.

We have a large selection of adapters available to easily and effortlessly connect your DATEx2 to your batteries and controller. You can view our adapters or contact us for any custom setup.

...and why running two, three, four, or five batteries in parallel, rather than one at a time, is the way forward for performance and range boost!

1. More Power – 1/2 or 1/3 or 1 / 4 or 1 / 5 voltage SAG decrease! For instead of a 6V drop when applying full power, the voltage drop will be 3V / 2V / 1.5V respectively 1.2V. That means 3V/5V x current assuming 30A = 90W (150W) more power! And that is across all the battery discharging curves.
2. Higher average speed – always riding 3-5V faster because of the same cut in half/fifth voltage SAG.
3. Lower temperature on your battery – Each battery will only work at 1/2, 1/3, 1/4 respectively 1/5 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 the 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. It is also, more powerful and has 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 DATE Dx2C / Dx3C / Dx4C or Dx5C. 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 cable mess and extra weight! Yes, I am personally riding with DATE Dx5C-90A and I charge all 5 batteries with a single 35A charger - the range is exceptional 297km at fast speeds!
8. Lightweight control! – Yes, you can decide how many batteries you want to ride with. 1, 2, 3, 4, 5 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 swap, 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 / Dx4 / Dx4C and four output ports with Dx5 and Dx5C

Note that the oxidation of plugs is not covered by the warranty so make sure you plug them all the way through to avoid rain oxidizing them.
Any external damage to the device voids the warranty.

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!
