Q4 Production update

The last few months have seen the team extremely busy with getting everything ready for final assembly. This update is to address where we are at and when you should expect to receive your board that you’ve been waiting so patiently for.

The team is still stationed in China overseeing part production and ensuring we can continue on our promise to deliver a high quality product that is safe to ride day in and day out.

Our journey has not been without issues. We’ve spent a great deal of time and effort ensuring all the little details are refined. Sometimes, however though we make mistakes and not everything goes exactly to plan. Along the way we’ve run into a number of bumps where parts didn’t perform as expected, suppliers let us down, the wrong material was used, among other issues. We know we’ve missed many deadlines for delivery, and for this we truly and sincerely apologise. Our intention has only ever been to build a great product for our customers. We never want our customers to be subjected to beta testing our products, so we have ensured that everything we do is right from the start before we deliver anything to customers.

We know we have some work to do in order to be better with communications, and our team is always available on live chat, and email to speak directly with customers.

Batteries

A great deal of effort has been spent on our production battery pack. We have optimised the internal structure and the BMS to be better suited to easier manufacturing and longevity. All unnecessary wires internally have been removed. The production battery backs use a potting material internally to keep the BMS and critical screws secured in place to ensure they can never come loose under extreme vibration even after years of riding. The potting also helps to protect the electronics should (in the unlikely event) water intrude into the enclosure.

Our packs have been tested to very strict standards, including UL2272. Part of our testing has included warm and cold weather testing to see the effect on battery performance. 

The final battery pack enclosures are made from glass reinforced nylon to ensure they can not only withstand shock and impact, but have a level of fire protection.

Our onboard USB-C charging is capable of outputting 11W/2.2A so you can charge your Jed Board remote, phones, tablets and even small laptops. 

Below is the raw testing data showing some of the testing we have conducted with our production battery packs. We are more than impressed with the results and the packs performed as expected, and in some cases better.

25 Degrees Celsius @ 22A Continuous Discharge

Testing 22A continuous discharge on the pack in 25 degree ambient temperature yielded a complete discharge to a capacity of 5.04Ah. The maximum temperature was 73C which is within limits of the pack design.



25 Degrees Celsius @ 25A Continuous Discharge

Testing 25A continuous discharge on the pack in 25 degree ambient temperature yielded an average continuous discharge time of 704 seconds to a capacity of 4.88Ah. Our temperature failsafes kicked in at 78C to ensure the pack remained within safe limits.



25 Degrees Celsius @ 30A Continuous Discharge

Testing 30A continuous discharge on the pack in 25 degree ambient temperature yielded an average continuous discharge time of 492 seconds to a capacity of 4.05Ah. Our temperature failsafes kicked in at 78C to ensure the pack remained within safe limits.



25 Degrees Celsius @ 40A Continuous Discharge

Testing 40A continuous discharge on the pack in 25 degree ambient temperature yielded an average continuous discharge time of 270 seconds to a capacity of 3.09Ah. Our temperature failsafes kicked in at 77C to ensure the pack remained within safe limits.


25 Degrees Celsius @ 60A Continuous Discharge

Multiple tests at 60A continuous were conducted. The first was repeated discharged 3 times with a 60 second interval between testing resulting in 1.001Ah, 1.001Ah and 0.335Ah before our temperature protection kicked in on the third test resulting in a discharge to only 0.335Ah.

The second set of testing was 60A continuous discharge, repeated 3 times with 5 minute intervals between testing resulting in 0.999Ah, 0.999Ah and 0.818Ah before our temperature protection kicked in on the third test resulting in a discharge to only 0.818Ah.



40 Degrees Celsius @ 18A Continuous Discharge

Testing 18A continuous discharge on the pack in 40 degree ambient temperature yielded a complete discharge to a capacity of 5.04Ah. The maximum temperature was 75C which is within limits of the pack design.



40 Degrees Celsius @ 20A Continuous Discharge

Testing 20A continuous discharge on the pack in 40 degree ambient temperature yielded an average continuous discharge time of 950 seconds to a capacity of 5.01Ah. Our temperature failsafes kicked in at 78C to ensure the pack remained within safe limits.



-10 Degrees Celsius @ 20A Continuous Discharge

Testing 20A continuous discharge on the pack in -10 degree ambient temperature yielded a complete discharge to a capacity of 4.96Ah. The maximum temperature was 59C which is within limits of the pack design.

Remotes

We have spent a great deal on the usability and fit and finish on the remote and we're particularly proud of the results.

The sensors have been integrated into the enclosure so when you grasp the remote, it turns on and is ready for use. After 5 minutes of not holding the remote it will automatically enter into sleep mode. The remote features an A123 LifePO4 battery with integrated protection circuit to ensure the batteries remain safe at all times.

In our testing, we have seen average battery life of continuous usage of 30 days, based on 6-8 hours/day. The ePaper display and BLE5.0 module helps to keep the usage low, giving you maximum uptime.

The enclosure features a rubberised coating that makes it comfortable to hold for extended periods of time and our lanyard is made from a soft neopreen material.

Delivery

Where are at with delivery and when will you get your board? Based on our current timeline we expect to have all components ready to have the first batch of boards complete by the start of December, at which point we can begin air freighting the first of the boards to customers.

Production planning has begun for our second batch and we have started ordering parts for the second batch of 1000 units with a plan for delivery in Q1 2019.

Pre-orders on the website will finish at the end of November and our retail pricing will have a slight increase from December (this doesn't affect existing pre-order customers).

Keep an eye on our social media for more content coming of the finished boards.

Our next blog will cover more on electronics, as well as our iOS/Android apps.
