Hey folks!

I'm here to ask for advice on an upgrade I'm plannig = mounting and connecting additional battery to my board to increase the range. Long version follows.

A bit of background:

I'm quite new to the hobby - bought my first board (Tynee Ultra with belt drive) last year and I'm loving it. Where I'm from there are not many quality roads // cycling tracks, so I decided to upgrade the board with an off-road kit to improve my comfort on rugged surfaces. It worked like a charm and I'm really happy with it, but it took a toll on the range which I'd like to extend with a second battery.

What I'm looking for is an easy project. Both easy enough for me execute and also easy on my wallet.

My thoughts so far:

• default battery is 13S - 54,6V - 374,4WH
• it currently gives me around 25 km (not great, I know, but good enough so far)
• I would buy a slightly bigger capacity battery directly from the same manufacturer as is the board (was thinking 13S 54.6V 468Wh Samsung 50S battery)
  • key point here is that it is 100% compatible with the motors and ready to plug in
• and would mount it on top of the board between my feet
• I was thinking about doing a simple manual switch that would work like this:
  • I ride using the default battery
  • it runs out of power
  • I stop, turn off the bord, click a switch to switch to the second battery
  • (the first one gets disconnected)
  • and I continue my ride using the secondary battery

What I hope to achieve:

• approximately 2x the range, obviously
• but also no shenanigans with custom built batteries
• no shenanigans with two batteries running in parallel
• good ratio on price // effort // output
• stopping to do a manual switch is not a problem for me at all
• also when I restart the board, the controller will update the battery status on the display, which is something I'd like to have

What I need your help with // advice on:

• Have you seen // done a project like this? Do you have any tips, documentations on the wiring, pictures, links for blogs documenting such projects?
  • I have a friend who can help me with the wiring but I need to bring the solution to him. Ideally with some schema // document.
• Do you already see a problem with my approach? Something I need to look out for // be cautious about?
• Do you have a better deal on the battery off the shelf?
• The BATTERY CASE!
  • now this here is a real trouble for me
  • I would like to avoid custom 3D printed something, if possible
    • (but I have access to a 3D printer if needed and it proves to be the most reasonable option)
  • ideally I would like to buy an "off the shelf" case but all the ones that I've seen (Omni or Peli) are terribly bulky - I would love to see something compact
  • the only idea I had was to buy original Tynee battery enclosure, but it still feels a bit too big to be placed between my feet
• And basically any and every piece of advice you'd like to give me on top of that.

Thanks a lot!

Considering buying a ultra hub, but i live in norway so shipping is 99usd, which is fine, but i dont understand why there is two different eays of shipping, either i get the small battery or the big battery but late shipping..?

I just swapped wheels on my Stinger from the hydros to the boosted 105’s. Also upgraded my bushings to riptides.

My question is if I correctly installed the back wheels as I couldn’t find instructions online.

What I did was, for each of the back wheels, after removing the old hydro wheels, I first pushed the new large bearing into the new pulley, then I pushed the pulley into the new wheel as far as I could, then I just put the belt that was already on my board (same as the new one) around the new pulley, pushed in as far in as I could, and then added the final screw on the outside of the wheel to secure it in place. This seemed to be the only logical way to go about this without seeing anything online.

Did anyone do anything differently? I guess there were also 4 extra (white) bearings it comes with that you don’t use to install.

The main reason I’m asking if I installed correctly is because after riding it, I noticed the belt is coming off of the pulley, about half of the belt is not on the pulley, but I can’t push the wheel or pulley in any more than it already is. The belt hasn’t come completely off the pulley so I don’t know if it will and actually become an issue, but curious if that is normal for these types of wheels for this board?

That being said the new bushings and wheels feel great. There is also a humming sound I hear sometimes and curious if that is normal or will go away eventually?

Thanks for taking the time to read!
