those rumble strips were a huge contributor to the problem. ruxx could have probably kept the crash to himself it was just the beveled concrete or dirt.
it looks so gnar when he hits them. they are big.

This was so crazy to see happen in person. Glad you both got out okay!

So envious of Adamās lens. To bad it costs so much $$ haha

Actually, the side of the track that Ruxx hit is not rumble strip at all, its just normal curb. He would have crashed worse if he didnāt have the big tires though due to the slope of those curbs

oh i thought all the turns had those rumble stripsā¦ they were crazy to an esk8.

No, generally, most inside corners were curbs

Thatās some good racing, up until you got hit.

Put together the rest of my footage into a āraceday cutā to document the weekend. Lots of great race footage.
If anyoneās feeling 23 minutes of lightly edited video, timestamps are in the description.

How does your charging setup go on race day? Ever have any issues getting back to full between heats?
Huh, I somehow never mentioned this! Great question. Hereās a winding, wordy answer.
Around the same time I switched this board to 15s, I bought a master v4(EUC). I bought a Roger Charger RC/CC to be able to do multi-leg long distance rides with the wheel (a roger charger is just a compact, high power CV/CC power supply).
Of all of Rogerās models, I got the RC/CC primarily because it can output lower voltages, so it could do double duty as a esk8 charger.
Having the roger charger is partially why I upgraded to 15s (I didnāt need to buy another charger)
The Roger Charger RC/CC is now the primary/only way that I charge this board. Being able to adjust the current to match the amount of time I have to charge is very nice (limit battery stress).
I was wrong
I think itās notable that I didnāt always feel this way, and I now believe my opinion from earlier this year was/is wrong .
Iāve done a complete 180 since then. Iāve seen the light.
I wish I did this so much sooner;
- Cost - I have a huge pile of brick chargers that are now collecting dust on a shelf. The RC/CC is less then the cost of that pile, If I āinvestedā in the roger charger sooner, I wouldāve saved a bunch of money on those chargers that Iāve bought for different currents and voltages over the years. If youāre like me and have a fleet of boards and your raceboard seems to constantly be changing voltage of your raceboard, it definitely makes sense.
if you want some cheap chargers keep an eye out for a sale thread at some point - Speed - Being able to pump as much current as I want into my board on raceday is an obvious bonus. The limiting factor is my ZBMS, but also not really. Charging at 12A, my legs take longer to recharge then the board does.
- Speed (again) - (assuming Iām not spending $100+ on fast chargers for each of my boards, because I donāt) When charging multiple boards, using the Roger Charger is so fast that it often takes as long (or less) as charging them in parallel with their dedicated charger would take.
- Logistics - Having one, compact charger is significantly easier then a bunch of discrete chargers. Really helps for eks8 events, where Iām often bringing 3-4 boards. Less bulk in the toolbox.
Now to actually answer to your question lol;
Absolutely FANTASTIC. Highly recommend a similar route if youāre looking for a solution.
TEF1
TEF1 was about 3~4 miles of high speed racing at a time, so my board was definitely close voltage sag after every race(~40%) and needed to be topped up.
Moe graciously let us use his generator at the race. I left my RC/CC plugged in all day, set to 15s and 12A (~700W). I would come off the track, park my board, and plug in the XT60 like it was a ground tether. I also had a USB C that I would simultaneously plug in my Insta360. Took 10 seconds.
Every time I went to use the board, I had a full charge. It just worked ^TM
iCharger x12
My old icharger x12 setup, took several minutes of setup to start charging. Better then opening the bellypan every time, but still an unwelcome interruption to raceday, frequently pulling me away from conversations with fellow racers. Not to mention an annoying hassle to deal with.
It did cause me a bit of a panic when it suddenly stopped charging in the middle of the day. Thinking the worse, I disassembled the whole boardās charging setup and checked my cell voltages(Thanks @HAIRYMANJACK and @derekstavis for the multimeters). Shockingly, charging in direct sun 20% faster then zbms spec will overheat it. Lesson learned.
TLDR; the problem existed between the helmet and board.
i2s Track nights
I can do about 8~9 miles (3~4 stints) on a charge.
Tuesdays at SD i2s Nights, we set up track next to EV chargers. With an J1772 to Nema 5-15 adaptor, the boardās parking space becomes at the charger like at TEF1.
With this setup, Iāve been able to do 7~8 stints per night. More practice, yay!
Iāve found that charging at 400~600W about matches the rate that my legs recover. Any faster is unnecessary because itāll be done before Iām able to keep going.
I think I couldāve charged at a similar (slower) rate at TEF1 and been fine.
Wow, what a load of word vomit.
Hereās a sick photo @Lyfe_Of_Jimmy got of me at i2s SD this Saturday.

Iām currently using 2 sets of 6 of the hrb 9.5ās which seems to do the job for i2s meets. Iāve usually had enough by the time Iāve used those. Reason I asked though, Iāve signed up for xerace in Prague too so was thinking your setup may be the ideal option.
Iāll be able to pack 2 of the 9.5ah packs in my hand carry and only need to purchase and send another 4 new ones over there. Recharging the 1 set would be a lot more convenient and cheaper than hot swapping the 2 and then trying to get rid of all those packs on the used market.
What was your plan? Thatās the best Iāve come up with so far.
Good question. Iāll lyk when I figure it out 
Probably same as what Iāve got set up now. Ship my batteries, Ship or check my board, gear, and roger charger in the pelican case. Remate the batteries with my board when I get to Europe.

That pelicase is a score. Thatās another thing for the shopping list.
Itād be great to be able to ship packs but from memory was a major issue looking into esk8con last year. I thought about hand carrying 99wh/hr packs but even then it seems youāre only allowed 2 of those now.
I think the 2-pack limit is for batteries 101Wh-160Wh
Depends on the airline

Really?! Considering pretty much everything we use nowadays has a battery in it it seems implausible. eg. I tend to travel with multiple insta360 and GoPro batteries, are they really gnna stop me for that?
Either way, incredibly excited for yall to come to race in Prague, if you need anything or have any question feel free to ask! Iām more than happy to help : )
