Thanks a bunch for the info. The guy messaged me 2 months ago and had them at that time but since then I locally tested and blew my cash on a new Pint. No regrets! It's my favorite version so far.
This battery looks like a super simple plug and play mod and the instructions are good. I've been an electronics guy for 40 years so there's nothing here that looks weird to me.
I'm sure the guy is an awesome dude but I'm just a customer and I'm not asking for a favor. I would just like conformation of stock before I buy anything anywhere...Nothing personal. Communication problems when business is concerned seems strange to me.
Btw , The Fang guy behaved the same way and so I made 3 different custom sets for the heck of it to test the concept. It was a waste of time for me. I tried some real ones later and I think mine were better but neither made any difference to me. I can and will make my own battery mod if I have to. I have already found and priced the cells. I have all the other hardware on my shelf. I was also thinking of adding a small illuminated battery voltage monitor (DVM) that could be mounted in or on the fender. Unfortunately I don't know how I would make the two little plastic satellite battery enclosures yet . Thanks again!
It's not a big deal either way. I'm ready to pull the trigger now and maybe for a few more days but I may get distracted. I've got several other projects and then there is the Christmas thing around the corner.

Anyone know if Two-X batteries are available? The site has no phone and no one is answering any questions or Facebook messages? Maybe Tweet? I know I'm way behind in this social media crap but I don't get it. I would really like to buy one if they are available or if the company is still in business. I've been trying for 2 weeks. I even made a stupid Facebook acct just to try and make contact. I'm not interested in back ordering anything anymore.... but that's my problem I guess. So do I need a twitter account know? I know it probably makes no difference, but I guarantee I can find something else to spend $500 on fast. I'm not mad, I'm just baffled. The mod looks like a great project for an old V1. I guess next option will just be to build my own but this kit looks very well though out to me. Please help.

My opinion is the Pint kills all the others for me. I ride 95% pavement and cross a few grass patches a little and I love how fast this thing turns. Feels like riding the trees on a snowboard. Off-road is not my thing on a self balancing skateboard. I really prefer my 2000w 29er fat tire e-mountain bike BY FAR for off road.
Lately I was in great need of a new toy and was trying to decide between an XR and a Pint. They are crazy different. I am so grateful I got to test the crap out all of the boards side by side. I'm planning on putting the Two-x battery upgrade on my V1 soon and then I'll have a long range cruiser in my quiver. I realize the XR has the bigger 750 motor and my V1 has a 500w but honestly they feel the same to me.
I still love both machines for what they are and don't want to give one up. I ride the Pint more for sure. Nimble is the word for sure!

I'm really sorry for all of you guys with your BT issues. I can see how it would be a disappointment with the signal drops. I've been in electronics since tubes and relay logic. I've been RC 'ing for about 40 yrs and I still work with high energy RF semiconductor etchers every week. RF can be a real bugger to work with. With all that said, BT and all the new fancy high tech Arduino stuff humbles almost everyone these days. It's all new too me as well. I see noise all the time in my Quadcopter projects which can easily ruin your day with a crash. The high energy stuff will kill you forever and I've seen a man get cooked. I just bought a new Pint and I kinda knew what I was getting into. I have been able to duplicate the close range dropouts also several ways and I'm pretty sure y'all don't want to hear this. One is the inherent designs with the 750w motors. My V1 with it's 500w motor gets 3x range than all the other boards. If you add more power electronics generally get noisier. If you also start adding up all the other possible RF signal transmission problems with 2.4 Ghz , like slow speed , low power, susceptible to passing through water/organics/your body , different physical positions , I know y'all are really going to hate is it's very susceptible to other BT tx/rx devices like earbuds and speakers even coming from different devices. For instance if I use any BT earbuds on my new Iphone 6s along with the BT of the board I get basically NO range. If I run the OW BT app on my cheap little Android device (no sim card) and my any BT buds on my Iphone I'm getting 10-20ft of range with no drop outs. I get about 30+ feet with my V1 but it gets a lot worst if use it with the Iphone as mentioned above.
It may be possible that the PID's could be tweaked a someday or it could just need a ferrite bead or a little RF filter, but I got a feeling that there are a bunch of variables FM was dealing with in this machine.
Good for me that I don't care. I love the light bar and that's mostly what I use for monitoring my power.I'm really stoked how fast and smooth this thing turns, and I even like the Sure stop idea when I'm just riding and not trying my stupid Darwin award tricks. My dang feet are so big , I'm hang'n about 3" front and back in the rear. I've always been challenged getting enough foot off the front pad to stop. I have definitely gotten better at stopping my V1.
I still love em both and I am SO glad I got the Pint. I feel like they make a great quiver and I even got my son to ride with me 1 out of 12 times in the last 3 days. He's REALLY sore ...LOL but he did great and it's a real change riding with someone for me. I love 2 to 4am in morning in the dark and quite and no one see me doing dumb stuff.

I bet FM will hook you guys up with a good solution soon. I think they care and really want everyone happy. Y'all hang in there...
Good luck and good riding!

I waited for a local business here in town to get the Pints before considering to buy another board. I took my fully upgraded V1 which has a new battery and tire and spent 2 hours riding everything even including a new Boosted board.
Everything I rode was awesome! I am absolutely satisfied with my V1 and maybe someday I will add a Two-X get the extra range . Eyes closed I could barely tell the difference between my V1 and an XR in a smooth parking lot. I actually like my V1 foot pads better than the stock XR's . The V1 and +'s are lighter so "in my opinion" a little easier to throw around but there's no need for that anymore with a Pint. The Pint is a different animal PERIOD...for me. I listened to all the negative BS , whining, and disappointing predictions over the last year and got really bummed. I'm so glad I waited to try for myself.
Do yourselves a favor and wait for products to hit the ground, try them side by side and make your own minds up.
I bought the Pint as a compliment to my V1 not a replacement.
Pint - Lil Pepe turning /freestyle tear up the pavement machine
V1 - Giant slalom big arc carving machine.
I'm a 6' 250 lb avid snowboarder /surfer /kiteboarder and this Pint will be what you make it. It is definitely not a toy. I think all the boards could be considered beginner boards if you are a beginner and dangerous if you are reckless and don't learn to respect their limits. Oh yea, my little Jelly phone (no sim card) still has about 30ft of range with this new board so no extension cords or special antennas necessary if decide to use it LOL. I got my much wanted power level monitor so it's perfect now. The Pint ROCKS!!!!
and I don't plan on bothering with a phone while using it...That's just me....
Way to go again Future Motion! Thank you F1 Racing Austin Tx !!! They have a whole stack of em yall...go get you one .
BEST DAY EVER!!!!
Ride for the love of it

@Senior-Coffee I also love the light bar power monitors on the Pint. They should have had those from the get go on all the boards.
Seams like there was already a big discussion about Bluetooth problems a long time ago? I'm still getting about 20-25ft of range to the Pint and have zero problems with any FM boards since I changed my monitor device.(Jelly with no Sim card ). Works GREAT! It also has MP3 on it which I really like. Battery lasts for 4-5 rides or more, has a nice velcro strap that works on my wrist guard, and the display is better than all the watches I tried.

@b0ardski Oh hell yea, Max Smart shoe phones!!! I love the little rotatory dial and chin protector/mic and just think if they added Siri ?... Just think we could have voice controlled cell and BT shoes. Of coarse they would have to make them Regular and Fakey so everyone could be happy. But for sure, nobody would ever ask to use your phone . he he
Actually , maybe a voice controlled OW app via your ear buds /Siri or whatever might be pretty cool. Siri ? .....Speed? ,Distance?, Battery? Lights on/off
and we could always have eyes on the road.

@a_onekatie It's all good. I promise I am not trying to insult or question anyone's personal needs. All I meant to say is after over 1000mi on my V1 and few rides on various other models, I found none of the problems you guys are having. I did have a BT issue with my original Iphone 6s 2yrs ago, I accidentally drowned that piece of crap and got a new Iphone 6s insurance replacement. It gives me about 3 feet more range but my little Jelly phone kills it...like across the house in a different room reception. Happy trails....

Is it not possible this is not just another user problem or your connection devices? I've connected with six different boards of all different types including a Pint with my little cheap Chinese Jelly phone with no problem. As matter of fact my range is 15-20ft or better on everything??? Just a thought. Plus that board comes with the led battery level sensor. As far as speed goes...who cares? If people stop looking at their phones and slow down, There probably would be no noes dives, push back problems and no need for training wheels. I don't think a self balancing one wheeled bidirectional skateboard was made for speed anyway. I got a couple VERY fast dowhill boards that have no motors that are made for speed if the cohones are there. They scare the crap out me .... But seriouly if anyone wants to sell me one cheap , let me know. I would love to have one. I could leave my stupid phone at phone at home. I love everything about the Pint just as is. Maybe they will come up with a new wamy jammy board soon any how. Y'all try to have fun and maybe chill a bit eh? LOL

I really like my DJI Spark. It's maybe not the cheapest but probably the best easiest , least expensive flying "follow me" drone I've ever seen or used. You can hand launch and land with no remote. You should consider small no matter, to stay under FAA guidelines. I have been doing RC and lots of drone stuff for a long time. Things are getting complicated these days. Also small attracts less attention and reduces chances of hurting someone. Goodluck
