@DonCox it’s for my 2009 CRF 250 but frame should be the same from 2006-2009 CRF 250 I used also the available space inside the Gas Tank

@fsfs I know exactly the video you are talking about after watching that I also decided to go with the P45B Cells. here is what I just Orderd at Amorge: 22S13P Open Discharge (BMS only for charging up to 50A) Metal Case

@unluckypanda haha I have no idea what these things are called xD I just ran through the local Hardware Store and looked for something that has nuts or screws attached and mounts on something round so I ended up in the Plumbing corner and found these: as I was not smart enough to measure the...

Little update on the Project Build Costs now that I am almost done: E-MX Bike Build Parts (include Shipping Costs plus Tax and Toll to Germany) Money out Money in Honda CRF 250 R 2009 1.800,00 € Sold the CRF 250 Engine 700 €...

Today is the day I just placed my Order at Amorge :) so my final Battery Shape for the Honda CRF 250 2009 (same frame from 2006-2009) is: Molicel P45B 22S13P 81.4V 58.5AH (Optional 20S14P 72V 63AH but I went with 22S) Metal Casing Open Discharge (BMS only for Charging) QS10 Plug for Discharge...

@unluckypanda I was at the same point as you now. I took the time to watch this Video and try to learn everything about the cells along the way (thats a freaking 4H+ Video xD) but the guy put a lot of effort into this: but after watching this I sattled on the Molicel P45B as it gives me the...

@bayodome I am a super chill amateur I just wanna have fun with the buddys on a saturday at the track. I don´t do trails only MX Tracks With the Bike Build I have (same Controller same Motor) and a 72V 55AH Battery a dude with a bit better skill then me was able to ride 4x 15 min at the track...

@Theo yep that Idea was never really an option for me as I am not building the Battery myself, I doubt Amorge can do that. with one BMS connected to two battery housings or even worse two bms. In the end the plan was to have it swappable slide in and out from the top. the Plastics and the Tank...

so lets continue.... TX Race Restyle Plastic Kit is awesome: Controller fints just perfect in the Airbox: Cables will be fed through from below through the hole from the Carb Side. Battery still gives me a super hard time... to Fit anything in there the TOP motor Mount Bracket needed to...

@bayodome at least in my situation I have to stick to max 81v battery’s since my x-9000 controller can only handle up to 95v and a fully charged 88v ewatt battery has up to 104v so that crashes the limit there should be a 3sul something and a big fardriver controller that are capable of handling...

thanks to all of you who contributed knowledge and info I guess I made my mind now. not saying that I have decided on a specific battery yet but I have a plan now that I will follow :) my absolute Dream Battery is this one: EWATT 72v 76AH Pouch Cell Battery Dimensions (mm):225mm x 177mm x...

@bayodome I guess we all agree on that one :) we are just fighting for a few milimeters more to squeeze in the maximum power otherwise we wouldn’t be able to jump anything anyways if we have to flintstone that thing :P

this sizes sound exactly like the Electro & Co eg. eonlithium.com 76v 48ah battery. Also tried to test fit that in the 2009 CRF 250 Frame but zero chance would have to cut away way too much from the frame. so 72v will be enough for me I will see what amorge is able to do maybe also an...

Hi @DonCox , do you know if its possible to ask Amorge for a 40A charge BMS and open Discharge on their batterys?

Hi @bananu7 nice which model year is your CRF? What battery you end up ordering? I ordered so many pipes to make spacers xD the Motor Mount Swingarm side is locked in place into every direction will say its not able to move up down or right left I have one big tube across with inner diameter...

a ton of parts are in now ready for friday to be installed. Plan is to: finally fix the motor in place fix the controller in the Airbox install the new Restyle Plastik Kit to see which areas of the Fule Tank I can cut away so it not gets visible. then take measurements for the max available...

@Theo good points I cannot really check the weight distribution upfront as I am not aware of how much the battery will wight in the end and I have to decide for its place before I can find out about the weight... but in general they are something beween 22-35kg I can maybe place something...

Mounting for the Battery I am playing with the idea of doing it out of 8-10mm Carbon sheets cut to size with large bolts going across to the other side with spacers in between. Saw it on a bike that a company here in Germany (https://www.zweiradsport-brunner.de/) build for a customer: (its a...

Thanks for the input @DonCox (y) I choose the EBMX controller mainly for its easy to use userinterface with bluetooth and the app, to not have to carry a laptop to the track to quickly change something although I think once you find the right settings you no longer have to touch it anyways. I...

@Philip they are acutally very sturdy. They look thinner than they are but once in place with the right screws nothing moves even a milimeter. I have no fear letting 33kw dragging on it
