Thanks a lot for your support!!! :mrgreen:

Hej guys! After killing my 18-Fet lyen controller twice, I started thinking about buying a new one (budget AROUND 300$, no problem if cheaper :P). My setup: Samsung 25R (22S8P) 92,4VDC Besstech BMS (max. 80A) Cromotor V2 (Hall, 18x4, max 180A phase current) bike wheel size: 17" moped...

Hahahaha Thanks izeman! :D Yeah for sure, I will visit you with the bike for a nice trip. But onestly I like the whining sound! : D I dont have the feeling getting rid of it ... Mounting was no problem! I mount the fets with 3 turns clockwise to the aluminium heatsink so that they have the...

My E-Power Puch Maxi WMpkaPUfeow

sunday ride with the original 18 FET infineon controller: WMpkaPUfeow

Big thanks to Ron for taking time and writing this nice article on electricbike.com, I'm honoured getting my project on this awesome side. Thank you maddin for your support! I got 20 of Ti's Fets as samples! :D They arrived yesterday, so I started upgrading my lyen controller. I started by...

Dude! Very, very nice build! I love the upside down fork. The whole bike looks very good, why dont you put the batteries into the fuel tank? :P Please keep us up to date! :mrgreen:

@ maddin: Carbon foil sounds great, I will think about it You are defenitely right, every FET has its thermal limits and I passed them :D So I killed a IRF4110 from one of the three Phases ... I spend some time for finding "better" one, but thats not that easy... Because you are limited to...

Thanks guys for the positive feedback! This bike wouldnt every be finished without the help of my mechanical genius/ welder ;) I'm going to cut a short video of my ride from last weekend, I hope i can publish it till sunday. Next step will be finding a cool design for the side covers and the...

Hey guys! Thanks for your support! I already solved the problem :) The first things I checked were the max. ratings which are provided by the CA, there I found out that max. peak current was 109A, so I upadated the battery current to 85A and now I dont have any problems. I am onest! Driving at...

Block Time is set to 0 since the beginning of the bike build :) Do you know other reasons which can influence the current measurement of the CA? I havent changed the Shunt, which is on TOP /Bottom Layer @ Ground. Thanxs

Thanks a lot :) I will think about it :D @ izeman: Maximum speed are 85km/h (100%). I get a total Wattage between 7 - 8 kw. I dont understand the following situation: stillstand, full charged (92.4VDC) pulling full throttle --> ??BMS?? shuts down --> I can see the Voltage on the CA...

@ SamD Thanks a lot! ;) My bike is ready to run! :D I have already collected 130km in 3 days, but temperatrure isnt very pleasant out there! I am going to continue step by step. ... After soldering together the bms wires, I found out that they were a waaay too long, so started from the...

Hej guys I got in troubles ... Today I put together my setup (Samsung R25 22S8P, Lyen 18 Fet, 22S80A bms, cromotor v2). I built myself a litte test station for my bike, to check the new battery setup (92,4V full charged) ... So I put everything together and played around with the throttle...

Your welcome, my friend! Last week I had enough time for finishing the Infineon controller... (black coated, R12 mod, 8AWG, 1000uF Rubicon caps, strengthened circuit path, changed connectors (JST), new heat transfer paste, programming..) Next step were the side covers for the BMS and...
