As the Hub Motor Turns and the Lipo Fire Burns. 36V AmpFlow / 5 horses.
My keyboard broke. On screen sucks. Some people are just dumb. There is good excuses for it but not when you run an electronics store. Glimmers. Where I went before looking for switches awhile back. Dude don’t know about pots either. Really stupid! Sold me piece of shit. Told him 4.5V to 0V throttle. Need it to be variable from 0 to max. $4 for that. About 1500 to 4200 rpm with the little motor I would say. see new pot.
No way I can run it. big motor would start at 1000rpm. Not good! Got to go all the way to Radio Shack to get one like I had. Dude better give me the money back or I will punch him in the face. He is an ignoramus.
Took controller out of case to check for something burnt but looked good and could not get back together. Waterproof now! See controller No new controller! Could have used that $38 this month. Bullshit shipping from China not free shipping! If a pot don’t work I ordered it for nothing. Be glad to trade it for something if pot don’t work.
I want to get a soldering kit and good connectors plus shrink wrap and a couple more $15 Chinese controllers. Solder on connectors for motor, power and throttle. Three connectors and carry an extra controller and pot and a little tool kit with a led light, scissors and zip ties. The pot will have the plug soldered on it also and a burnt controller or pot could be changed and the bike up an running in a jiffy.
The Cheap 36V Chinese controller I got now held up good. Was on the Currie and wired up at least 20 times since that old guy who first upgraded the Currie from 24 to 36V about two years ago now. Never use a fuse since either. see controller.
If 24V @ 20Ah is good for 20mph at 1C discharge than 36V @ 20Ah is good for 25mph at 1C discharge. It may be the last two SLAs I ever order next month. Only way I would order SLAs again would be if the pair of 8Ah SLAS for $15 free shipping was still available. see SLAs. SLAs are easier to charge and store. Dont need LIPO bags and metal boxes to protect them and the environment.
See terminals and parallel charging. I don’t want to go over 25mph anyway without a new motor sprocket and another motor install for a tighter chain. Runs great at 25mph now though as the videos I did a few pages back show. I am sick of working on it and don’t want to install the new controller now or run LIPO yet. I just want to hook up a pot and run it at 36V and next month upgrade to 20 Ah.
That thing would go 30mph easily at 49.2V but if the chain came off going that fast it may not end well. 39.6V is enough for now. I probably will keep it around 20mph tops and mostly about 10 or 15mph. 20mph at 36V has to be easier on the batteries than at 24V.
Parallel charging and terminals show the 4S bricks that will replace the ones Dan sent when the time comes. The left side of parallel charging is the standard way with bullet plugs for running and charging. It requires lots of plugging and unplugging, wear on the plugs. The terminals avoid worn or faulty plugs and even shock via the pre hook up cable. See cable. You could put the two resisters between bullet plugs but I would rather touch the terminals for a second than plug anything in. Much quicker and easier. Charging and running.
For three packs of 4 to 6 SLAs each pack, two foot cables with Bullet connectors on each end would work well hooked to two bullet plugs wired to the terminals. One on each side of the frame with the third pack under the terminals on the back rack. If the balance plugs won’t reach I can put the charger closer to the packs and make the charging cables longer.
I dont parallel charge the packs Dan sent because they were taped off in pairs and need separate charging. With 9 or 12 new SLAs I could charge all at once very easily by hooking three short wires with clips to the end of each charging cable and using the pre hook up cable before each connection first. No plugs involved!
See LIPOs vs SLAs. That is not just a diagram but questions. Please let me know. Those are 5S LIPOs. The problem is there usually is no good deals on them but as you see the voltage compared to three SLAs in series is impressive. It is also perfect for the 36V 3330W Amp Flow motor as 49.2V (two 6S in series)or 4.1 * 12 is way too high.
The big question however is how to combine the packs? I am talking about the balance cables of course. With two, four or eight bricks it is simple with Y balance cables and extenders. Five six & 7 can’t be done though. WHAT other cable will work? Is there a parallel board that will work without the power wires hooked up? If I plug in five or six bricks into this. see board. Bullet plugs gone anyway. The board will plug into the balancer thru an extention.see combined.
That is six 4S or 5S bricks in parallel. Another six will be combined for a second pack to achieve 30Ah @ 32.8V for a 24V motor with 4S bricks. as two SLAs are 26.2V. Perfect for the 24V 900W kit Monster scooter sells for $199. The 36V Amp Flow motor will run 41V and close to 4 kilowatts for an easy 50mph with 5S packs though. Please let me know about 5S bricks, the board and balance cables.. I will be posting this and selling the Magna for money to get a bus to Radio shack. I want my DB. Running. Thanks.

PS. Got a letter today stating I am approved.
Money is coming my way.
I should have the 3330W AmpFlow motor soon. I really need answers to those questions. Also will a spoke sprocket hold up to 5 horsepower ? I am building a bike to go 50mph. Thanks.

PS. again. I just PM LFP. "I will be getting a money settlement soon. Not looking for anything free just a good deal if you know where I can get an FX - 75-5 motor around the first on next year. I want to build a mini Death bike for summer. Please let me know if you get a chance. Thanks. LC. out."
