Here is the BMS diagram I am using lets see if this thing works this is 10s instead of 13s but close enough

Ok so I threw the battery together real quick and I also took the other battery out of the bike to make room, here are the pics

13s 17ah battery

Frame nice and dirty just the way I like it! A little rust already forming! love cheap steel
Image
Here is the old setup, the new setup is going to be a much tighter fit, lets hope it all goes in
Image
Had to move the controller for now
Image
Used two pieces of 16awg wire twisted together for the series connections this pack will likely be drawing 15a most of its life if it works
Image
Quickly soldered them all
Image
put a 12awg turnigy negative on
Image
attached it to the BMS
Image
then another that will power the controller
Image
Put a 12awg positive leading to my controller also
Image
soldered all the BMS balance leads
Image
lightly taped things away from one another hoping to protect against shorts
Image
decided to put the bms on the end since the frame is kinda skinny. This will likely be on the top of the frame near the key switch when installed
Image
neaten up some of the wiring (im no perfectionist)
Image
need to add a switch to turn the pack on
Image
this loop turns the pack on when you short it
Image
OMG it actually puts out voltage!
Image
forgot to solder the charger negative so threw that in real quick
Image
Looks like its just about done
Image
grabbed the charger I was using for 12s and adjusted the pot to put out 54.4v should be good I think
Image

Now I just have to cram it all in the frame and hope it doesn't blow up!

So this was not the most fun thing ive done in a while...but the battery actually fit in the frame. It was a really tight fit and I know what your thinking its because the controller is in the frame, but it is actually because the seat stay bolt heads are hitting the top of the battery.

This is probably not the best mounting option since the bike is going to be top heavy, but I did not want to extend the motor wires or move the controller outside the frame...yet

here are the pictures of the process, its not perfect but that the way I like it!

I moved the controller as far as I could, and then attempted to fit the battery in. I found out quickly I had issues
Image
The seat stay bolts are in the way, if I remove them the battery fits...obviously I need them though
Image
Dug thru a old box of quad parts(metric bolts) and found two donors that I cut down with a dremmel tool
Image
I decided to use the washers to not hurt the steel frame with the angle of the beveled flat bolt so I only saved a few millimeters
Image
before bolts were changed
Image
The bottom of the battery is right against the bottom cover but there is a piece of foam in there. It all fit together!
Image
Now I need to figure out what to do with these wires...
Image
random shot of bike, glad its back on its feet
Image
Grabbed a switch to turn the wires on and off
Image
soldered it in
Image
Used some two random quad bushings to protect wires, cut them down a bit
Image
Switch tucked in
Image
now I will have to work on a charging port later
Image
for now it just sticks out! haha
Image
Finally the bike is charging!

So tried to beat the rain home and just barely did. Clocked 13 miles on the new battery setup and it performed excellent! New too speed is almost 10mph faster by adding 3s

Old top speed 23mph with 10s
New top speed 31mph with 13s
Hit 39mph on a good sized downhill
Averages 25mph on uphills

Didnt bother killing the pack since it wasnt fully charged when i left and was not sure if the bms was going to cut out and cause problems. I trusted it and did the trip easily

After a few cycles when the cells are nicely balanced ill try max range im sure its only about 23-25 miles with my normal pedal input

Much nicer running 13s over 10s, 42v is just not fast enough to get yourself out of harms way at times. But with 13s you got to be careful on the downhills you build speed fast!

So today I wanted to test the battery a bit more and unfortunately I got it to cut out power. I kept it full throttle the entire ride and made it about 9 miles and the BMS shut the pack down. I was pretty scared since I was still atleast 3 miles from my work even though I do carry a charger in my backpack it was starting to rain and getting worse out. Luckily I cycled the BMS switch and key on the bike and it came back to life and let me baby the throttle enough to get to work at about 22mph. which is usually top speed on 10s

so the battery may be even weaker than I thought. But it is only 4p pack of 2c cells. Also if I used 5p in parallel the battery wouldn't have fit into the frame unless I modify the rear seat stay bolts and move the controller

this will have to do for now, I will report any issues

Why are you opposed to puttingt the controller on the underside of the frame.

Im not opposed to it ive had it there before. I dont have a large enough battery for that to matter tho, and nothing overheats at 20a...why go thru the hassle of wires hanging outside? Then the bottom cover is also much harder to open and close. Have you owned one of these frames?

I like being able to open the hood quick to do maintenance, and i like no wires hanging out i guess.

When i closed up the Futr beta i never wanted to open it back up, it was a nightmare of wires in tight spaces crammed next to a battery.

If i ever get a larger battery though i will certainly move the controller outside. Batteries are too expensive for me to consider buying, so i build what i got kicking around.

Great Build thread, Been eyeing up the same frame for my next build, glad to see the geometry kinks were worked out in the end. Did you ever think of swapping the bolts out to brass to see if they blend in with the gold better?

That's actually a really good idea, when these oxidize a bit more I may do this

Does anyone know the pinout of the S-LCD1 Ebike meter from BMS battery? I want to see if I can install it on my bike, it says it only works with S type controllers but I have a em3ev 3 speed controller so I may be able to make it work

Image
I have one that says its 24/36v rated but on the website they say up to 48v? So im not sure if it will work already

it has 5 wires on it

red: positive
black: negative
blue:
green: may turns the system on?
yellow:

I found a wiring diagram that says its only 36v so this may be a waste of time since I run 13s now...

but it says
VB+: red
Control: blue
GND: black
Data1: green
Data2: yellow

but what the heck is control and data1 and data2??

Really liking this build! You've done some nice work turning an ugly duckling frame and a bunch of mostly used parts into a bike that looks (and probably rides) better than bikes that cost a LOT more.

It looks like there's a lot of room above the shock inside the sub-seat frame. Do you think there'd be room to put a small controller (eg. phaserunner) in there? I'm considering this frame and I like how clean it looks with the controller hidden.

Next time I have money to waste on Ebikes I want to buy a phase runner and another Cycle satiator(mine was run over by a fork truck)
that's $600 plus shipping I will be saving my pennies!

Yes a phase runner or small Kelly with absolutely fit in the shock upper

I guess I need to save my $$ better since I was at the bike shop I picked up a set of new pedals. I haven't bought a nice set of pedals in over a decade so why not! I usually buy the $8 ebay sets but these pedals caught my attention so I needed to have them!

thanks I have fun with the bike commuting with ease, I obviously like more power...but do not need it for this bike

I choose riding a bike with pedals as opposed to my mopeds when I have a choice
