Lead-acid Battery Sag---Log

Sooooooooo.... I did a little log this evening on the bike. Just wanted to see how bad the battery sag actually is. Here you go:

Click on picture to see it all, its too wide.

Brown=Volts
Green=kmh/speed
Purple=Amps

The graph is so jumpy because I go on fast down a straight, up the hill, turn on the hill, down the hill and so on.

Looks like when I accelerate the batteries sag 20 volts.

Logger + Cycle analyst Done

So this morning my cycle analyst arrived. High current version. Here are some photos of the insides and hooked up to the logger. Pretty easy install. Logged data well too. I tested with 2 9v batteries in series haha. I also Sealed the logger and cycle analyst for the wellington weather lol.



Plus, how to connect the logger to the computer to charge and the settings.






Yes that it a verti-go in the background :D :D

Parts Update

I have received so many parcels over the past few weeks it's unbelievable... But totally awesome.
I got my order from sparkfun and have done the Data Logger... I only have to wire it up to the cycle analyst, when that arrives tommorrow. I've used the Logomatic from sparkfun. And 2 of their 3.7v 900mah Lipo Batts in parallel (were on sale for $5 each). With a female usb connector. I think I will move this further in.

I have got loads of other parts... (Also Got an Arduino kit) Connectors for hall sensors motor/controller, connector for cycle analyst/logger, Flasher relay, Polymorph Thermoplastic, 2 Way Alarm, Mirrors and mounts, switch blocks, Tail light, indicators and load resistors, headlight, new front brake and bleeding kit, Koso Digital speedo.


Btw... Was photoshopped in a rush, so mind the rough edges...

Polymorph Is a thermoplastic in which melts at around 60 C. You can put it into boiling water and it will melt, then you can easily mould it or make a mount with it. I will be using it for making mounts and stuff. The alarm will be useful, because I don't want this baby stolen! And all the awesome LED lights, besides the headlight.

Soon arriving will be the eBay volt/amp meter, cycle analyst and 2 Rfid kits.. More info on this stuff when they arrive. I will be using the Rfid reader as ignition, so instead of a key I would just swipe the tag over it and I may have a removable key switch(as in the key can be left in a position and taken out), so I can set it on with the key, but not start or use the bike. Basically so I can use the rfid reader.Once swiped the reader sends out a short pulse so I think I need to wire in a relay to it. We'll see when it's here.
More photos when more stuff arrives.
