I have a Zoom 1100DH Basically the upgrade to that, I got it direct from supplier for around $220 US about a year ago, so far so good. It is no Rockshox so some elements of the build quality leave about to be desired ( like slightly lose dampning adjusters ) the other issue is that replacement...

Hey, The build looks great with the bomber :D

Very impressed by the quality thus far. I'm interested in an Alu frame build sometime aswell, What grade did you choose, for the tubes what diameter n wall thickness ?

Thanks guys I will definitely make a post in that suggested forum and Im emailing the guys at victron as we speak. Just to give you guys a look at the project if u would ilike, Ive attached a few photos. This is the third prototype, styling losely based on the cafe racer n board track racer...

Good question, Im looking for a unit to convert DC to conventional AC (120V single phase, 60Hz) Im looking to be able to use the battery pack to power basic l load appliances hence a max of 1000W would be great. This inverter ideally should be pure sine wave however modified sine is ok aswell...

Hmm, The current battery pack is a 60V Lifepo4 pack, which is at 73V when fully chargerd, Id need a DC controller which can atleast feed 72V to the BMS for these guys to charge. Essentially I'd love to have a BMS designed that can integrate the solarcharging for the battery.Thanks for the input tho

Hi guys, I'm working with a team to develop a multifunctional battery pack which can used for an e-bike or as power supply for general electronics. To do this I need a custom designed battery management system which allows this lithium pack to solar charge (90V 5A max DC input ) and more...

Just an update, I checked the to determine the cell number in the series which was dead. The very first cell in the series is very dead, of course this is also the cell which DIDNOT have a signal wire for the BM, I connected this first cell to Battery negative without a bms signal wire. I...

Hi guys, I put my ebike to charge this weekend for 2 hours and returned to the smell of something burning :S. I rushed and disconnected the charger and checked on the pack. No fire or smoke (phew) But the BMS was too hott to touch :S. I assumed that it was trying to do something but failing so...

Hey guys, Im looking to do my own arrangement for my 16S Lifepo battery pack. It came from asian-resources.com all wrapped in duct tape using 40152 cells as requesting in a cubic shape 4X4. Now to slim down the width of my housing I wanna do it in a cuboid shape 8X2 where I will place 8 cells...

The battery came with a BMS located outside the the pack in a box. a 48V 30A BMsS is what I requested.. have yet to confirm. The pack was purchased on special order from asian-resources.com. It looks just like this, with a 4A charger

Thanks for the advice guys, this lifepo4 pack cost me some serious money so i just wanna make sure it lasts s. Ill start to break it in over the wkend

I finally got my first Lithium pack :D :D :D. A generic LiFePO4 48V 15ah pack made using 16 40152 cells. I brought it home atd the first thing I did was to cutthrough the duct tape and take a look to confirm the cells and the wiring. Next I checked the voltage, around 51V and then checked...

You guys are correct its not the axel, the correct thing to call it is the cover. You say that cover is made of aluminum ?? If so I can buy one of those alumnium freewheel adapter and have a aluminum welding friend to tack it onto the cover

Hey guys, I have one of those old conhis rear motors with the left hand free wheel thread of course I used a freewheel disc brake adapter like this one http://www.bicycledesigner.com/bike-parts/bicycle-brake/disc-brake-adapter---free-or-flip-flip-hub.html and the threads are complete shit now...
