    Need fuse replacement

    My workbench PC died recently. I traced the problem to a blown fuse in the Coolmax CR-450B power supply. I am assuming for now that the cause was an AC line brownout (I didn't have it on a UPS) so I'd like to just try another fuse for now. The fuse presses into a couple of prongs on the power...

    Want schematic capture and simulation software

    I want to do some analog design and board layout for hobby purposes and am looking for a good set of software tools for schematic capture, SPICE simulation, and board layout. As far as schematic capture and SPICE simulation are concerned, I have tried out the Multisim demo version, Tina-TI, and...

    Balancing eZee Li-Mn battery

    My 36V eZee Li-Mn battery was exhibiting more voltage sag and a noticeable loss of capacity lately. I e-mailed Justin at ebikes.ca asking if he sold replacement Phylion cells. He doesn't sell individual cells but suggested that I check the cell voltages and try to balance them. Here is my...

    Stripping wire with teflon insulation

    I have found PTFE (polytetrafluoroethylene, DuPont brand name Teflon) insulated stranded wire difficult to strip using the kind of wire strippers you find at hardware or auto parts stores. It's easy to nick the wires, and sometimes the insulation shreds into strips rather than coming off...

    LED bike lights with DC-DC installed

    I just received LED headlight and taillight with integraged DC-to-DC converters from ebikes.ca. I didn't care much for the default installation strategy of strapping them to handlebar and seatpost using wire ties. I happened to have a spare Cateye Enduro8 speedometer mounting bracket that I...

    How to tighten up CA speed limit?

    Hi all, I have a 72V 35A analog speed controller and CA v2.0 from ebikes.ca. I am using a 56V Milwaukee 10.4Ah Li-Mn battery configuration (2s4p) and EVTECH BMC rear hub motor. I want to travel at a constant 20mph on level roads and up modest inclines. I also want to continue to make use...

    NiMH pack and controller left on all night

    A colleage of mine left the controller on his Ezip bike on all night. He later tried to charge up his 24V NiMH pack and it got very warm. The pack is inside his bike frame and he felt the heat through the frame. He doesn't know which of the cells were getting hot. He has asked me for advice and...

    Joey's Ebike #2

    This started out as a simple project but has turned into quite a saga. I have decided to document the experience as well as some lessons learned. My original goal was to build an e-bike starting with (1) a steel-framed hardtail with a decent front suspension, (2) a BMC rear hub motor from...

I have searched the forum for information, but everthing I found begins after the step I am needing to complete. Here is where I'm...

    Charger/balancer for 4sXp LiFePO pack Desired

    I perceive that there is a dichotomy in LiFePO combined balancer and charger design where a potentially useful middle ground may exist. At one extreme is the Voltphreak single-cell charger approach for which, for example, a dozen individual units are required to charge and effectively balance a...

    Need help with CA settings

    I have a 24-72V 35A analog clyte controller and CA from ebikes.ca, and EV Tech BMC hub motor with shortened wiring. I have a 36V LiFEPO4 pack on order but until it arrives, I want to use a 36V Li-Mn battery pack with internal BMS from an eZee hub kit to power the clyte controller and BMC motor...

    Where is Puma motor at Team Hybrid?

    I just visited the armybikes.com and teamhybrid.co.uk websites. There are some significant changes since the last time I visited them. I couldn't find the Puma hub motor anywhere. Have they given up on it? -- Joey
