    Horn for 96v battery(24s)

    I remember a while ago, tested a 12v pickup truck horn and initial current draw is around 120w. I'm guessing it would be the same or close to the ones I'll use. To simplify further, will use instead 1 of the onboard switching psu that I'll use for charging. Diagram shows in "charging" mode...

    Horn for 96v battery(24s)

    Good point. I already have 2 48v horns. I opted to use (2) 20v laptop psu wired in series switched on the output side, for a combined power output of 180 watts to power them. Each Fiamm horn draws about 1.5A, both is 3A and would be too high for the switch. Trying not to use a relay as...

    Sur-Ron - New Mid drive Bike

    I second and it's street legal! Would be nice if the pack is a bit bigger(>20%) for more range... thinking if it's practical to add more batteries under the seat and use the same bms - i.e. by using thick parallel wires to connect the extra cells.

    bluetooth BMS?

    Thanx guys! I usually start balancing when a cell hits 4V. So, it can balance up to 24s, I don't see any pc connectivity option; I guess it's not supported.

    A2B Metro restoration / modification - Fechter's first Ebike

    Update on the dimmer I posted a few months ago, it works at 12V and 20V. Dimming is tricky to adjust, takes about 2-4 seconds to dim/brighten and I was able to use only 2 brightness settings. When connected to 3 led headlights at 20V, power output is: Dim - 9W Full - 28W Since the amp draw is...

    bluetooth BMS?

    Reading the posts from a few months back, looks like it's usable except the lousy english app. Concerning reliability, so far how many miles have you guys road tested this bms? What's the max # of cells it can display on the lcd screen? I only see 18 on the seller page. Does the "Automatic...

    The ebike parts designing thread with CAD/CAM

    Thanks guys. Using Autodesk Inventor Pro and still learning the ropes... Looking if there is some kind of "Auto Trace" function in the program after inserting the scanned image in the sketch work area. If none, will just have to manually "trace" using lines, arcs, fillets, etc. It's showing...

    Active pre-charge/inrush control

    I may just go all fets because of the smaller density compared to contactor + dc-dc + precharge circuit combination. The Toshiba TK72E12N1,S1X fet you mentioned earlier looks like a better choice and has come down in price. It's $1.86 if you buy 10pcs in Mouser...

    Active pre-charge/inrush control

    Thanks to Jeremy and Richard, my pre-charge circuit lasted for years until I lost it. Now for my present build, I need a precharge circuit for 100V, 180A. I can still use IRFB4115s but will need to change the board layout - more fets, heatsink. What if to just use a DPDT switch wired to a...

    4 wire throttle

    Got the wires sorted. Didn't bother opening it(not easy without cracking the plastic clips). I'm not connecting the crappy meter. Red = 5v Blue = Gnd Green = throttle signal output Yellow = battery pack voltage
