Thank you for you comprehensive answer. In short, I wasn't sure whether I should wire the speed sensor to ground or +5v. So that's the correct wiring: All the best, Kamil

Thank you for your reply. I am trying to figure out what kind of signal is sent between CA-DP/CA-DPS and CA. I suspect it's analog hall signal, and I am trying to confirm it would work, when I pass +5v via magnet sensor (and produce a pulse that way). Unfortunately, it's not specified on CA...

Hi, I can't find that information. I want to use ordinary magnet speed sensor with my Cycle Analyst 3.1. I think the input pin is ready for hall sensor signal, so I should send +5v pulses from the magnet sensor to make it work. Is that right? Thank you in advance for your help, Kamil

I'll see. I've ordered 45A BMS (180A max). My current scooter pulls max 1kW (20A@48V) and I doubt that 120A... (unless the brushed motor is far less efficient than my BLDC motor)

Hi All, I know it's an old topic but I'm currently planning to build my own battery based on 18650 cells. I wonder, what's the max current being pulled by the scooter in turbo mode. 40A, 50A? Thanks, Kamil

My IMAX can work with 8s. I started by replacing bad cell for new ones but the IMAX balancing does not work (or work, but insufficiently). One or two cells quickly reach max voltage and the other remains ~0.2v lower (I was leaving it overnight but in vain). Discharging is pretty the same but...

It's the battery: http://www.hobbyking.com/hobbyking/store/__14070__ZIPPY_Flightmax_4200mAh_4S1P_30C_LiFePo4_Pack.html I was considering restoring the battery by cycling it but I don't have proper tools for it. I was using stock charger or imax b8+ charger but the progress was so small I gave up.

It was DIY battery with 16x HK Flighmax cells. Two cells were dead. The other are out of balance with 40-80% of nominal capacity.

It was included with dead LiFePO4 battery. I was trying to compare it visually with other units using Google Graphics (it usually works for me), but no luck this time :/

It was purchased 2-3 ago on eBay. The seller was from Isreal (if that matters). I can't find it's exact specs, documentation etc. Anyone recognize it? Thanks

Thank you for reply. I'm considering this "Signalab BMS" (this one, 16S version of this one: http://endless-sphere.com/forums/viewtopic.php?f=14&t=49754). Yes, I'm going to add JST plugs to the existing BMS wires. I have a question concerning Signalab BMS - what happens when the battery is...

Could you suggest one? I'm building a small battery for a lightweight bicycle and I'm looking for a small and reliable BMS (with LVC,LHC and balancing function). Extra features (like diagnostic interface or temperature monitoring etc.) are welcomed. I came across the "Zephyr" BMS but I didn't...
