    A Collection of Power Supplies and Charging Solutions

    Yep, got me there... Hadn't thought of odd #'s of packs. I considered on board when making decisions about my bike but I'm in a condo and with no power @ my parking stall it would actually be more hassle bringing the bike inside to charge it than pulling out the packs and taking them upstairs...

    A Collection of Power Supplies and Charging Solutions

    By the time I was investing the time to parallel harness that many batts, I'd do series/parallel and take full advantage of the charger... You hit the problem again @ anything>4s though and that's what pisses me off as someone who owns two of the damned things. They should be internally isolated...

    A Collection of Power Supplies and Charging Solutions

    To each their own I suppose... I like my spliced balance taps just fine. It's a one time job if you think ahead a little and you've got a harness that will serve as long as your bike does. I Never use more than about 2/3 of my pack on the bike and I don't peak the cells... I admit, they've...

    A Collection of Power Supplies and Charging Solutions

    If you're into big batts and fast charging it's hard to beat the powerlab 8's I've got two of those I run off server power supplies in series. They're great for shear power and fast balancing (1344watts and they can push up to 3 or 4 amps to a low cell while the bulk charge is going on as...

    DC-DC conveter question

    Not to be critical either, but have you considered how many conversions you're going through when you run a laptop.... Off a laptop power supply, that's running off an inverter, that's pulling 12V from a regulator, that's powered from your 48V battery? I'd be tempted to try making up a second...

    Noob: DIY Torque Sensor Pedal Assist?

    Never been to SF, but I used to play a lot of Crazy Taxi and I've seen Mrs. Doubtfire too many times.... Based on that and my limited experience I'd want all of 1000watts for those hills... I live in the prairies and find spots where my set up bursts 2000 all the time. (I'm pedaling with smaller...

    DC-DC conveter question

    Yep There are devices out there that will allow you to parallel converters without having to match their output voltage exactly. I know they exist because we use them in RC so we can carry redundant reciever packs in our planes. Whenever the sources are off a few mV it pulls from the higher V...

    DC-DC conveter question

    What are you trying to run? If it's just a number of small automotive accessories then I think your best bet might be 15v laptop power supplies. I haven't done this myself yet, just discovered the idea in Teklectic's CA3 manual. I'll be posting my success/failure in my thread in the next couple...

    Noob: DIY Torque Sensor Pedal Assist?

    I'm very happy with my THUN/cycle analyst V3 set up so far. Way more flexible and powerful than the bionx for the same money. If I'm being captain obvious here, you're aware of all that and what you're looking for is a more home grown torque sensor/control system then I can't offer much, but I...

    Pre Charge Resistor Very Hot When Hooked Up

    Yes, those are the ones, I've used them on 14s rc planes and now my bike at the same voltage no problems so far.

    Hub for a 75v battery

    I'd say that's a lot of battery unless you're trying to build a quasi-dirt-bike or something that gets you out in front of sports cars when the light turns green. If this is your first venture into electric vehicles I'd spend some more time reading or talking to people who have experience...

    Pre Charge Resistor Very Hot When Hooked Up

    Don't know what the forum rules are for posting product links so I won't but if you check the popular Chinese hobby distributors at least one offers bullet connectors with good isolation shrouds and resistors built into the tips of the male ends so that you just touch the tip for a few seconds...

    Should I be disconnecting the Anderson or the bullets?

    If your bullets are getting loose stick a small screwdriver down the center of the male end and give it a little wiggle (don't go crazy, they'll break or be too hard to plug in again) and they'll be tight again for MANY connections. Having said that I'd stick with disconnecting at the...

    upgrade complete whats next?

    Almost 50 with a wife of 70.... Not sure how much, if any, of this to take seriously it made me laugh too when I noted you explaining how it's not usually the jumping part that hurts lol, I agree! Few people manage to break bones before impact.

    What do you suggest for the best feeling pedal assist?

    I've only got experience with a THUN torque sensor/CA3 but for what it's worth I cannot imagine that a bionx has anything on it... With a caveat. You have to be willing to play with the settings (there are many) to get the response you want. I'm using the system in a handcycle where I tend to...

    Cycle Analyst V3 preview and first beta release

    An on the fly auxilliary pot display might be a nice addition to the CA3 monitor screens so that one would know at-a-glance what the pot was set at... In my case I'd like to use it to know what level assist is set at. 0-100% would suffice, but it'd be awesome if it would display the actual...

    Cycle Analyst V3 preview and first beta release

    Just wanted to post up a thanks! Got a chance to take the bike out for a quick run just now after switching the pole count to 4 (your recommendation had been just about dead on, the average pedal RPM from the previous ride was 55.9) the bike is a completely different animal I can get assist...

    Cycle Analyst V3 preview and first beta release

    That is a great idea! Not hard to tell you're more than just passing familiar with this system. I have modified the throttle, turns out that if you don't have O-rings a couple zip ties are enough friction to work as well :wink: Due to the nature of how those handles and cranks move while...
