    Blackburn Outpost Elite Frame Bag

    Has anyone used a Blackburn Outpost Elite Frame Bag for 65mm wide batteries? Blackburn advised that the bag is 57mm wide. I'm wondering if I could safely fit a pack about 70-75mm wide by bulging the bag out a bit at the sides?

    Bafang M625 BBSHD 2021 - 3rd Party Options

    Are all CAN devices compatible or only certain ones? Is there a way to use non-CAN 3rd party devices?

    500C Display + 72v Battery?

    The setup I'm looking at has a 72v compatible controller (BAC 855), but the retailer advises that the 750C display is required for 72v. I'm not sure if this is just due to the battery voltage display only going up to 60v on the 500C, or if the 500C will not actually function when connected to a...

    500C Display + 72v Battery?

    Can the 500C display be used to adjust settings when used with a 72v nominal battery? It seems that the 500C can't display volts over 60v, but if I only want to control the motor functions will the 500C work with a high voltage battery?

    Mid-Drive Drivetrains for ~1kw

    Would a geared hub motor suit steep hills with panniers full of groceries? The area close to my house has a couple of big inclines that I can basically only make with the lowest gear on my flat bar road bike.

    Mid-Drive Drivetrains for ~1kw

    iirc plate width on a single speed chain is going to be a bit thicker, perhaps giving the interface a bit more "meat" to wear down before it affects performance? The questions I'd have in that case would be: Over the same no. of km would replacement cogs & chains cost more or less with a...

    Mid-Drive Drivetrains for ~1kw

    In regard to long term running costs & ability to handle power without breaking, are there any clear winners for drivetrains around 750w-1500w? I have been looking into Shimano LinkGlide and Shimano NEXUS Inter-5E. Rohlhoff is out of my budget.

    LiFePo4 15s Charger?

    Yeah, I can't think of any drawbacks of running 15s significant enough to warrant that cost. The motor & controller are happy at the voltage from 15s and it seems that the HLG-xxxh-54A works with 15s.

    LiFePo4 15s Charger?

    No dice. Looks like it's 15s or ~$100 for the extra cells.

    LiFePo4 15s Charger?

    Yeah, definitely. I'm hoping the cell retailer can do a smaller order, otherwise it's going to get a bit expensive. Fingers crossed. Would the extended life be from a shallower DoD? I was wondering how the HLG-xxxH-54A would behave with it's max Vo set to below 58v: would that run CC up to...

    LiFePo4 15s Charger?

    Good idea, I'll shoot them a message and see what they say. Just looking at their web shop shipping is going to roughly double the cost. If I absolutely have to do that I guess that's what I'll have to do ;) I'll be using a BMS.

    LiFePo4 15s Charger?

    Will the PSU overcharge the cells if it's configured to output 54v for 15s? I was planning to add a cheap Volts / Amps display from aliexpress, eg. https://www.aliexpress.com/item/32788030454.html and checking for it to hit 54v / low current and then turning the PSU off. If I can stop charging...

    LiFePo4 15s Charger?

    The Satiator looks great! $600 dollary-doos though :o Could I use the Mean Well HLG-320H-54A for 15s and 16s? It lists the constant current region from 27-54v and an adjustable output range of 49-58v https://www.meanwell-web.com/content/files/pdfs/productPdfs/MW/HLG-320H/HLG-320H-spec.pdf

    LiFePo4 15s Charger?

    Is there an advantage to running 16s vs 15s if the controller + motor + charger work fine with either configuration and the power available with 15s is adequate?

    LiFePo4 15s Charger?

    The cells I bought came only in bulk, in a number divisible by 15 not 16.

    LiFePo4 15s Charger?

    k2 26650 lifepo4 in 15s 8p. I think I've been searching for the wrong thing, I haven't had a lot of luck finding a charger at around ~54v.

    LiFePo4 15s Charger?

    What chargers will work with LiFePo4 in 15s configuration? Will any 54.75v lithium charger work? Thanks!

    new cyclone 3000 w mid-drive kit?

    Can this motor be run with virtual-torque as throttle with stock controller? eg. faster pedal = motor spins faster, slow pedal = motor spins slowly Can I limit the max power & speed? Is there a road / off road mode? Thanks!

    New "TSDZ2 Torque Sensor Central Motor"

    Thank you. So water-resistance can be improved with epoxy on between the inner surface of the two outer-most bearings and the axle? Would the additional bearings increase the life of the sprag clutch that is attached to the large gear? I really like the features of the TSDZ2. I have the skills...
