    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Are you sure you aren't in "Street" mode which limits power? Also, check to see if you have "Experimental" mode set, I needed that to get higher than 250W. I don't know how strong your hub motors are, but I am riding the TSDZ2 on a single speed Surly, and top out at around 36kph, only because I...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    At 3 volts per cell you are at about 10% state of charge. Assuming you've set the resistance values in the controller (your battery internal resistance plus your cable resistance), then I wouldn't go any lower than 42V. I have a similar pack with the Samsung 30Q cells, and am using 44V right...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    I'm not one of the developers, though I do work on a lot of large battery systems. Attached is a quick graph I put together showing the interaction between the three main limiters of power - your current limit, your power limit and your low voltage cutoff limit. In this case, current is...

    Group charger for 3-6 batteries?

    My office recently added a lot of indoor bike parking, which has spawned a big increase in bicycle commuting (great!), and the number of ebikes is going up as well (2 now, and 3 more people are shopping regularly). Instead of having power strips with tons of individual chargers dangling off...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Good news! I agree that the effort to put the common codebase together is worth a little delay - the SW102 sounds like a nice display as well and I'm impressed at the rate the development has gone for it. Even better! If the bootloader/OTA flashing situation is close to being solved them I'm...

    TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

    Just got things running on my small cargo bike with 0.19.0 and the 850C version 0.2.0 (just missed the update). I'm running a 52V battery on a 48V motor, singlespeed drive (42/16T). With mostly stock settings and a few adjustments everything is running quite well! I'm very happy with the...
