    2017 Giant Glory 1 with BBSHD

    Hi was wondering if you could give some details of anything that needed to be done on this? I was looking at a 2008 glory 0 to put on a bbshd (will be my second build). First was an easy bolt on to an old cannondale of mine. Dont have much machining abilities and wondering if this is easy to...

    2015 Gen 2?

    With lack of information on people using this I ended up going with the Bafang mid drive unit in mid summer. I have had I think three controller failures on the unit but happy to say it is working well now (I did cut the max current down by one amp on the contoller). It has been quite a bit of...

    BBS02 controller current 25A 48V

    Curious to get some input. Purchased my first BBS02 kit. Had a string of bad controllers. First ran for 40 miles or so. FET Died, probably from my driving in hindsight. Second from another vendor (while I send the first one back) arrives DOA, sent back third works for another 40 miles...

    LIFEPO4 pack:right/wrong way to charge for longevity?

    I thought that was advice for Lipo chemistry. I partially bought the cycle satiator because I thought the claims of increased longevity of 80 percent charging lithium batteries also increased the life only to find out on further inquiry that only applied to lipos. (what is SOC and DOD by the way?)

    LIFEPO4 pack:right/wrong way to charge for longevity?

    Wondering if there is a general good/bad way to maintain an LIFEPO4 battery pack for longevity of cells? Here is what I have: 48V 16s 10Ah 38120S LiFePO4 Headway Battery Pack (with BMS) Cycle Satiator charger (its just plain fun to use...) What is the general philosphy for best pack life (or...

    Problem with LiFePO4 battery bms or charger?

    I left the charger at the beach house, cant get that right now. Voltage was the same as when it was originally supplied to my recollection. The battery is a 16 cell (assuming 8 series/2 parallel). Individual cells all report 3.294 volts and 52.7 across both the charge and run wire

    Problem with LiFePO4 battery bms or charger?

    I opened the battery pack up to look at it. Each cell is balanced and showing 3.294 volts and 52.7 across both the charge and run wire. I forgot the charger out of town, do not have it right now but I could charge through the run cable. Is it safe to assume that the BMS card is bad? Also...

    Problem with LiFePO4 battery bms or charger?

    So far I have verified the charger works. I ran it for an hour on the "run" cable for the battery bypassing the bms. Charge is showing and matching on both the charge set of cables and the run set of cables. I think i cut the charger out at 51 Volts plus or minus. Seems to be something with...

    BBS02 quit working! $%#$%&*

    Blue and yellow test at 10 +/- immediately. Green bounces all over the place, sometimes 40-50k ohm, sometimes 10ths of an ohm and doesnt seem to want to stabilize. Is green considered in this or is this a ground?

    BBS02 quit working! $%#$%&*

    Looking deeper, mechanically I see no issues inside the motor with the gears. The stator seems in very close contact with the rotor though, not sure what tolerances there should be. I need some guidance for checking the MOSFETs and motor if anyone can provide some guidance. I have the three...

    BBS02 quit working! $%#$%&*

    Frank, thank you for your help. Wondering if you can provide a little more guidance here. Which plug is being removed, the main harness or the one with the screen? Is there a map that shows which is the battery connection. I seem to see people refer to the display as the controller...

    BBS02 quit working! $%#$%&*

    I have a 965 also. Apparently there are multiple versions of the same unit. My unit displays a small brake symbol when I grab a brake handle. I do not however show any power consumption data, which is what I wanted when I paid extra for the unit!

    BBS02 quit working! $%#$%&*

    No change. unplugged all and no power output. The sensors are working and you can see on the screen when you grab the brakes also, so I dont think that is the problem. It appears to be getting the correct input.

    Need help with Battery pack that just arrived with kit.

    Thanks they came with the Anderson connectors I think. They looked a little sketchy to me. Have not used those before. Would you just suggest cutting off the RCA from the charger and installing them in its place? I like the hobby king bullet style form my lipo days. Also wondering is it...

    Help with mid drive selection and expectations

    Awesome. Thanks. Can you provide any thoughts on the 500w planetary powered vs chain reduced. Are they close? Same question on the GNG planetary vs BBS02. Heard the old version of the GNG had heat issues, but it appears that they have changed it. If that one just werent so damn shiny......:)

    Help with mid drive selection and expectations

    Thanks very much for the input guys, every little bit gives me some more insight. Im kind of leaning to the Bafang because of relative size, noise level and stealth. Wondering what size chainring you are thinking might work well. The one you showed is only a 42, do you think that is small...
