    thank You ! :) would voltage come into play at all ? Like comparing a 48 volt to a 52 volt on the BSHD ?
    sorry to ask so many questions but funds are not unlimited and I am trying to see if Your battery , the shark, would at least be better , range wise to the one I already have . I have a rear rack mount one that is 48 volt . It claims 17.5 AH and OMG this thing is a lead weight
    Your Shark is lighter weight , better made , and uses higher quality cells . I get about 35 miles out of it . quality of my pack is laughable ( nebie here live and learn)
    Zhuoneng 2500 mAr 91 peice cells at a claimed 17.5 ah

    Sure if you can measure what the average watthour per mile your system uses. For example if you are using 30wh/mi and comparing that to a Wolf with 700wh then that would be 700 / 30 = 23.3 miles. Or if you were using a Dire Wolf 1100 / 30 = 36.6 miles.

    This is a estimate please keep in mind, and will vary a lot. If you use a fair amount of pedal assist your numbers could be more, or if you use a system that pulls a lot of current your numbers could be less

    60A controllers do not pull anywhere near 60A continuously, that is peak current. But yes if you did continuously pull higher than whatever a BMS is continuously rated for, it would trip the BMS. On overcurrent protection you might just need to unplug the battery and plug it back in again, though with some BMS you might need to charge it to reset it.

    Question on the Luna Wolf V2 Battery Pack and how the BMS works. I have a 60A controller...if I exceed the "50A continuous" rating for too long, does the BMS have a "circuit breaker" that will protect it? Thanks

    Glad to hear you were able to make it fit!

    Well in the end it was a challenge fitting the Wolf Pack in between the top & bottom tubes on the magnetic mounting plate from Luna. I installed four 5 mm Rivnuts for strength in the middle of the bottom tube. Installing the magnetic mounting plate i put two washers on the outside two rivnuts between the frame and the plate to accommodate for the curve of the bottom tube and reinforce the support. After trying unsuccessfully to mount the battery to the magnetic plate when centered, I unscrewed the 5mm bolts and moved the bracket down the tube a bit to allow for the last bit of space necessary to wrestle it in place. Once the battery is almost able to make it over the ledge of the track I just pressed the top of the mounting plate down (i.e. temporarily bending it) and it clicked into place. Then I pushed the battery down to where it is now and it isn't going anywhere soon. :-)

    The bonus is that someone cannot steal this battery without a lot of work. Thanks for your help Paxtana!

    Yeah with those tight spots there's a bit of a trick to it. Usually centering the lower portion onto the mount first, then positioning the top in. Then when you remove it doing that in opposite where you pull out the bottom portion first then the top portion. Takes a little getting used to. My bike has less clearance than that and I can do it, though to be fair in my bike I have the battery with the connectors facing downward rather than upward and I'm not sure how that would affect removal procedure on a tight space. I'd bet you could do it though.

    Or maybe on the underside, especially if you use the no drill mounts so you can experiment with it. Sort of like in the pic below

    Nice thing about that is a lower center of gravity as well. Can be harder on bikes like in this pic because the suspension could compress on that front fork and potentially hit the battery if you don't know how far it can compress, but for a bike like yours with no suspension on the fork that is not an issue. Maybe something to think about if you run into an issue. Good luck!

    I am most concerned with the clearance down by where my hand is in the picture. When I simulate dismounting the battery, it looks pretty tight when the battery is up on an angle. I think I will take your advice and mount it temporarily with zip ties or hose clamps to check before drilling.

    There are no existing mounts so rivnuts are necessary for the permanent Luna magnetic mount. I am trying to make it hard to steal the battery, so I was thinking of creating a stainless cradle that bolts into the underside of the top tube where near the supporting bracket is near the steerer tube, secured with a Penta Pin security bolt. That way you could not twist the battery side to side to dismount it without having a proper tool. It would also double as some support should one of the rivets give out. Just a thought.

    Looks very doable! Seems to me you got several options. Those mounts may work, if that's a bit tight you could mount it without the mount using cable ties if you don't need it to be removable, you could also probably mount it on the top tube or on the underside of the downtube, assuming you reinforce it.

    Paxtana, Thanks for the option with the hose clamps

    Here's how it fits in the frame without the mounting bracket

    Are you sure you have to drill rivnuts? You might take this approach, then you can just move the mounts around. It adds a few millimeters but worst case you could use this to get the pack centered then add the rivnuts once you got it where you want it https://lunacycle.com/no-drill-battery-mount-kit/

    Thank you Paxtana. The reason I ask is that I have to drill rivuts and I'd rather not drill if it won't work. It appears I have about 1/2" to 5/8" clearance from the top bar. I'll take a picture and send it.

    You don't really need much in the way of top clearance, certainly less compared to other hard case batteries since you don't slide it upward you just tilt it to the side.

    I received my BBHSD kit with Wolf Pack battery and am starting to plan the build on my wife's Townie. The Wolf V2 w/MJ1's is going on my wife's Townie and I am concerned about clearance between the two curved down-tubes. The battery seems to fit okay in theory, but how much clearance on top of the battery is necessary to remove the battery from the V2 magnetic mounts? I noticed from the Luna videos you peel it off side to side / diagonally. Any advice would be appreciated. Should I send pictures? Thanks!
