Battery placement for trail fatbike

[jonas242]

Hello!
I'm about to attach a bbshd to a fatbike and was thinking on where to place the battery. I guess a triangle frame bag would be the most sturdy option but I pref the looks of bottle cage cage batteries like hailong. I would appreciate any input on wether it's a good id to use a frame bottle mounted battery around 5kg on a bike that will be doing a fair amount of bumpy trail rides. I was planning on using a triple bob or a "super shark" battery for better attachment on the frame but I'm still concern that it might rattle to pieces or fall off.

Im looking for my picture but…

I used a triangle bag from EM3EV and it had internal straps. I hung the battery from the top of the bag with the included foam padding between the top tub, triangle bag cloth, and battery. Secure and free floating essentially. There are some smaller top tube bags that would accomplish the same thing. Revelate makes superior bike packs.

BTW I use a soldering iron to carefully melt a hole/port and a grommet to seal the edges. (or a careful black RTV fix)

Thanks for the info. The bag looks better than the ones i have seen so far but I would still like to have a bottle cage frame mount if it's possible. Is there anybody out there who is using a frame mounted hailong battery on a trail bike used off road? I've seen lots of pics of converted mtbs with this solution. I can't believe that nobody is using the bike for trail riding?

You realize Hailong is just the name of a case? Hailong case 52v batteries are typically glued cells with no cell separation. Not good !
