Before choosing a new one, knowing what specifically failed with this one would help find one that won't do that again.
What is the problem the battery pack is having, and under what conditions did it occur?

ebuilder said:Hello,
My first post and just learned about this forum and great to be aboard.
A question please to those that have replaced their BMS on a Hailong shark style battery...in this instance the case is similar....shark style battery case is made by Reention.
Battery cell spec: 21700 Panasonic Tesla cells
14s x 4p = 52v 19.2 amp-hr.
Current BMS is rated at 45 amps
Please note, this BMS has an On/Off switch which wires directly into the battery On/Off rocker switch
I really don't want to do a smart BMS...maybe constrained by limited package size...tight packaging between cells and case bottom plate.
A picture of the failed BMS:

Motor application is Bafang BBSHD with stock controller for now and would like to stay in the 45-50a BMS size range for adequate headroom over the max draw of 30 amps the stock BBSHD is currently programmed for.
Any suggestions where to buy...or a link of a 'reliable' BMS??...which seems like a black hole to a newb like me that hasn't built batteries. If someone has a track record of success with a given supplier or brand/model BMS, this would be a great help.
Thanks very much.
