EDIT All that power on a Schwinn fatbike? Best put better brakes on the list!
Looks like, looking at the links, he’s in Canada
Goldenmotor, Gary Salo is Canadian.
EM3ev, a UK expat with Chinese factory is an industry leading battery maker.
Both reliable fellas.
The akonasada from Amazon appears to be just another new Chinese trading company, also on Aliexpress. I’d avoid them unless someone has seen or reviewed their builds. They don’t mention which cells are used. Brand names can be meaningless. EM3ev or Grin eBikes.ca, and then Golden Motor would be my choice. My first battery was from EM3ev. It’ll age out before cycling out.
EM3ev wins for me. My shop has them build the batteries, they have D-Powercore Bluetooth Battry Management Systems. Super easy full battery review/data on a smart phone. Making supporting their batteries easypeasy.
25A continuous is fine for a BBSHD. And the cells are GA, capable of much more. Perhaps that’s why the sale. They dumbed the pack down with a lower rated BMS. Making Goldenmotor best suited for 750W BBS02B or hub motor not your BBSHD.
I run and support these,

Recommended Max Discharge Current for each Cell Type of the Em3ev Jumbo Shark 52V Ebike Battery:
- Panasonic PF: ~29A Continuous, 38A Max Burst Current
- Samsung 30Q: ~38A Continuous, 55A Max Burst Current
- LG HG2: ~ 44A Continuous, 55A Max Burst Current
- Samsung 35E: ~25A Continuous, 34A Max Burst Current
Please note we recommend a max of no more than 50A for the BMS. The trip current is set just above 60A.
Note: the cell manufacturers specs are higher than our recommendations above. It will not harm the battery to occasionally discharge at higher levels than our recommendations, but regular, sustained high discharge rates will degrade the battery more quickly and the battery voltage will sag at these high power levels. The Battery BMS is programmed to trip if cell temperatures reach 60degC during discharge and 45degC during charging.
Capacity Specs for each Cell Type of the Em3ev Jumbo Shark 52V Ebike Battery:
- Panasonic PF: 50.4V nominal, 14.3Ah, ~718Whrs.
- Samsung 30Q: 50.4V nominal, 14.8Ah, ~743Whrs.
- LG HG2: 50.4V nominal, 14.8Ah, ~743Whrs.
- Samsung 35E: 50.4V nominal, 17.0Ah, ~857Whrs.
Bottom line! You will want a 30Q or similar cell and a BMS that will put out the higher amperage you’r

BOTTOM LINE. Personally I’d use the Grin Phaserunner. They have a sweet BBSHD setup. Next LG HG2, 30Q or similar spec cell. I’m surprised that you’re considering a BAC style controller and not paying close attention to battery out put. Perhaps you might step back and reconsider some choices. You could hide a Grin Baserunner in a 30Q case. Or since it’s a kitbike? And you are ramping it up think about a hardcase sized 30Q. Shark packs won’t hold 17Ah of high output cells. I run 52V 20Ah Triangle pack on my BBSHD.
