Product detail

After 48v 15.4Ah fish battery used in 48v e-bikes, clients want longer distance.Also some e-bike DIY are also making small scooters.We have to increase the fish battery again to meet client's requirement.

Then 48v 20.4Ah black fish battery is coming to e-bike world.We used 30A BMS, and changed the discharge fuse.Case all parts are just same as before,only the middle aluminum part are longer.

Because discharge, size and protection are all different, these related accessories must be replaced with higher version.Finally,we even find the lock wire will be melted by the discharge current.

30A discharge fuse has been the highest level, if clients still have fuse melted problem, disconnect with fuse is also a good choice.Besides,make a new fish case mode,add the fuse at the bottom, this is the regular method,but the cost is very high.
