Since I purchased this 48V 15AH I can definitely say that it changed the my job.
After the purchase I was not sure I will be happy with the results, but I could
feel the difference right away. My bike had more power and lasted me way longer than before.
The build quality is perfect with no compromises. I can say it is a safe bet
for everyone wanting to change the old battery of their bike and bring it back to
life. Try it ! Definitely a life changer !

I’ve riding the Cross E-BIKE 250W – 36V10.5A and all I can say is wow !
It is very nice to ride and with this battery I can travel around my home city
whole day with no issues. I can definitely say this is a very nice budget option
starting as a courier. Don’t just take my word for it, try it yourself and you
will be amazed.
