I found this link looking at Amazon. Has anyone used these cells for an Ebike or Ecar? Are they any good?

I'm looking at an inexpensive repower for an electric boat that I just aquired. Looking at switching from the four lead acid 6V batteries and upping the power. As it is we're pushing a massive ~1.3 MPH top end at 25 amps and 24 volts. The motor is reported to me as a golf cart motor. It is a DC motor has zero markings on it anywhere! I pulled it apart to change the bearings and the brushes and commutator are in excellent shape, practically like brand new. The brushes weren't even broke in!

Anyway, I know that this is going to get boring for me if I leave it as it is. :cry: :lol: Looking at a max of 10 MPH as the lake we live on has limits of 5 MPH and electric power only.

the mnke 20 amp 5000mah 26650 that im testing is a very affordable cell, im actually considering it for an electric boat.

20 connected in parallel would be about 100ah and can run 6.8amps continuously or 136amps continuous for 20p

7s20p would be roughly 24v 100ah

theres this battery also
