Greetings folks, R U still reading this forum? I've had to give the eBike project a break for a month but now I'm back on it. If U R reading, could you please advise me on whether converting to a LiFePO4 might be great or terrible idea. There is an eBay seller in China who will build me a 36V 10Ah pack that will fit inside the original Ni-mh battery's case (and I presume would be much lighter an more efficient). Would you recommend this route, or should I continue to look for a reputable Ni-mh set. I had to get a refund for the last Ni-mh set mentioned in this thread. It was advertised at 10Ah but ended up running more like 1Ah or less. It seems like the cost of the LiFePO4 won't be much more than the pricier Ni-mhs, and I won't have to build it either as the seller will do so; and it comes w/ charger too. Any suggestions?
