So after a lot of thinking and exploring the replacement of my aging 24V 12AH SLA battery pack on my Giant LaFree, I ordered a PingPing 24V 20Ah LiFe pack the other day. Ping was quite helpful and responded to all my e-mails. I told him what I wanted and he came up with a solution. The LaFree has a 400 watt motor that peaks out at a 1,000 watts. I wanted to go with the 24V 10 or 15Ah pack to save money, but he said I really needed the 20Ah pack to handle the load. He is building the pack special so it will fit into my battery case on the bike. The pack is paid for, he says it will take five days to build and test the pack, add another week for shipping and I should get it by the middle of April.
I'm looking forward to have a screaming bike. The battery pack should perform extremely well compared to the original. I can imagine that with the added Ah's I should always have plenty of voltage on my short rides (less then 10 miles round trip) and have enough wattage to make to the beach and back (just over 20 miles round trip). I'm also expecting that the voltage will be consistently higher then what the SLA's put out.
I will give you guys a update as soon as I receive new information.
