Buying E-bike kit

Post by deljy » Thu, 12 Aug 2010, 04:43

Hey guys, I've decided to buy an e bike kit. I'll be trying to keep the price as low as possible but I require assistance choosing the batteries. At the moment I've found the hub motor which im going to get so now I'm left to choose the batteries.
Initially I was 100% set on 3 SLA batteries (12v 14A) but after finding the total price of 3 12v 14a batteries is over $250 im seeing whether their are any other type of batteries around a similar price (around $300?). I was told it was possible to create packs using cells (such as A123 cells) which can change the price depending on how many amps you want the pack. I'm quite illiterate when it comes to batteries so any help would be apreciated. Are SLA batteries the best and cheapest option in the end?

Cheers

I put together a GoldenMotor "Magic Pie" kit for a customer this week.

Specs:
Front hub (inbuilt controller runs 24,36 or 48V)
48V 12Ah rack mounted LiFePo4 battery.
Twist throttle.

At 48V it's rated at 750W. It pulls great up steep hills and has a top speed between 35 and 45 kmh (dependent on rider weight)

This kit was an absolute breeze to install, it literally took 30mins. The total cost delivered was AU$980.

I have nothing at all (other than being a customer) to do with Goldenmotor, but this will be my kit of choice from here on.

Gow.

PS: at 24V it think its rated at 250W (Aus legal)
If you are not part of the solution, you are part of the problem.

Don't waste your time with lead acid batts. A lithium pack is so much lighter and more powerful and will take many more cycles than lead acid. The price is coming down all the time.
