So I just got my Amped eBike kit, but my problem is I have no batteries!

I want to go with Amped's 36V 10 AH Phylion Battery pack but I have no cash right now and he is back ordered.

A guy on craigslist has two SLAs for $30 ( SLA Batteries 12v 8aph ), for $30.
Not sure if these would work, but never the less I want to run with some SLAs for the time being until I get my money to get the better battery.

If I were to get the SLA batteries alone, where could I get a rig to hold them together?

thanks

Which kit did you get? Front or Rear?

Hi Truthstar,

2 SLAs will only get you 24V which won't be enough to power your motor. I would also not buy used SLAs unless you can load test them and be sure that they are functioning perfectly, it's also difficult to match a 3rd SLA to two older ones. It's best to buy 3 matching SLAs at the same time to be certain that they will work well together.

As for a big rig, I'm assuming a way to mount them to your bike. The conventional way is to get a heavy duty rear rack and strap them to the rack. I have mine sitting on top of the rack. Some folks put the SLAs into a box or bag to make them less noticeable. Be certain that the rack is sturdy enough to handle the weight!

I would say not to waste your time on the SLA's if you were originally going to go with their Phylions (exact same case as me!). I went to Ping, got the 36v15ah (figuring a little extra distance is probably a good thing) and have not been disappointed at all. No buyers remorse whatsoever, and I'm definitely on a tight budget!
If you can't manage it at all, then get 3 SLA's totalling 36v, then put them in a milk crate or other box hooked to your permanently mounted rear bike rack (you'll want one regardless). See here for instructions on how to make your own hardside panniers if you've got more motivation: http://bikehacks.com/homemade-hardside-panniers/
Good luck!

if you are in Canada, then check out the Yardworks Lithium Ion packs for the cordless chainsaw, they are 20Volts each at $109.

Two will get you up to 40Volts for $218. In series you'll get 6 Amp hours.
