Need suggestions on the following items.
A STURDY bike lock.
A Helmet.
A Seatpost cargo rack for stuff.
E-Breaks, worth it or not?
Oh yeah, and if you guys know anywhere I can get any of these components even a bit cheaper. Saving a couple bucks wouldn't hurt.

$1344.80, without all the shipping and stuff. It'll probably bring me right up to 1.5k like I planned.
 
Looks like a solid build to me. I don't see a throttle on the list but I'm nitpicking since that is all I can do about that list. Helmet choice is very personal. pick by what fits good is my motto, and where i live it must be white.
 
Hehe, yeah, a full twist throttle is on my list as well (Those things are waterproof, right?). I just found out a local outdoors store a few miles away stocks the 07 model of the Iron Horse Maverick, or they can order it from a warehouse. So that is $50.00 chopped off my budget. Other than that I am just waiting for Crystalyte to get back to me on where to get an empty battery box.

I just need opinions on cheap sturdy seatpost cargo racks. That is a must for carrying my stuff.
 
That appears to be a lipoly (LiCo) pack, not LiFe. Big difference.

:shock:
 
Looks like that will be a nice setup.

Of course you'll need a charger. The Powerizer website shows a Smart Charger: 37 V (1.3A) for Li-Ion Battery Pack for $33.
Powerizer website said:
The estimated charging time is about 11.5 hours.
Warning: Please wait 30 minutes after charged to allow PCM to balance the cells to achieve the best performance

Do those numbers seem normal? 12 hours between rides is doable but it may be hard to get in a full charge at work unless you work long hours.
Note: My 48V NiMH pack takes about 5-7 hours depending on the discharge level.
 
I'm not sure, it seems like Lithium batteries take a while to charge. I'm actually not completely dead set on using Lithium for my first pack. I am kind of leaning towards going with a cheaper NiMH pack like this.

What are the pros and cons to using NiMH verses using Lithium? Seems like LiFePO4 packs are sold out all over the place. I mean, I have found a few websites, but there is shoddy information on the cells and/or they are located far away from where I live (Out of the US).
 
most of the NIMH packs can't put out the continuous amps like the various Lithium types can, and some are pretty heavy as well. Be sure to double check the output of the cells. A neighbor got a new e-bike with a factory installed NIMH pack, and it is a wimp. It often cuts out when climbing hills-when you need it the most.
 
Guess I'll stick with Lithium. I found this. It uses LiFePO4, I wonder if it's any good?

Looks OK, but you could do about the same with DeWalt 36V packs... and have some kickass tools too.

:mrgreen:
 
The Dewalt tools are too clunky. After converting that tin tube to imperial measurements that too is too clunky. If I got my hands on a bunch of F Cell LiFePO4 is there anyone here that would wire them into the case I plan to order and slap on a BMS?

The DIY-BMS is not out of the oven yet, sorry... But soon!

I have heard no bad reports on them. and they can be paralell connected if you end up needing 20 ah to keep your controller happy. In general, the prismatic cell lifepo4 batteries don't put out that many amps till they get to the 20 ah sise. Try emailing Ping. I hear he is able to ship again. You want 20 ah just for the discharge rate. And whats not to love about huge range?
