Is 48V 15AH LiFePO pack enough ...

[allroads]

for a Currie e1000 scooter motor ? or is it too much. Currently I have 36V 10ah SLA. Need more distance and time.

If the Currie e1000 is a brushed motor it should be ok @ 48v.
You will have to look @ the controller in the scoot.
It will have a label,hopefully describing upper/low limits, with all sorts of stats.
To see if it will be OK @ 48v.
Brushed controllers are relatively cheap. so you can buy a new one, if the original doesn't suffice.
With stock gearing the scoot will be about 25% faster & go 2x as far.
Depending on the LiFe source, over 36v of sealed dead acid.

Where are you sourcing 48v15ah LiFePo?

Wh math - 36x10 = 360Wh, 48x15 = 720Wh. That's the battery energy available and in reality, SLA performs only about half rating so you're looking at 3-4 times current capacity. Of course if you use the higher voltage for higher speed you'll drain the battery faster.

Another often overlooked parameter is how long your motor will last operating at higher speed and significantly longer run time?

Ping was on my list but are there others here in USA rather across the pond?

I really need more distance traveled, speed is gravy for me. where should I get it? Some say Ping but there must be others who do equally good work. I like to buy made in USA!

'sorry, not much help for sourcing LifePo as I primarily run RC Lipo. 15Ah Ping should be able to handle the Currie power but possibly not? Regardless of battery best to own a power meter. Get one of these - http://epbuddy.com/index.php?main_page= ... ucts_id=42

IMO you need battery with high C rate such as RC Lipo or A123 (Cellman) packs. http://www.emissions-free.com/id47.html or study up about RC Lipo and determine if that's something for you or not.

As a general guideline SLA delivers roughly 1/2 capacity rating when used for motive applications. Your 10Ah SLA on a good day might deliver 5Ah. LifePo or RC Lipo will get much closer to delivering rated capacity and with proper C rate do it with much less sag than SLA.

I applaud your patriotism but sadly the best you could find is ''ASSEMBLED IN THE USA'' with imported goods made in China. Same problem here in Canada. But at least your scooter will ride in the USA right.

If you're patient and have some tools and knowledge, you could wait and get 12 used Makita Lithium Ion battery packs and make a 10S9P battery for your scooter with the good Konion cells inside. You would get 37V 11.7Ah. Then you would need a Hyperion 1420i charger with at least a 12V power supply. You could get all this for around $400, maybe a little less and you would end up with a really nice set up.

P.S.: I'm no expert at this, I just wanted to share what I learned so far. I'm a noob that wants to give back a little.

If your willing to build your own battery pack, then maybe 20Ah cells from a123 could be an option, they are available relatively cheap at the moment ~1$ to 1.5$ per Ah..But pack assembly is not as trivial as with other cells..

Again I am a true novice or even a noob at best, all these numbers is so confusing. Trying to upgrade the scoot with a better disc brake, new pads,and new shock soon.
I am retired and I mainly use the scoot for traversing large flea markets, it covers a vast area in little time and hope to pass four or more times compared to maybe twice by foot. Currently with the sla, I can do it three times at best.
So a lithium will give me that objective.
What I don't understand is the difference between the two: lifepo4 to a123. Since the motor
I have is 1000 watt with a controller which can handle 48v which is best suited and above all safe and maintenance free?
Isn't the latter used for RC applications? But I'm also reading users have them in bikes too.
What gives and which decision is best.
By the way I am not ready to build a pack on my own, would like to purchase one complete.
