New tech lead acid

[docnjoj]

I spent 18 years in Vermont and cow tipping used to be all the rage. Really silly but they do tip over. Kinda funny in a sophmoric way! Kids there dont do it any more. (sorry about the thread hijack)

Actually back on topic, Im going to try the 36 volt Ping on the MY1018 today, if it stays below 90. Its too hot to ride this week. God love A/C and pools!

My thread for the ePower Challenge is located here: http://endless-sphere.com/forums/viewtopic.php?f=3&t=4426

The PIR is Portland International Raceway where they just held the first electric bike races! Theres a thread somewhere in this forum! Really interesting!

I'm sure a lot of people noticed the positive reference to lead acid battery use in the PIR racing stuff. Interesting, that. I'm going to try lead again since I just got two new ones (24 volts) on the cx24 Mongoose I just gutted for my trike power. I then can attempt to destroy the motor with my normal 35 cell NiMh pack, or my wifes 36 volt Ping. But if the Curry system proves suitible on 24 volts, so much the cheaper for me!

How is your Mongoose? I would love to hear about it. I've been searching high and low for someone with actually experience. How easy is it to switch out the battery on this guy?

Just to be sure, this is your bike correct? http://www.target.com/Mongoose-Electric-Motocross-Bike-CX24V200/dp/B000MS8322/sr=1-1/qid=1212721014/ref=sr_1_1/601-0541613-7540122?ie=UTF8&index=target&rh=k%3Aelectric%20bike&page=1

I'm trying to post under "3 speed hub on Ezip" in the Ebike Technical section. More today if my keyboard wash works! NO to the above Target bike. A cheep imitation. Try thesuperkids.com for the real thing! Just a little more $ for a lot more bike!

Firefly technology powers Oasis batteries

This summer a new lead acid battery will arrive. Initially, the advanced battery technology will be used in Oasis truck batteries to power long haul trucks. Plans are in the works to develop batteries for hybrid and electric cars.

Lead acid batteries have been around for decades, but suffer from several shortcomings. Traditional lead acid batteries are subject to a short life span from corrosion of the positive grid and sulfation of the negative grid. Symptoms of this corrosion can be seen in that white stuff that collects on your battery connectors and cables preventing the battery from properly powering your car.

Firefly has solved the corrosion problem by replacing the typical lead grid with a new Microcell composite graphite foam grid. The Microcell grid is then filled with a “slurry of lead oxides”. The new foam grid reacts the same way as the older grid did except that it lowers the weight of the battery while improving the life span.

The Firefly technology, developed as a research and development project at Caterpillar, has also increased the efficiency of the battery and reduces the recharge rate. The technology also increased the number of deep discharges the Oasis can handle to four times what a normal battery can handle

Environmentally, the Oasis with Firefly technology, is much cleaner than nickel or lithium based batteries. Why? Because 97% of lead acid batteries are recycled for free. There is no comparable program for nickel or lithium batteries. Most recycling programs for the two newer technologies require you to pay them.

Because the life span of the Oasis is so much longer than other batteries, fewer of these batteries will need to be recycled. The graphite foam grid can simply be burned away, releasing the lead oxides to be used again.

This battery is expected to be available this summer. Since the process to create it is cheap and uses regular battery manufacturing processes, the cost should be similar to regular lead batteries but with the huge advantages outlined above.

Hopefully, this technology will be available for cars soon. The reduced weight, increased longevity and improved efficiency would be wonderful for hybrid and electric cars.

Safe, good of you to once again finally get up to speed, what with having to shift gears all the time.
