Thought I could share something I did for demonstrating of A123 lifepo4 cells that were supposed to be used in our hydrogen car Wanted something that could let me replace cells and have total control over the pack, and look good so we can get more budget for our next projects lol. The...

I liked the rear suspension design :D

Ever seen an arc welding in action? Once the arc jumps onto the grounded plate, you don't have much control left on it and in a few miliseconds, the surface will be blazed, and the electrode is introduced to this hot spot, instantly melting it onto the surface, creating atomic level bonds. Using...

Swift transfers are evil, banks can do a similiar thing paypal does (cutting fees from the amount sent if any cost arises even after paying the cost in front) unless you especially ask for the written amount of money to be transferred to the sellers account. Over here, paypal seem to have better...

Sure I'm tracking them with a voltmeter, trying to get a multimeter that can show multiple voltages on the same screen.

Right now, I'm using a sigma lifepo4 balanced charger to balance the cells and big coil of resistance wire to discharge batteries and see which one nears cut-off voltage first, one cell out of 6 cells I bought off that olympics ebay guy is way off balance, rest are doing quite well. My team lost...

Istanbul :) PM'ed you, would love to talk!

I'm not tempted to buy a BMS as these batteries will be used for one single race, and once they near cut-off voltage, they won't receive full charging until the end, maybe some regeneration. Also i'm located in Turkey, gotta be careful with the package customs. Right now, i'm planning to use a...

No idea how to build a BMS though.

Hello, I have a question, searched about it on the forum, http://endless-sphere.com/forums/viewtopic.php?f=14&t=8226&hilit=paralleling Basicly, I will have 24 a123 lifepo4 cells and need them in 8 series. I wanted to parallel them as 3 cell formations first before connecting them in series...

This charger looks excellent, are there any shops that have it in stock? Hobbycity shows -6
