Default Build your own two cell A123 receiver battery pack

More and more of my club members are going to either the LiFe or A123 battery packs for the receivers on their gas/glow engines. Or as backup receiver power for the larger electric models.

The attached PDF file shows how a battery pack was built up using two 2300 Mah A123 cells, and a few other parts.

Voltmanbatteries is a very good USA A123 cell supplier. Their cells have spot welded solder tabs that are easily soldered with a 40 watt soldering iron.

Bad news, Voltmanbatteries no longer sells A123 cells.
Good news, Voltmanbatteries now has them in their Ebay site. (02-27-15)

I just purchased some from this place, they worked well. They do not have solder tabs however. You absolutely must purchase a Weller 100 Watt temperature regulated soldering iron to solder to these units.

Again, buya123batteries.com has closed down their web page, for several weeks now.
