Small Lipos are less than $20. But if you need 12Ah worth of 3s LiPos, you're looking at two of these at $49 each, so $98 or so, which is over double what the equivalent gel cell battery would cost.

I'm not saying that it's not worth the cost, but certainly they're only cheap if you need a small one.

Finally Bought the LED Lights I started this Thread about:


WE ARE Experiencing Technical Difficulties…

Please Stand By.

Red and Black Alligator Clips. Red is Positive+ , Black is Negative- .

New Tail Light by AviationMetalSmith, on Flickr
A Red Tail Light, 12 volt, milli-amp current drain. These are two and a half inch diameter, and came without mounting hardware. I had to cut a Coroplast™ Face Plate with an Xacto™ Knife, to hold the Tail Lights to the Rear Panniers.

A Blue Plastic Electrical Junction Box (a.k.a. a Gem Box, a.k.a. Old Work Box) To protect the connections.

Amber LED Marker Light on the Front Fork. This required the making of some Hardware. The Board is 6mm Coroplast™, which was painstakingly cut with an Xacto™ Knife. Then the Board was Creased , Twice, along Two Lines 1.2mm apart . Using a Hammer and a Chisel. Then the assembly was bolted to the Fork with a 1" U-Bolt.

The actual Headlight. The Coroplast™ Box (a.k.a. Handlebar Basket) has a Lid made from a Polyethylene Cutting Board.

Coroplast™ by AviationMetalSmith, on Flickr
Coroplast™ Discs were left-over from cutting out holes for the Tail Lights.

These are the Batteries that I use.

These are the Connectors that I have grown fond of using. I no longer solder, Nor do I use Crimp-On Connectors. These Twist Lock Connectors are far more reliable.Unfortunately, these are Not available in Europe.

The Twist-Lock Connectors for the Tail Lights. Again, I must apologize that these are Not available in Europe, and are probably considered "Contraband".

The Tail Lights lit up. The Photographer was forced to put an orange road cone over the Headlight, as a Diffuser, otherwise the Photo would have been "washed out".

In Conclusion, I hope Everyone has there Lights ready for the End of Daylight Savings Time Tonight. I hope this reminder saves at least one Life.

Additional Lights have been installed. Now, the bike has three headlights, of 280 Lumens each, for a Total of 840 Lumens, And the rear has LED Tape, to accent the Triangle.
