Help with parts needed

[iainm]

I want to use the Rebel Green LED in my saber. I also want to use rechargeable batteries and a charging port. Please advise me what parts to purchase - which battery pack, buck puck or resistor and size etc. I want to use a regular unlit on-off switch. No sound required. Many thanks.

Any 3.7v li-ion battery pack, a recharge port, any latching switch, the Rebel Green LED, and you can calculate the resistor with the resistor calculator in my signature, or read this post http://forums.thecustomsabershop.com...e-to-Ohm-s-Law to learn how to calculate them yourself.

So, how about this. Will this work? Too much, too little power? Rebel Green. MWS Recharge Port, MWS Long Latching Switch, Li-Ion 18650 3.7V 2600mAh PCB Protected Rechargeable Battery Module and a BuckPuck 1000mA 6-wire. The resistor chart suggested 1Ohm 2Watts or 1000mA BuckPuck.

If you go with the BuckPuck, you will need to move up to a 7.4v battery pack. The BuckPuck requires a minimum of 5v to operate properly.

The resistor is easy to hook up, very inexpensive, and will operate fine with the rest of your setup.

Nice. Thank you. Filling the shopping basket now...

Had to wait until the 15th to be solvent again! Just noticed that USPS Priority International does not allow Li Ion batteries to be shipped. Can you recommend an alternative for my saber that is not Li-Ion. I still want to be able to recharge the battery without dismantling the saber.

Finally found a company in Turkey's business capital Istanbul that MAKES Li-Ion batteries. Here is what they can provide. Which one would best suit my requirements?

2200 2900 and 3400 mAh and 3.7 Volts The sooner someone can reply the sooner I can place my order with these people.

Thanks and Merry Christmas.

It depends. Typically I say to go with the highest mAh you can fit in the saber. Physical size is the more important factor here.

If you went with the BuckPuck, you'll want a 7.4v protected pack. As a reminder, two 18650 sized li-ion batteries will not fit side-by-side in MHS parts, though they will fit as a stick pack.

If you're using a resistor, go with the highest mAh single cell li-ion you can find. It should be a 18650 sized cell, and a single one is typically easy to fit into a saber.

Thanks for this. Very helpful. One more important question: what kind of recharging device should I use? Another question: does the mAh value dictate the size of the resistor? If so, what size resistor would I need for a 2900 and 3400 mAh battery? Thanks again.

No, the mAh is how long it will last. Picture a bucket of golf balls, the Voltage is how high the bucket is and the amperage is how fast they are falling out of the bucket. The resistor is to keep the golf balls from cracking no your skull when they hit. The mAh is how big the bucket is.
