What is the Best 18650 Battery to use? 3 months 2 weeks ago #46784

ace1680 Offline Senior Member Posts: 55 Thank you received: 15	I am new to these 18650 batteries. I've seen them 900mah to 3400mah; from protected to unprotected, 14.99 to 34.99. My question is: What is the best battery for our sabers that will be using 12+ LEDs with sound, and is a higher capacity better?

It's really not such an issue with mAh as it is an issue with output current - even with a high capacity, cheap batteries won't be able to put out the 4A for single-blades and 8A for crossguards that the Saber Forge LEDs need.

The Saber Forge store carries 8-10A 18650s with a 3400mAh capacity. Those should work fine.

If you're wanting to buy in bulk, I found this recommendation from the Igniter manual:

Another good choice is the KeepPower with the 3 module protection circuit, as that battery can withstand high drain. These are usually on Ebay; just search for “KeepPower 18650 3400mAh” and pick ones that have the good protection circuit.

If you're willing to re-wire your saber, a 26650 might *juuuust* be able to squeeze into the hilt for an even longer run time.

ace1680 Offline Senior Member Posts: 55 Thank you received: 15	Thanks for the info. I currently have 2 18650. one 2500mah and one 3400mah. When fully charged they put out 4v and after about an hours use 3.7v at 8A, Would these ones work? http://www.amazon.com/gp/product/B0154NRFVE?psc=1&redirect=true&ref_=ox_sc_act_title_4&smid=A4DI0C83URB3Z

Dangerous for the battery. Saber could continue draining the battery past the typical 2.5v cutoff, damaging the battery.

Also, a bad charger might charge the battery up past 4.2v, which could burn out the saber LEDs.

I mean, if you were being really careful to always charge the battery when the saber got a little dim and used a proper charger with a 4.2v cutoff, it *could* work, but I'd never, ever, recommend it.
