Astrolux FT02S New Color 11000 Lumens How To Choose The Right Battery

[mortuus]

yes true if u can find Molicel P42A its the best 21700 cell in terms of amps it can discharge.

[Nitewalker]

Is it safe to use 5000mah unprotected battery with max discharge of 15A with this flashlight, since it can pull up to 30 amps ?

[mortuus]

Yes its safe, u will just not unlock full potential of the lights lumens with that kind of battery.

But if u dont want use turbo only top of ramp then its a good choice using such battery and u get longer runtimes.

Thanks for your answer mortuus

@Sirstinky

…The 26650’s will give more runtime but lower output…

Will that brightness difference be noticeable, and for how long?

The difference in brightness is not so much

I’ve liked these so far in higher drain lights. Hohm Tech Grown² 26650 4244mAh 30.3A Battery - 18650 Battery Store

Size: 26650
Style: Flat Top
Nominal Capacity: 4307mAh
Continuous Discharge Rating: 32.3A
Can be charged at a tested/proven 5.30A - I still wish the chargers would hurry up and increase the charge rate to newer standards. 5amp multi-bay chargers should be available today imho. The R/C hobby industry has been running lipo at high C charge rates for years.

Looks like the 26650 Shockli have a higher Mah rating @5000. Testing to about 4900mah.

Don’t high charge rates diminish battery life?

[Sirstinky]

Over time, yes. Generally you want to set your max charge rate to half the battery capacity, so a 5 Ah battery would realistically be 2.5 Ah. This isn’t a rule of course since different chemistry require different charge algorithms (li-ion vs nimh, bs lifepo4) and rates.

OK, thanks.
