What is the purpose and need for such high current discharge rates on batteries?
If the light only draws 3A at the tailcap, is there any benefit using a cell thats capable of ~10A discharge? Wouldn’t the $$ be better spent on higher storage capacity?
I have a Convoy L6 incoming, my understanding is the stock light draws ~5A on the highest mode. What do I gain using 26650 cells capable of higher discharge rate capability?
thanks!!
For drivers like in the stock L6 there is not as much of a performance advantage of using high discharge (low IR) cells because like you say, the current is limited by the driver. But after the cells are partially discharged the voltage supplied by the batteries might not be enough to send 5A to the LED. High discharge cells will generally maintain higher voltage throughout the discharge and so can maintain the 5A to the emitter for longer.
On the other hand, for direct drive drivers like FET drivers, the current that is sent to the LED depends on the total resistance in the circuit, so using low IR cells will increase performance.
OK got it thanks…
Are these BestKalint IMR 26650 cells a good choice for the L6?
thanks!!
I have not heard of that brand so I can’t say if they are good. Any decent cell will work as long as they physical fit in the tube and have enough of a button top to make contact in series. Check the L6 thread for cells people use.
Better try here,there is no battery with 90A discharge !
