I got one of these recently – not rating that usb thing, would it be ok to just snip it off do ye reckon?
Yes, but…
1) Don’t do it while there are any batteries in the box, and:
2) Make sure the cut ends can’t short against each other. (Cut each core to a different length & heatshrink them??)
3) Somehow make it waterproof. (Self amalgamating tape??)
Or you *could* remove the very long lead with the superfluous USB connector and solder in a short lead with just the light connector (like I did):
It’s a bit fiddly as you need to unsolder the 4 springs in the lid of the box to be able to remove the pcb.
There is a protection circuit in the box, but it doesn’t have any connection to the junction between the cells in series (it is wired as 2S2P), so in reality, it can’t offer much protection (you can/will over-charge or over-discharge any of the cells if/when they become unbalanced).
I’m charging mine in the box for now, but it would be much better to get a charger that takes the individual cells.
It’s quite a bit more bulky than the standard issue Chinese battery, but it means I get 2.5 hours out of a Solarstorm X2 on high compared to ~1 hour on high for the standard pack.
