G&G firehawk stopping firing/cutting out

[Compulsive Reload]

May just be video quality but when looking at the muzzle it seemed it was misfeeding quite a bit. 

I'll prob try and test it soon then, jg scorpion arrived so messing with that atm.

Those fireproof bags are for charging as well. Good idea.

Voltage tester  - your better off with a cheap multimeter. You can pick them up for about £10. And for that you get a whole load of useful functions. For the money it's better than anything designed specifically for airsoft.

Voltage testing with them is as easy as selecting the correct function and touching the probes to the battery terminals.

They also come in really handy for looking for electrical faults if you know how to use one. You can use them in the home and car as well. I have a couple because it's the first tool I grab  when I have any electrical problem.

Got the voltage tester,stick battery showing as 8.31 on 20v via tester 

Cranestock showing as 7.53

That okay or....

Both 7.4 25c batteries

yep that's fine for storage.

7.4 lipo's don't actually run at 7.4v.

Fully charged they have about 4.2v per cell, 7.4v batteries have 2 cells. So fully charged expect to see 8.4v.

Fully discharged they have 2.8 to 3volts per cell. So expect to see 6 volts.

Storage voltage is 3.8v per cell. So anywhere in the 7.4-7.8v range will be best to store them, It doesn't need to be a set voltage for storage, Close enough is fine, provided it's not fully charged or discharged.

Ah okay awesome, do they discharge slowly in storage/will you have to top them up?

When is the voltage too low to charge on these?

Thanks.

A good charger will tell you when there too low.

They have some interesting properties.

If you discharge them too low nothing will happen. It's when you charge them from that state they have problems. A good charger will have a feature that refuses to charge a battery that is too low.

They might loose some voltage in storage but it won't be a lot, You can check them every couple of months, but it'll probably not show a significant change.

2.8v per cell, 5.6v is the absolute minimum you want to go. But the gun will be running very slowly, perhaps not even cycling at all by that point.

Oh that's all good then, will probably be using them regularly anyway, only have a basic one currently.

Yeah if it slows down I'll just switch it out.

Thanks again
