Hi All
Thanks for the replies; it is a two-tone for a start... so thats all good. Half of it is blue.
On the charger front, I've attached some pictures; you'll see the connectors - and also the larger 700mah battery that came with the gun, then the 'replacement' I got sent that still doesn't make the gun work.... which leads me to thinking is the charger. I bought a multimeter and the batteries show voltage... the charger doesn't when plugged in - but not sure if thats only because it outputs stuff when something is pulling on in it.
I could solder a tamiya connector on both ends, locate a tamiya-style charger and do all of that... just 'should I'... is the question...
I will most likely get my son a replacement - theres a couple from Patrolbase I was looking at either the CM033 Thomson AEG or the DoubleBell Kar98 spring rifle...
Any other recommendations? Just annoying that you buy something... it stops working after 6 weeks with very little use and the retailer after a lot of pushing sent a battery that wasn't the same and then after that has basically given up. Very frustrating. Won't be using them ever again.
With those photos if anyone has a charger they don't use anymore and are willing to part with it... let me know
