AvidAirsofter776 Posted September 21, 2017 Share Posted September 21, 2017 I bought a VP racing 8 cell 9.6v battery and web auto stop charger to replace the previously fried batteries due to a non auto stop charger. Turns out neither stop. Anyone else seen this and any tips for the future? Link to comment Share on other sites More sharing options...
Supporters Sitting Duck Posted September 21, 2017 Supporters Share Posted September 21, 2017 Nimah's are a pain the batteries start to fade, often not holding charge for very long at all or one cell goes tits up or they get very very warm/hot on charge and nothing goes in the battery eventually you will probably be best going lipo get a B6 if possible than a B3 charger buy lipo's from places like hobbykuying stop paying silly prices for over priced batteries/chargers that don't last there are numerous posts about make the jump to lipo's & not buying over priced batteries from airsoft shops etc....

Supporters Rogerborg Posted September 22, 2017 Supporters Share Posted September 22, 2017 What'st the voltage output from the charger? It'll need to be in excess of 9.6V for it to be able to fully charge that battery. [UPDATE] Oh, this one? http://www.patrolbase.co.uk/airsoft-battery-chargers/asg-intelligent-auto-stop-nicd-nimh-battery-charger.htm That does claim to charge 8 cell / 9.6V packs, but based on similar chargers it may do so at a rate as low as 150mA for a 9.6V pack. If you're charging a fully discharged (e.g.) 2000mAh 9.6V pack then you're looking at 13 hours to fully charge it. Link to comment Share on other sites More sharing options...

Completely befuddled by it. Link to comment Share on other sites More sharing options...

I have been thinking about making the change to lipo, however there is no such thing as an 8.4v or 9.6v lipo that I can find. I wouldn't like to go as low as a 7.4v because it'll be a slug to shoot and I'm worried 11.1v will ruin my motor, and I'd have to get a MOSFET, which all adds up to way too much to just have a functional gun. It's probably what I'll have to do though. And I might as well. Better start saving! Link to comment Share on other sites More sharing options...
Supporters Rogerborg Posted September 28, 2017 Supporters Share Posted September 28, 2017 Individual nimh cells are nominally 1.2V, so batteries can be had in 7.2V (6 cell), 8.4V (7 cell) or 9.6V (8 cell). Individual lipo cells are nominally 3.7V so batteries can only come in 7.4V (2 cell) or 11.1V (3 cell). Link to comment Share on other sites More sharing options...
Supporters Sitting Duck Posted September 28, 2017 Supporters Share Posted September 28, 2017 Lipo kit on a budget..... https://hobbyking.com/en_us/turnigy-nano-tech-1200mah-2s-25-50c-lipo-airsoft-pack.html https://hobbyking.com/en_us/turnigy-12v-2-3s-basic-balance-charger.html (Both are in stock & in UK - stuff can be located all over the place UK - EU - Hong Kong etc..) G&G crane stocks can be a bit slim - 18mm to 20mm max diameter with about 5 inch or 126mm length You could get some slightly larger size/capacity ones but they may/may not fit so easily.... They might also be out of stock UK & order from EU instead (no biggy but 2 x postage or order all EU) G&G crane stocks can be a tiny bit smaller but that lipo should fit ok no problem (you MUST measure your gun to be sure before ordering though) Charger - cheapo B3 type charger that charges through balance lead - a bit slow but idiot proof no fancy setting n crap - charges through the small connector or balance lead as its called needs a psu but if you got and old psu from say a modem/router it "might" fit or a fancy variable voltage laptop universal psu can be used if you got half a clue or splice the ends of the lead that comes with it and wire it up IF YOU KNOW WHAT YOU ARE DOING !!!!!!!! Budget setup that gets you going cheaply, 2 batteries + charger under £20 inc postage) (If you get into this stuff then rewire to deans & ditch small tamiya then get a B6 (genuine model if possible than a clone copy) charger blah blah blah) They come off charge @ 8.4v - 2 x 4.2v max volts freshly charged btw Link to comment Share on other sites More sharing options...
AvidAirsofter776 Posted November 11, 2017 Author Share Posted November 11, 2017 I've since changed to Lipo and am currently loving it, it just works so much better! Link to comment Share on other sites More sharing options...
