Danny-T418 Posted March 26, 2016 Posted March 26, 2016 Hi guys I'm thinking about changing my battery's for lipo's I have a G&G t418 I have read mixed reviews some say if you let them run down to much they blow up and if you discharge them to much the can blow up some say they damage the gun do you need to discharge lipo because I'm thinking about buying a nuprol 3000mAh 7.4v 20c nunchuck lipo battery and the charger is a balance charger with display but it's say it will only charge 2-cell 7.4 but the battery does not say how many cell it has and the charger isn't a discharger can any one help I'm confused

Baz JJ Posted March 26, 2016 Posted March 26, 2016 I used to leave mine fully charged between games and they puffed badly. I dont do that anymore.
Supporters Sitting Duck Posted March 26, 2016 Supporters Posted March 26, 2016 Really - I've got one 11.1v that is a bit puffy but not noticed it on my usual 7.4v's one of them got run really low that gun failed to cycle but still works which I was quite amazed at - thought yeah that lipo is shagged I mean they come charged up - to what actual volts I don't know probably 3.7v-ish per cell What I will say is that a cheap B3 type balance charger was deffo over charging a bit - maybe 4.25v+ per cell and that may not have helped Also if anybody gets a LiFe battery - well don't coz think they ain't that great DO NOT USE A LIPO OR LIPO SETTING as these are 3.3v cells if you charge a LiFe up to 4.2v it will damage the LiFe battery some chargers have a LiFe function or setting - so use the LiFe setting for LiFe batteries - not LiPo settings
Baz JJ Posted March 26, 2016 Posted March 26, 2016 No the problem was that I fully charged them after a game (7.4V) and then didn't use them for sonetimes months (the next milsim). I replaced them and now discharge them down to about 50% for storage and they are fine.

I replaced them and now discharge them down to about 50% for storage and they are fine. What's the best way to discharge them, just shoot the gun?
Baz JJ Posted March 26, 2016 Posted March 26, 2016 I bought one of these and just leave the battery plugged in until I get it down to the right level of discharge. RC Cell Meter-7 Digital Battery Capacity Checker for NiCd/NiMH/LiPo MJ About £5 Berto 1
Supporters Sitting Duck Posted March 26, 2016 Supporters Posted March 26, 2016 there is setting on B6 in the manual somewhere... I have enough fun if I try to alter Lipo to Life and back to Lipo again jeez I tried saving some settings but thought a prog fet was tricky but B6 gets a bit wtf if you start altering some of them mofo settings that is all I know yeah got one them thingy's too but for checking amps really or balancing qwirky lipo's had one on B6 that was all over the place.... balanced on this thingy majig recharged and lipo balanced a little better - bit w@nked still but balanced w@nked than before http://www.ebay.co.uk/itm/RC-Helicopter-Watt-Meter-DC-60V-100A-Balance-Voltage-Battery-Power-Analyzer-UK-/291305470857?hash=item43d328bb89:g:ticAAOSwkNZUcql0 sure they were only about £7 or £8 last year - jeez inflation... or are you talking about this: http://www.ebay.co.uk/itm/Key-Ring-Style-Lipo-Battery-Voltage-Checker-HobbyKing-2-6S-RC-Lipoly-Cell-UK-/191703062448?hash=item2ca26497b0:g:BZAAAOSw~1FUXOm8
Baz JJ Posted March 26, 2016 Posted March 26, 2016 I keep it real simple. A LIPO charger that balances and the lights all go green when they're charged and one of these meters to monitor charge in percentage terms and to slowly discharge my batteries when needed. Sitting Duck 1
Supporters Sitting Duck Posted March 26, 2016 Supporters Posted March 26, 2016 gotcha - might one of them anyway from Hong Kong seems to be like the other one but balance board built into meter already

Yes a poorly treated LiPo can catch fire, so don't pierce it or hit it with a hammer etc. Don't run them flat as they won't recover easily so will destroy the batteries life. a 7.4v LiPo is a 2 cell LiPo, 11.1v is 3 cell. Day before a game, plug in battery to balance charger, turn it on, wait a bit.... wolla... battery is charged. They hold their charge well over time, they do not need any more fuss than that really, just keep an eye out for them swelling or damage to the protective covering and don't short them out.
Supporters Sitting Duck Posted March 26, 2016 Supporters Posted March 26, 2016 don't worry about the scaremongers... They only catch fire if the UK comes out of EU No lipo's are a lot safer if we come out of EU then we have more control over our lipo's borders economy and funny shaped carrots/banana's etc... The scaremongering is stop idiots like me thinking stupid thoughts and being a dick with lipo's trust me they are fine - just don't do stupid $hit... (says king stupid $hit himself)

Danny-T418 Posted March 26, 2016 Author Posted March 26, 2016 This may be a silly question but me being a noob I've just been looking a a 7.4 lipo battery and there are two adapters is one of these a deans adapter
Supporters Sitting Duck Posted March 26, 2016 Supporters Posted March 26, 2016 look at ya gun - it is likely small tamiya.... two top right connectors are male/female small tamiya - reckon 90 to 98% stock guns will be small tamiya (probably 99% but I don't own every gun out there) bottom right 4 are large tamiya - unlikely to be used in most guns - maybe big fixed stocks but should have adapter from Large to Small Tamiya bottom left is a small tamiya btw like top right two 3 on top left are deans - usually found on upgraded guns - allows more current to flow through thicker 16awg wires to motor (16awg is quite thick and not all guns/gearboxes can squeeze in wires as thick as that) other connectors found/used... mini deans - unlikely to found but have seen a US baby M4 AEG that came with mini deans XT60 & banana plugs - mainly used on RC stuff than airsoft but some do use these connectors on guns I have seen Airsoft is usually small tamiya or Deans if upgraded as in picture sometimes using RC batteries that have XT60 connectors you need to re-do connections or get correct adapter polarity differs also on Large & Small Tamiya's so if using an adapter double check polarity is 101% correct Lipo's often have a min of 16awg - often 14awg, or higher burst 12awg+ wires in them jeez - really thought most of all this would be in that 3 page essay posting we done a while back I think I'm done on this for now - if you speak to componentshop.co.uk they will sort you out and answer any queries Sacarathe 1

Guest PT247 Posted March 26, 2016 Posted March 26, 2016 depending on the type of charger you buy you will either have to connect both to the charger when charging or just the balance connector.

Sacarathe Posted March 27, 2016 Posted March 27, 2016 Maybe if you don't answer duck, people will find the search, perhaps someone should do a thread of threads on airsoft batteries... All that said, your help was much appreciated in the questions sticky. Good stuff, i usually charge my lipo after a game, guess i got to stop. :) Sitting Duck 1
