What draws current is the solenoid and whatever board is timing it, and that demand arrives as short hard spikes rather than a steady pull. Capacity therefore matters far less than the pack's ability to dump current on demand.\u003c\/p\u003e\n\u003cp\u003eThat is what the C figures describe. This pack is rated 35C continuous, which works out at 10.5A, and 70C in burst, which is 21A. A solenoid firing is a burst, so the second number is the one doing the work — and it is why a physically tiny pack can still give a clean, immediate break.\u003c\/p\u003e\n\u003cp\u003eEighteen grams and a 2S1P stack means it goes in the places an HPA build leaves you: a grip, a stock tube, the gap behind a receiver. It arrives with a two-pin JST (BEC) plug fitted and a three-pin JST-XH balance lead, so any balance charger will take it.\u003c\/p\u003e\n\u003cp\u003eGiant Power is an RC model battery brand rather than an airsoft one, which is rather the point — small high-discharge packs are a solved problem in model flight, and the electrical job an HPA board asks for is the same job.\u003c\/p\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eSpecifications\u003c\/h2\u003e\n\u003ctable style=\"width:100%;border-collapse:collapse;font-size:13px;margin:0 0 18px;\"\u003e\n\u003ctr style=\"background:#1B3A6B;color:#fff;\"\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"padding:7px 12px;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eChemistry\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eLithium polymer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eConfiguration\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e2S1P, 7.4V nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eCapacity\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e300mAh\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eContinuous discharge\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e35C — 10.5A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBurst discharge\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e70C — 21A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMax charge current\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e1.5A, fast charge (5C) capable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMax charged voltage\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e8.5V — 4.25V per cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMin discharged voltage\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e6.0V — 3.0V per cell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eMain connector\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e2-pin JST (BEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBalance connector\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e3-pin JST-XH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background:#f5f5f5;\"\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003e18g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding:7px 12px;border:1px solid #eee;\"\u003eGiant Power\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2 style=\"font-size:16px;color:#1B3A6B;margin:18px 0 8px;\"\u003eFrequently asked questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eWill it run my AEG?\u003c\/strong\u003e No, and do not try. Three hundred milliamp-hours is nowhere near a motor's appetite.

Check the voltage window your engine or FCU specifies before ordering — some accept 7.4V only, some allow more, and going over what the maker states can cook the unit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow big is it physically?\u003c\/strong\u003e Eighteen grams is the only figure the supplier publishes, and we are not going to guess the millimetres. If it has to fit a specific cavity, ask us and we will measure one before it ships.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat charger do I need?\u003c\/strong\u003e Anything that balance-charges a 2S LiPo. The balance lead is the common three-pin JST-XH, and at this size a low charge rate is kinder than the 1.5A maximum.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs 70C burst a real number or marketing?\u003c\/strong\u003e Treat continuous as the figure to design around and burst as headroom.
