EXCELLENT REVIEW!
Quote from Airsoft Soldier professional review:
"The results
Looking at the difference between RC and airsoft manufacturers’ batteries, the results were favourable to the airsoft batteries in the S3 class. Especially the Socom Gear S3 1500 mAh 15C solid pack exceeded all expectations and achieved the best result in the power test."

"The tests showed that the traditionally shaped Socom Gear batteries proved to be very effective and powerful batteries."

"C-ratings could only be measured for S3 batteries because of equipment restrictions. Socom Gear’s products gave as much as the pack promised, but the RC batteries were a bit short of their objective."

Warning:
Failure to follow these instructions can quickly result in leak, explosion, or permanent damage to the batteries and its surrounding and may even start a fire.
(1) A new battery comes in a discharged condition and must be charged before use (refer to the device manual for charging instructions).
(2) The battery should be used in the environment as listed below. Otherwise, the battery lifespan and function would be substantially reduced. Under extreme environments, batteries may overheat, explode, or even catch fire
(3) Similar to NiCd and NiMH batteries, lithium-polymer batteries can release extremely high voltages.
(4) Always use battery manufacture approved chargers to recharge the batteries.
(5) Always empty the chamber of your AEG, remove the magazine, put on barrel cap and put on safety before you change the battery.
(6) Never place the battery near the heater, fire, or any heat sources. Never throw the battery into the water or keep the batteries in a damp environment.
(7) Never allow a battery’s positive and negative leads to accidentally touch each other.
( Never connect the battery to the wall plug or cigarette lighter plug in vehicles.
(9) Never dispose batteries with fire or warm up the battery using any heat sources.
(10) To avoid short-circuit, all batteries should be stored or shipped free of any conductive materials, including necklace, hairpin or any metals.
(11) Never hit or throw the battery against any walls, floors or hard subjects which may damage the batteries by violent mechanical vibration.
(12) Never use hammer, nail or any sharp object to pierce or penetrate through the battery insulator.
(13) Never solder the battery’s connectors with wires.
(14) Never disassemble the batteries in any means.
(15) Never charge the battery in an extreme hot environment.
(16) Never place the battery in a microwave or pressurized container.
(17) Never use the lithium-polymer batteries with the disposable batteries or rechargeable batteries in different types, capacity or brands.
(18) Before and after every use of your lithium-polymer batteries, inspect all cells in the pack as much as possible to ensure no physical damages, discolor, heat emission, or swelling in evident. Such signs can often indicate that a dangerous problem exists and the batteries should be disconnected and disposed immediately.
(19) Always store the lithium-polymer batteries in a secure location away from children. If a child accidentally ingests the battery, the child should receive medical attention immediately.
(20) Remove or dispose the batteries immediately when batteries are leaking watery substance and emit strange order.
(21) Do not allow the battery’s electrolyte to get in the eyes or skin. Wash affected areas with soap and water immediately if they come in contact with the electrolyte. If electrolyte makes contact with the eyes, flush with large amounts of water for 15 minutes and seek medical attention immediately.
(22) To prolong battery life-span and to ensure battery full function, charged battery should rest for at least one hour before discharging.
(23) Never keep the batteries in an extreme environment, such as direct under sun light or inside the car during hot summer. Otherwise, batteries will overheat or even ignited to substantially shorten the lifespan and damage the function of the batteries.
Working environment: Charge：0℃~45℃/ Discharge: -20℃~60℃ / Storage for 30 days：-20℃~45℃ / Storage for 90 days：-20℃~35℃



More knowledge of Li-Po Batteries:
(1) What are factors to enhance the shooting speed (BPS, B.B. per Second)? Voltage, Currents and C. All three!
(2) What is your battery’s continuous current? mAh x C=mA, For example, Our 1500mAh, 10C battery, the continuous current will be 1500mAh x 10C =15000mA=15A (pre cell) A 11.1 Volt Li-Po batteries have 3 cells, so, the continuous currents will be 15Ax3 (cells)=45A
(3) What’s the current (A) my AEG needs? An extreme example: 120 meter/sec (393ft/sec) + 40 BPS (B.B. per Second) need about 60A. Normal AEG without modification (300 ft/sec) + 10 BPS only need start current at 20A.
(4) What is my battery life? Depends on the current your AEG needs. The lower current of your AEG, the longer battery life.
(5) How come people say the Li-Po batteries are dangerous? Normally, if you use the right charger, don’t pinch or penetrate your battery, the battery is very safe. However, no one can guarantee the 100% safety of the Li-Po battery, If you find your the battery expending, leaking, or become extremely hot, please disconnect the battery immediately. Please read our “WARNING” section for more details. If you need the 100% safe Li-ion battery, please contact MadBull Airsoft. Their LFP batteries are the only 100% safe batteries in the industry.
(6) How to tell other brands Li-Po batteries is stating the correct “C” value information? For example, there is a battery company states that their battery is 11.1V, 2100mAh, 20C, 42A. Is this the correct information? First, let’s check the C value is correct or not. Let’s do the calculation: 42A for 3 cells means each cell comes with 14A. As you know that mAh x C = mA, 2100mAh X C = 14A =14000mA., So, the C=6. You have to doubt their C value.
(7) Should I choose the T style (T-plug) connector (red color) or should I use the original JST connector (white color)? The standard JST connector can take 80A. Unless your AEG take a lot of current (A,) you don’t have to change to T style connector. However, a lot of AEG company’s JST connector didn’t meet the standard (using low quality materials), in this case, you’d better change your connector.
( What is shortage happened? From example, your connector melt or your fuses touch to other metals. If the positive and negative wires contact each other, your wiring cable will become extremely hot and will burn down the connector on the battery. Once the wiring get off the connector, it stops melting and burning. Unless you have expert to help you rebuild your battery, we will suggest you to recycle your battery.
(9) Let’s see what happened if I penetrate my battery or if I use the wrong charger to charge my battery: We have video uploaded to our website at SOCOMGEAR.com If you penetrate our SOCOM Li-Po battery, the battery will generate a lot of black smoke and the battery will become hot. When we did the testing, we use a thick cardboard under the battery and didn’t cause fire. However, this didn’t guarantee that you won’t get fire under the similar conditions. Our battery’s formula will reduce flame and heat but didn’t guarantee that it won’t catch fire. So, never try to penetrate your battery. If you use the wrong charger, per our testing video, the battery will only expand and stop working. However, don’t use the wrong charger. We can’t guarantee that it won’t catch fire or explosion under the similar condition.
(10) Why we are so confident that we know our batteries? We are coming from MadBull Airsoft’s R&D team. We have a lot of Phds and Maters as our backups. We don’t “re-brand” our batteries from other un-known factories. We make our battery in-house with high standard QC.

I like LiPo's, especially how small they are, but other than the size I don't need the 1200 rpm.

I like LiPo's as well. Size is awesome. The extra power is great. However, one thing to remember which I think is the most important; is that LiPo's, add a lot of extra stress and wear on your weapon. So you need to be comfortable with replacing parts more often.
