LiPo Battery 1500mAh 3.7V 903450, Polymer Lithium Ion

!!!!! IMPORTANT !!!!! These are very powerful batteries, and extreme care should be taken using them. Only use with brand name, quality chargers(like Nitecore) and equipment! Unfortunately we can not replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we can not possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these(or any other Lithium Ion) batteries with proper Lithium Ion chargers and equipment. Lithium Ion batteries can easily be damaged by charging them with too high current, or exceeding the maximum rated current discharge. In worst case Lithium Ion batteries can explode or catch fire when used improperly! Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!

• Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
• Do not over-discharge! Ensure the equipment you use this battery in will not draw more current from that batteries than it stated "Maximum Continuous Discharge Current"
• Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
• Do not short circuit your batteries! NEVER short circuit a 18650(or more other) batteries! Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your mod, or even your face!
• Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a good way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.
• Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries they’ll release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling center.

The JST-PH 2mm connectors are often just referred to as “2.0mm JST Connectors”. This is a generalization of a specific product from JST, a Japanese company which make high-quality connectors. This connector is their PH series polarized connector. It has the advantage of being compact, durable, and difficult to connect backwards. Another feature, which can be an advantage or a disadvantage, depending on how you look at it, is that the JST connector is very hard to disconnect (although a carefully applied diagonal cutter can be helpful!) once it’s mated. While this makes it unlikely to fail during use, it also means that disconnecting the battery for charging can damage the battery connector.

This connector is widely used for single cell lithium-polymer ion batteries. For example, most single cell lithium-polymer ion batteries from Sparkfun use this type of JST connector, and many of their boards include it as a power supply input. 

This connector is compatible with the power connectors on the Logomatic v2 serial SD datalogger and uLog 3-channel datalogger, with the red wire connecting to + and the black to −.
