These are genuine LG INR18650HG2 rechargeable lithium-ion batteries with a 3000mAH capacity.
We spent nearly two months to find the best 18650 battery we could in regards to a good balance of performance and capacity. This is what we decided on. The INR 18650 HG2 from LG has a great capacity at 3000mAH and can handle continuous discharge rates up to 20A. You can find other 18650-type batteries with higher capacity on the market but most will either have a much smaller continuous discharge current rating, cost significantly more, or be fakes with a fraction of their labeled capacity. One reason we wanted to have a higher discharge current rating was for safety; for example, you can accidentally short this battery for a brief moment and the battery is not likely to vent or rupture, whereas some 18650-type cells will easily explode after even a brief short circuit situation.
These batteries do not have built-in protection circuits. We recommend using our TP4056 Charger and Protection Module to add the necessary protection for these batteries.
When you receive your batteries they will arrive partially charged by Addicore; this is to prolong battery health during storage. If you don't plan to use the batteries soon you can leave them as is, but prior to use it is recommended to fully charge your batteries.
IMPORTANT: You must do all that you can to prevent your batteries from ever being short-circuited or overloaded, which will cause permanent damage to your battery and, if prolonged, can cause the battery to get hot, or worse, to vent or even ignite. We have carefully chosen these batteries since they have a high continuous discharge rating. Since they have such a large discharge rating the batteries can withstand brief short-circuit events, but we absolutely advise against ever intentionally doing this since it will cause a permanent reduction in the battery's capacity. Also, be very careful to never install the batteries in a battery clip or device in such a way that could cause a short-circuit. Since these batteries are round in shape, caution must be exercised to avoid situations where a battery could roll into trouble, such as rolling off of a ledge or table and becoming damaged or punctured.
