This lithium ion pack is made of 3 balanced 2200mAh cells for a total of 6600mA capacity! The cells are connected in parallel and spot-welded to a protection circuit that provides over-voltage, under-voltage and over-current protection.\u003c\/p\u003e\n\u003cp\u003eEach cell can provide \u003cstrong\u003e0.5C\u003c\/strong\u003e of current (1.1 A per) so all together the peak current you can draw is over 3.3 Amps. Note that these batteries are not designed to sustain such high loads, we suggest keeping any constant current draw under 0.2C or 1.3A.\u003c\/p\u003e\n\u003cp\u003eThe packs come with color coded wires, and now they come with a JST 2-pin cable attached for use with our chargers! Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly. The cables are rated for 2A so if you use them keep that in mind.\u003c\/p\u003e\n\u003cp\u003eThe included protection circuitry keeps the battery voltage from going too high (over-charging) or low (over-use) which means that the battery will cut-out when completely dead at about 3.0V. However, even with this protection \u003cstrong\u003eit is very important that you only use a LiIon\/LiPoly constant-voltage\/constant-current charger to recharge them and at a rate of 0.25C (1.5A) or less.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eLike most lithium-ion packs, the batteries we sell do not have thermistors built in. This is why we suggest charging at 0.2C or even less - 1A max in this case. Of course, you can charge at a lower rate - it'll just take a little longer to fill up.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdditional safety notes:\u003c\/strong\u003e Do not use a NiMH\/NiCad\/lead-acid charger! Also, do not abuse these batteries, do not short, bend, crush or puncture. \u003cstrong\u003eNever charge or use unattended. Always inspect batteries and surrounding circuitry constantly for any damage, loose wiring, or possibility of short circuits.\u003c\/strong\u003e Polarity matches all Adafruit LiPoly\/LiIon chargers and boards, other brands may have reverse polarity and can destroy your battery. As with all Lithium ion polymer batteries and with any power source - they should be used by experts who are comfortable working with power supplies\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e3 x 2200mAh Lithium Ion 18650-sized cells in parallel\u003c\/li\u003e\n\u003cli\u003eDimensions: 69mm x 54mm x 18mm \/ 2.7\" x 2.1\" x 0.71\"\u003c\/li\u003e\n\u003cli\u003eWeight: 155 g\/ 5 oz\u003c\/li\u003e\n\u003cli\u003eMax charging rate: 1.65A\u003c\/li\u003e\n\u003cli\u003eMax continuous discharge rate: 3.3A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRevision History:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAs of 11\/11\/2014, these batteries come with a JST cable attached\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul id=\"product-files\"\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/product-files\/353\/353%20msds.pdf\"\u003eMSDS Report\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/product-files\/353\/C450_-_ICR18650_6600mAh_3.7V_20140729.pdf\"\u003eDatasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn-shop.adafruit.com\/product-files\/353\/18650_battery_pack_UN38.3__1_.pdf\"\u003eTest Report\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Others","offers":[{"title":"Default Title","offer_id":42292840923327,"sku":"MLE00850","price":400.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/893079e89217ce8175f95da186ee8485.jpg?v=1735814994","url":"https:\/\/makerlab.ph\/products\/lithium-ion-battery-pack-3-7v-6600mah","provider":"Makerlab PH","version":"1.0","type":"link"}
