It must only be used in compatible equipment with appropriate electrical and thermal protection. Incorrect charging, storage, installation or handling can cause overheating, fire or serious injury. Never short-circuit the cell, use damaged insulation, exceed safe operating limits or carry batteries loose. Tenpower specifies a 35A maximum continuous discharge rating; independent testing guidance recommends a more conservative 30A limit. Follow the manufacturer's latest specifications and applicable battery transport, storage and disposal regulations.\n\u003c\/p\u003e\n\n\u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"Tenpower","offers":[{"title":"Default Title","offer_id":68413336748422,"sku":"TENP40TG","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0697\/4239\/5675\/files\/TenpowerINR21700-40TG4000mAh-35A.jpg?v=1794421870","url":"https:\/\/www.londonvapewholesale.co.uk\/products\/tenpower-inr21700-40tg-4000mah-35a","provider":"London Vape wholesale","version":"1.0","type":"link"}
