Izinhlobo ezintsha ze-Heltec zokushisela izindawo zinamandla amakhulu ngamandla amakhulu we-max peak pulse angu-42KW.Ungakhetha ukuphakama okuphezulu kusuka ku-6000A kuya ku-7000A.Idizayinelwe ngokukhethekile ukushisela ithusi, i-aluminium kanye neshidi lokuguqulwa kwe-nickel, uchungechunge lwe-SW02 lusekela ithusi elishubile, i-nickel ehlanzekile, i-nickel-aluminium nezinye izinsimbi ezishiselwe kalula futhi ziqinile (ukusekela i-nickel plated copper sheet kanye ne-nickel ehlanzekile yokushisela i-electrode yethusi yebhethri, ithusi elihlanzekile. ishidi ukushisela okuqondile kuma-electrode ethusi ebhethri ane-flux).
I-HT-SW02H futhi iyakwazi ukukala ukumelana.Ingakwazi ukukala ukumelana phakathi kocezu lokuxhuma kanye ne-electrode yebhethri ngemva kokushisela indawo.
