If verifying real measured capacity across all eight cells matters to you, plan to run them through CH1-CH4 in two batches of four rather than expecting all eight slots to test simultaneously.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"57:1-57:487;3809-4295\"\u003e\u003cstrong\u003eA realistic note on charge time:\u003c\/strong\u003e with all 8 slots occupied, the VC8's default charging current is 0.5A per slot (adjustable down to 0.25A if you prefer an even gentler rate). At 0.5A, a full charge for all eight 30Qs takes roughly 6.5-7 hours. That's slower per-cell than a 4-slot charger running at 1A, which is the trade-off for charging twice as many cells from one unit — CH1 and CH8 can individually push higher current (up to 2A or 3A) if you're not using all 8 slots at once.\u003c\/p\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\" data-sourcepos=\"59:1-59:35;4297-4331\"\u003eWhere This Bundle Actually Fits\u003c\/h2\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\" data-sourcepos=\"61:1-64:171;4333-4888\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"61:1-61:119;4333-4451\"\u003e\n\u003cstrong\u003e8-cell flashlights, lanterns, and larger DIY builds\u003c\/strong\u003e — devices or packs designed around a full set of eight cells\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"62:1-62:95;4452-4546\"\u003e\n\u003cstrong\u003ePower tool and e-bike battery packs\u003c\/strong\u003e where you're assembling from a larger verified batch\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"63:1-63:171;4547-4717\"\u003e\n\u003cstrong\u003eBuilders who want ongoing diagnostic capability\u003c\/strong\u003e — the VC8's grading mode (CH1-CH4) is useful well beyond this one purchase, for testing any future cells you pick up\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"64:1-64:171;4718-4888\"\u003e\n\u003cstrong\u003eMixed-chemistry households\u003c\/strong\u003e — since the VC8 also handles Ni-MH\/Ni-Cd cells (AA, AAA, C, D, etc.) with automatic detection, it can pull double duty beyond just 18650s\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\" data-sourcepos=\"66:1-66:48;4890-4937\"\u003eThings Worth Knowing Before You Use This Kit\u003c\/h2\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\" data-sourcepos=\"68:1-70:127;4939-5414\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"68:1-68:161;4939-5099\"\u003e\n\u003cstrong\u003eThe 30Q is an unprotected cell.\u003c\/strong\u003e The charger enforces its own voltage and current cutoffs, but your device still needs to handle discharge-side protection.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"69:1-69:188;5100-5287\"\u003e\n\u003cstrong\u003eDon't mix these cells with older ones you already own\u003c\/strong\u003e, even if they're also 30Q — run a batch through CH1-CH4's grading mode first if you want to check consistency before combining.\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\" data-sourcepos=\"70:1-70:127;5288-5414\"\u003e\n\u003cstrong\u003eOnly CH1-CH4 support capacity grading.\u003c\/strong\u003e Keep that in mind if you're planning to test all eight cells before a pack build.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 class=\"text-text-100 mt-3 -mb-1 text-[1.125rem] font-bold\" data-sourcepos=\"72:1-72:30;5416-5445\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"74:1-75:208;5447-5690\"\u003e\u003cstrong\u003eCan all 8 cells charge at once?\u003c\/strong\u003e Yes — all 8 slots operate independently and can charge simultaneously, though the per-slot current drops to 0.5A (or less) when all 8 are occupied, compared to higher rates available with fewer slots in use.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" data-sourcepos=\"77:1-78:234;5692-5985\"\u003e\u003cstrong\u003eCan this charger test the real capacity of all 8 cells?\u003c\/strong\u003e Only four at a time.
