Verdict — best value vs budget “The Fogstar Drift 105Ah ranks first here for one reason, and we would rather say it plainly: it is the only one of the three whose discharge, weight and warranty are published at all. The Renogy Core Mini is markedly cheaper per amp-hour (£1.70 against £3.05) and may well suit you better — but its range page states none of those three figures, so we cannot compare it on them. Cheaper per Ah is a fact; better is a judgement we are not in a position to make for you. A fourth battery, the Roamer SMART 105Ah, was dropped from this table: none of its figures could be confirmed on the maker's own page.”
