RedditBrand-level6.0 out of 10

Reddit evidence on LiTime's 48 V batteries is one thread. In r/SolarDIY (September 2024) a buyer of the 48V 100Ah server-rack battery hears they have been shown to be good batteries with a good BMS and grade-A cells, and an owner of three reports no problems while noting his units hold 15 cells rather than the usual 16.

Both testers found carry a tie. Brad Cagle, whose video is marked as paid promotion and to whom LiTime sent the battery and a charger, unboxed the 51.2V 30Ah battery, ran it down through an inverter and opened it to find large cylindrical cells in pairs, noting it cannot be wired in series (May 2024, about 6,200 views). Rinoa's Auspicious Travails, which LiTime sent the battery at no charge and which passes on a LiTime discount code, used it to power an electric bicycle sidecar and timed a charge of about seven hours at about 130 W (May 2024, about 4,900 views).
