RedditBrand-level5.0 out of 10

Reddit owners split on LiTime and Ampere Time 12 V batteries. In an r/vandwellers thread an owner calls his Ampere Time 100Ah fantastic (July 2024), and replies in an r/SolarDIY thread on 24 V banks say LiTime batteries have been torn down many times and the build quality is excellent (March 2026). Against that, an r/boating owner's 100Ah lost its BMS after 10 cycles and LiTime, having agreed it was defective, stopped answering about the return (October 2025), and an r/OffGrid owner of 16 Ampere Time batteries reports BMS failures at 1.5 years and a support team that blamed his charging and wiring (January 2024).

No lifting-strap holes, per Notebookcheck
LiTime app not very impressive, per one owner

Notebookcheck, which LiTime sent the battery with its 3000 W inverter, 60 A charger and 60 A MPPT controller, found the 320Ah Mini compact and solid, its app's readings matched a clamp meter, its Bluetooth reached about 15 m and it ran a 400 W heater for over 9 hours near freezing, but it has no lifting-strap holes (October 2025). On DIY Solar Forum an owner running two in parallel as a boat's inverter bank said they have worked fine but found the LiTime app not very impressive (September 2025).
