Lifespan6.0

LiTime rates it for 4,000 cycles at 100 percent depth of discharge, scored ahead of its 6,000 at 80 percent and 15,000 at 60 percent, and one rung down because neither the spec table nor the manual publishes the remaining capacity at end of life, so it scores 6 on lifespan.

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).

GoogleBrand-level6.0 out of 10

On DIY Solar Forum a buyer's self-heating 12V 100Ah arrived punctured with liquid sloshing inside and LiTime refused the claim, which forum founder Will Prowse called unacceptable and raised with his LiTime contact (July 2024); in the same thread one owner's second set of four Group 24 Bluetooth batteries stayed within 1 mV of each other in series and another's self-heating battery has run a remote internet box flawlessly. The Gadgeteer, which LiTime supplied and which carries a 3% LiTime discount code, ran an Ampere Time 100Ah at about 22 A for over five hours, about 110 Ah (December 2022).

DIY Volts, which LiTime sent the self-heating 165 Ah at no charge, measured 2,106 Wh against 2,112 Wh rated on that sibling (December 2025).
