Qidianfy 24V 200Ah LiFePO4 Battery vs ECELL ELIS24200 LiFePO4 Battery

Both are 24V-class 200Ah LiFePO4 batteries with about 5.12 kWh, so the real split is the BMS and the cells. The ECELL ELIS24200 has the stronger electrical spec: a 200A continuous discharge with a 400A peak burst and an IP65 ruggedized ABS case. The Qidianfy claims EV-grade cells rated 6000+ cycles and a low-temperature charge cutoff, but its own listing says the BMS is 200A while a buyer note calls it a 200A unit under 60% C rate, and its rating rests on only 11 reviews. Buy the ECELL for high-draw loads and wet or rough mounting; buy the Qidianfy only if you trust its cycle-life claim and want low-temp charge protection.

• Choose the Qidianfy if you want low-temperature charge protection and a claimed 6000+ cycle life, and your loads stay well under 100A continuous.
• Choose the ECELL if you need a 200A continuous discharge with a 400A peak burst and an IP65 case for marine, RV or outdoor installs.
