I've been looking to upgrade my DIY battery bank to a custom battery box. When LiPULS reached out about their 280Ah 12V LFP battery, I saw the perfect opportunity to test a compact alternative to running multiple 100Ah batteries in parallel. In this review, I put this battery through real-world testing using a Victron Smart Shunt and the XiaoXiang BMS app to see how it actually performs for preparedness and off-grid use. What I Cover: ✅ Unboxing and specs breakdown ✅ Why one 280Ah battery vs. three 100Ah batteries in parallel ✅ BMS protections and what the 200A rating actually means ✅ XiaoXiang app walkthrough - cell voltages, balancing, and BMS data ✅ Victron Smart Shunt monitoring - real capacity measurements ✅ Load testing at 1100W and 650W (the 0.2C rating standard) ✅ Actual usable energy: DC vs. AC after inverter losses ✅ Honest pros, cons, and cost-per-Ah comparison Key Specs: Capacity: 280Ah (3,584Wh nominal) Chemistry: LiFePO4 (LFP) Voltage: 12.8V nominal BMS: 200A continuous Cycle Life: 4,000+ cycles to 80% capacity Warranty: 5 years (10 years with registration) Size: 19" × 6.7" × 9.4" Weight: 61 lbs with handles Self-discharge: ~3% per month This is an early look at a budget-friendly LFP option for preppers and DIY solar builders. I'll be using this battery for the next year and will provide long-term updates on performance and durability. Coming Soon: Full DIY battery box build tutorial - subscribe so you don't miss it!
