The Vti 24V 200AH LiFePO4 battery pack is a high-performance, deep-cycle lithium iron phosphate battery designed to replace lead-acid batteries in solar, UPS, and inverter systems. With a 200A BMS, it offers enhanced safety, longer lifespan (3,000+ cycles), and 90% depth of discharge. Its lightweight design and stable thermal performance make it ideal for renewable energy storage.
What Is a 7.4V LiPo Battery and How Does It Work
How Does the Vti 24V 200AH LiFePO4 Battery Compare to Lead-Acid Batteries?
Unlike lead-acid batteries, the Vti LiFePO4 battery provides 3x longer lifespan, faster charging, and 50% weight reduction. It operates efficiently at 90% depth of discharge versus 50% for lead-acid, doubling usable capacity. The built-in 200A BMS prevents overcharge, overheating, and short circuits, eliminating maintenance requirements.
In solar applications, the Vti battery maintains consistent voltage output even during prolonged cloudy days, whereas lead-acid batteries experience voltage sag below 50% charge. For example, a 24V lead-acid system might drop to 22V under heavy load, triggering inverter shutdowns, while the LiFePO4 variant stays above 24V until fully depleted. This stability allows users to utilize 95% of the rated capacity without damaging the cells. Field tests show the Vti model retains 85% capacity after 2,500 cycles compared to lead-acid’s 40% degradation after just 800 cycles.
What Safety Features Are Included?
The 200A BMS provides 11-layer protection: overcharge/over-discharge cutoff, short-circuit recovery, and cell balancing. UL1973-certified casing withstands 1.2m drops. Thermal runaway prevention activates at 80°C. IP65 rating protects against dust/water ingress—ideal for marine installations.
Choosing the Right Charger for a 200Ah LiFePO4 Battery
The multi-stage safety system includes cell-level temperature monitoring that samples data every 50 milliseconds. During a simulated short-circuit test, the BMS interrupted current flow within 200 microseconds—60x faster than industry standards. The flame-retardant casing (UL94 V-0 rated) prevents fire spread, and the pressure relief vents maintain structural integrity during thermal events. For marine use, the IP65 rating ensures protection against saltwater spray and humidity fluctuations between 10-90% RH.

|---|---|---|
| Cycle Life (80% DoD) | 3,000–5,000 | 500–800 |
| Weight | 49kg | 130kg |
| Charging Efficiency | 98% | 75% |
“The Vti 24V 200AH model disrupts the solar storage market by offering industrial-grade BMS at consumer prices. Its 200A continuous discharge supports high-demand appliances like air conditioners—something rare in sub-$2k lithium batteries. We’ve seen 94% capacity retention after 1,500 cycles in field tests.” – Renewable Energy Systems Engineer, PowerTech Solutions
FAQs
- Can This Battery Be Used in Series for 48V Systems?
- Yes—up to 4 units can be series-connected for 48V/51.2V systems. Use manufacturer-recommended cables and confirm inverter compatibility.
- Does Cold Weather Affect Performance?
- Charging below 0°C requires low-temp protection. Discharge works to -20°C with 15% capacity reduction at -10°C.
- Is External Heating/Cooling Needed?
- Not for standard use. Built-in thermal management activates only during extreme temps. For Arctic/Arid climates, consult the installation manual.
