lithium battery VS lead-acid battery:
1. Different nominal voltages: single lead-acid battery 2.0V, single lithium battery 3.6V;
2. Lithium battery has higher energy density, lead-acid battery 30WH/KG, lithium battery 110WH/KG;
3. The cycle life of lithium batteries is longer, with an average of 300-500 times for lead-acid batteries, and more than 3,000 times for lithium batteries;
4. The charging method of lithium batteries is relatively fixed, and the voltage-limiting and current-limiting method is adopted, that is, a limited threshold is given for both current and voltage, while there are many charging methods for lead-acid batteries;
5. Lead-acid batteries are safer to use, and the cost of construction is relatively low;
6. The source of the difference between the two is based on the performance of the materials. The positive and negative materials of lead-acid batteries are lead oxide, metal lead, and concentrated sulfuric acid; lithium-ion batteries have four components: positive electrode (lithium cobaltate/manganese acid). Lithium/lithium iron phosphate/ternary), anode graphite, separator and electrolyte;
Product Advantages:
1. Iron Phosphate-lithium Battery Powerwall :80% DOD , More than 2500 cycle times
2. Long warranty period:2 years
3. Higher energy density,smaller volume for household.
4. Max 4 in series and up to 6 in Parallel.
5. Photovoltaic system:this battery pack is designed for household photovoltaic systems.
6. Battery management system(BMS):the battery packs built-in BMS monitors its operation and prevents the battery from operating outside design limitations.
7. Expand ability: this battery pack can be easily expanded by adding expansion battery packs in parallel connection.
