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.
