Product Description
Newest Optimum 12V LiFePO4 batteries provide the most reliable start-up power supply for mini hybrid vehicle

Detailed imformation as below:

The mini hybrid car stop-start system requires without doubt that its start-up batteries must have performances and functions of big usable capacity, high specific energy, high specific power, long cycle life, deep discharge, discharging with big current, fast charge and discharge etc. Traditional lead acid batteries obviously occur fatal bottlenecks in many aspects, it's wise to choose LiFePO4 start-up batteries.

Optimum developed OBC-12V20Ah(able to replace current 12V/36Ah-80Ah lead acid batteries) and OBC-12V30Ah(able to replace current 12V/60Ah-120Ah lead acid batteries) LiFePO4 start-up batteries.

1. Light, small; Lighter 60% than lead acid battery with the same size;
2. Usable capacity is big, up to 99%, but traditional lead acid start-up batteries is 50%-60% in general.
3. Superior performance of deep discharge, charging and discharging with big rate; Instant discharge current is big, start performance at high and low temperature is good;
4. Cycle times can be up to 2, 000, keeping 5-year life, with design of special protection function;
5. Competitive price and superior quality, highest cost-effective in lithium power batteries.
6. High stability and safety;
7. Green and environment-friendly: Main composition of LiFePO4 can be used as soil fertilizer after breaking up, high performance and no pollution.
Comparison between LiFePO4 battery and Lead-Acid battery:
BatteryIngredientsLiFePO4 BatteryLead-Acid 
Safety & Environmental ConcernSafest; no explosion; no smoke; no fire under very bad working condition; most environmentally friendly; non-toxic; no rare metal, fire resistant, easily disposed is acceptable; heavy pollution to water and soil; breaking ecological balance; threatening people' s health especially for Children; hard to dispose of; high re-use cost.
Life CycleBest, up to 1000 times under 80% DOD(theoretically 2000 times)  Very short life cycle, about 150 times under 100% DOD; maintenance needed very often.
Long term CostMost economicalCost of whole lifetime is higher than  LiFePO4
Thermal PerformanceExcellent – Can work normally under -20° C~70° CThe capacity decays quickly if the temperature is higher than 50° C
