1. longer life, up to 2000 cycles(while Sealed Lead Acid batteries only 750 cycles and NiMh batteries only 500cycles) 2. higher capacity and voltage (we can install many many single cells in series and in parallel, and it can fully discharge,while SLA batteries only 70% to fully discharge) 3. more powerful (high discharge current, 2C continuous, 5C pulse for normal cells and 25C for special design) 4. safer(never explode and stable in high temperature, so no temperature controller needed) 5. lighter, and smaller(1/2 size/weight of SLA batteries, 70% size/weight of NiMh/NiCd batteries, ) 6. totally environment-friendly(no lead or cadium at all) 7. no memory effect(it can be recharged anytime, no reduction of the capacity) 8. wide operating temperature(-40~75℃) 9. rechargeable by solar power
