- Higher energy density. They can store significantly more energy in the same space/weight.
- Longer cycle life. They can provide 2-3 times as many cycles as lead acid batteries.
- Can accept a high charge current until nearly completely full - no absorption phase is required. This allows allows more rapid and efficient charging during the limited daylight hours when the PV source is operating or when running a generator.
- Higher round trip efficiency. 95-98% as compared to 80-90% efficiency for lead acid batteries.
- Higher depth of discharge. 80-100% with each cycle is possible as compared to recommended maximum of 50% with lead acid batteries.
- Voltage is not very responsive to temperature, which means that lithium ion batteries perform better in warm temperatures. Temperature compensated charging is not required.
