The Best Lithium Ion 12V Deep Cycle Batteries

LiFePO₄ batteries or (lithium iron phosphate batteries) are a new type of lithium-ion battery.

LiFePO₄ batteries offer many advantages over lithium cobalt dioxide (LiCoO2) batteries which are commonly used in laptops and cell phones.

In electric vehicles, LiFePO₄ batteries offer greater range, power and safety. They provide full power until they are completely discharged, and recharge in just 2.5 hours.

LiFePO₄ chemistry is also environmentally friendly — it’s the least toxic of all the battery types. They do not contain toxic heavy metals such as lead, cadmium, nor any corrosive acids.

Here are the LiFePO₄ batteries currently available on Amazon:

• Mighty Max LiFePO₄Battery — 100 Ah — 30 pounds — $675
• TalentCell LiFePO₄ Battery — 100 Ah — 26.4 pounds — $700
• BattleBorn LiFePO₄ Battery — 100 Ah — 29 pounds — $950

Here’s a list of all the advantages of LiFePo4 batteries:

• LiFePO₄ are safe — they do not catch fire or explode with overcharge
• They have over 2000 discharge cycles life compared to typically around 300 for lead acid
• Double the usable capacity of similar amp hour lead acid batteries
• Virtually flat discharge curve means maximum power available until fully discharged (no “voltage sag” as with lead acid batteries)
• High discharge rate capability, 10C continuous, 20C pulse discharge
• Unlike lead acid batteries, can be left in a partially discharged state for extended periods without causing permanent damage
• Extremely low self discharge rate (unlike lead acid which will go flat quite quickly if left sitting for long periods)
• Can be used safely in high ambient temperatures of up to 60C without any degradation in performance
• Maintenance free for the life of the battery
• Can be operated in any orientation
• LiFePO4 cells are of solid construction — there are no fragile/brittle plates made of lead which can be prone to failure over time as a result of vibration
• Can be safely rapidly recharged — when fully discharged can be brought to a state of over 90% fully charged in 15 minutes
