12v Lithium Batteries for Beginners

The lithium batteries below are considered "Drop-in Lead Acid Replacement" because you can use them with standard 12 volt solar charge controllers/chargers/inverters and more. Simply hook them up to your system in the same way you would a typical lead acid battery. 

These lithium batteries out perform lead acid in every regard (even price!) and once you buy one, you will never go back. 
​​​Battle Born 12 volt 100 amp hour
​Lithium Iron Phosphate Battery
​
  • 1200 watt hours total capacity (1200 watt hours usable)
  • WEIGHT 31 LBS
  • SIZE 12.75 x 6.875 x 9 (L x W xH)
  • Lithium Iron Phosphate Chemistry (safest choice for mobile solar power systems)
  • 12 volt Drop-in Lead Acid Replacement (works with any 12v solar charge controller, but be sure to select the "sealed lead acid" charge setting)
  • 100 amp continuous output. 200 amp surge output
  • 3 year full replacement warranty and 5 year prorated
  • 3000-5000 charge cycles (cheaper than lead acid batteries in the long term)
  • Acceptable Charging voltages 14.4 to 14.6 volts
  • Recommended Solar Array Size: 100W-600W (parallel connect multiple batteries to increase the solar array size)
  • Has high AND low temperature protection (not common and very necessary! This is what sets the battle born apart from the competitors)
  • This battery CAN be series connected! Which means you can use it to build 12/24/48 volt systems

Keep this battery and all lithium batteries away from extreme heat/cold. Storing lithium batteries in a hot environment will decrease it's charge cycle life, and charging a freezing cold lithium battery will permanently damage it.

But! The battle born has a low temperature cut-off (the renogy battery below does not have this safety feature). This is why I recommend the battle born over the renogy battery.

These batteries are safe to store in your vehicles living area and do not require ventilation (but allow them to dissipate heat if possible for large discharge situations).

These are safe to parallel connect in chains (to increase capacity of your system) with standard battery cables. If you plan to power large loads, you will need multiple batteries (for each 1000 watts required, use 1 battery. Example: 4500 watt load will require 5 batteries wired in parallel).

The ideal charge profile for the battle born is the same as a 12 volt "sealed lead acid". If you have this option on your solar charge controller, select it.

​Renogy ​Lithium Iron Phosphate Battery
​
  • 1200 watt hours total capacity (1200 watt hours usable)
  • WEIGHT 28 LBS
  • SIZE 10.24 X6.22 X9.68 In
  • Lithium Iron Phosphate Chemistry (best choice for mobile solar power systems)
  • 12 volt Drop-in Lead Acid Replacement (works with any 12v solar charge controller, but be sure to select the "sealed lead acid" charge setting)
  • 100 amp continuous output. 200 amp surge output 
  • 3 year full replacement warranty and 5 year prorated
  • 3000-5000 charge cycles (cheaper than lead acid batteries in the long term)
  • Acceptable Charging voltages 14.4 to 14.6 volts
  • Recommended Solar Array Size: 100W-600W (parallel connect multiple batteries to increase the solar array size)
  • High temperature protection only (so do not charge this battery below 0 degrees Celsius. If you live in a cold location, use the battle born instead). 
  • ​Cannot be series connected! You can only parallel connect this battery so it will only work with 12 volt systems.​
