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
​
My favorite drop-in lead acid replacement. I have tested every battery on the market and this is a solid choice (I have used 2 in my main system for 6 months). If you want something that works great for years, buy this battery. I have not heard of a dissatisfied battle born battery buyer (not the case with most of these drop-in replacements). It just works.

  • 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 "LiFePO4" or "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: 14.1 to 14.6 volts
  • ​Has high AND low temperature protection 
  • This battery CAN be series connected! Which means you can use it to build 12/24/48 volt systems

If you want this battery to last a long time, keep it in a cool environment. The Battle Born does not require ventilation and it is maintenance free, but having a little air flow in your battery compartment can help keep the temperature down and prolong the life of your battery. 

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).
