-[[electrical:12v:deep_cycle_battery|Deep cycle batteries (Primarily lead)]] +With the prices of Lithium coming down to approachable levels, they are becoming more and more popular for all levels of build. There's two methods of obtaining a good lithium battery setup:
  
-[[electrical:12v:drop-in_lifepo4|Drop-in Lithium (LiFePO4)]]+  * Pre-built or "[[electrical:12v:drop-in_lifepo4|Drop-in Lithium (LiFePO4)]]" batteries. These are factory made batteries that you can (mostly) treat like any other battery; they're a sealed black box that already contain a Battery Monitoring System (BMS), safety cut-offs, and sometimes bluetooth monitoring. 
 +  * The more industrious (or frugal) can go the [[electrical:12v:lifepo4_batteries_thread|DIY Lithium]] path. This is where you buy the raw cells (usually at a deep discount directly from China), a BMS, cables, and bus bars, and build the battery packs yourself. Done properly, //massive// capacities can be had for prices so low it's not much more than a good lead battery setup.  
 + 
 +For those still pursuing lead chemistries, [[electrical:12v:deep_cycle_battery|Deep cycle batteries (Primarily lead)]] are strongly preferable.
