Solar Battery Cost Comparison

Something that people fail to realize when comparing battery prices is the charge cycle life. A lithium battery lasts MUCH longer than a lead acid battery, so it is much cheaper in the long run. Below will give you a quick idea to how much each battery will cost you over time. The cost per kwh for 1000 cycles will give you the best metric to compare any battery!
​
​Sealed lead acid 8x 115 amp hour vmax batteries:
$2100 for 5.4 kwh for 1000 cycles
$388 per kwh for 1000 cycles
616 pounds
 
Trojan flooded 8x 105-s batteries:
$1300 for 5.4 kwh usable at 50% dod, 22 hour rate, for 1000 cycles
$240 per kwh for 1000 cycles
496 pounds
 
Battle born lithium iron phosphate:
$3600 for 4.8 kwh for 3000-5000 cycles
$150-$255 per kwh for 1000 cycles
116 pounds

Renogy Lithium Iron Phosphate:
​$3200 for 4.8 kwh for 3000-5000 cycles
$133-$222 per kwh for 1000 cycles
112 pounds
 
Diy lithium iron phosphate with prismatic cells:
$2400 for 4.8 kwh of cells, high quality bms cost can vary. Rated for 3000-5000 cycles
$100-$166 per kwh for 1000 cycles
114 pounds
 
2x Goal zero lithium 3000's:
$6000 for 6kwh for 500 cycles
$2000 per kwh for 1000 cycles
137 pounds
 
4x Inergy Kodiaks:
$7,500 for  4.4kwh for 2000 cycles
$852 per kwh per 1000 cycles
80 pounds
 
Tesla battery:
$1300 for 5.3 kwh for 5000 cycles
$49 per kwh for 1000 cycles
55 pounds
