Just to put this in perspective, for $169 you can get a 1200Wh deep cycle battery on amazon: https://www.amazon.com/Universal-UB121000-45978-100AH-Cycle-...

however, you will only get 300 cycles before the battery performance degrades to unacceptable levels.

If you wanted to use this deep cycle battery for 5 years (300X5, 1500 cycles), you would only be able to discharge 20%, meaning you would need 5 of them.

So given that you can buy a $169/1200Wh battery right now, and get 300 cycles Or you can consider it a $845 (5 X $169) / 1200Wh given the above explanation regarding cycles.

So for $900 you can get a 100 AH 12v lithium battery, which gives you near 1200Wh, $900/1200Wh to give further understanding about the title of the article. The lithium battery should give you the same amount of cycles as the 5 deep cycles. However they are relatively new in this size and unverified, they will probably perform at this level.

The 5 lead acid deep cycle's will weight approx 320 lbs, the 100 Ah Lithium Ion is 29lb...
