[QUOTE="winkychevelle, post: 8801194, member: 611804"] It's all in the specs of the cells min/max voltage per cell. X the number of cells gives you the min/max charge voltage. People have been disecting the d4s and xs batts for a while. I used to think th xs batt was amazing but after seeing it cracked open it's lackluster. A decent battery but nothing amazing and the 5s is only for low voltage cars 14v and down because the Toshiba scib cells are 2.8v max each. 2.8v×5s=14v. The 6s is 16.8v max Pretty much all lto is going to be 14v max in 5s and 16.8v max in 6s Lithium iron phosphate lifepo4 run in 4s to charge at 14.4max though they have been proven to handle up to 14.6v. 4s lifepo4 also work well with agm since float voltage is 13.8v. Down side is lifepo4 has low c rating usually a max of 10 compared to lto which is typically 15c up to 70c in the best cells. Facebook has numerous lithium groups and several people who do loads of test as well as it's a hotspot for reported failures so you can learn from others mistakes. [/QUOTE]
