This lithium battery measures 170mmH 170mmW and 50mm thick and will easily start a 6cyl motor. The float voltage is around 13.3V (versus around 12.8 for lead acid) which turns the starter over a little quicker.Here is a pic and I did a youtube demo.www.youtube.com/user/turbotrana#p/a/u/1/JlRKIyUtvXEIts the black one on the right Edited 14/09/10 12:21 PM by turbotrana Link to comment Share on other sites More sharing options...

This one is fine. The car alternator charges it fine. This is largely experimental but I dont see problems yet. Yes it has balance taps.

turbotrana Member 2,586 Member For: 21y 5m 21d Gender: Male Posted 14/09/10 11:24 PM Author Share Posted 14/09/10 11:24 PM These batteries are not rated in CCA. It is a high discharge rate type lithium and if you watch the youtube video that shows me tuning the starter over for 10 seconds you will see that it spins the engine a little bit faster as this battery has a float voltage of 13.3V as opposed to around 12.8 for lead acid and around 12.4 for the Optima type.

I doubt the ford alt word be able to exceed the charge C rate.how do you plan to balance it? Link to comment Share on other sites More sharing options...

Its within specs of what the battery needs. Since its just a 4S style arrangement the balance bars seem to be OK. But if not there is another simple balance solution in the pipeline that does away with any complex BMS.
