if you add an extra battery you run the risk of loosing volts IF they are not the exact same kind of battery installed at the same time...... see my 2nd to last post - https://www.tamparacing.com/forums/s...03#post1312503

if you're alternator can keep up with the demands of the amp w/ out the cap then a 20 dollar cap wouldn't hurt IMO.....and it looks cool..... [/QU
having 2 diffrent batterys will not kill each other or loss voltage as long as they are charged when you put them in and if you kill one of them you use a battery charger it will be ok, i have 9 extre batterys in my van and it hasent had any effect that they wernt the same as the one in the front and that they were new and the one in the front was not. it doesnt matter OTE]
