Lithium battery questions

Recommended Posts

1st questions i plan on running 12k rms  and i noticed that the XS15k and XS30k are the max rating and the continuous are half the max. So does that mean i would have to get a XS30k for my 12k rms system or will the XS15K be good enough. And what the difference between the spl version and non spl 

2nd question I started to look at some post about them and I noticed someone said that they were informed by XS Power that the battery perform best at 11.8v. Is this true?  This information kinda threw me off because I don't like going below 12v. That makes wonder where the the 16v version perform best at. 

3rd questions how will they handle mixing with agm batteries? I currently have 2 xs power battery a D5100r and a D2400. And I also will be buying a charger. I was going to buy a XS Power PSC15 but I also noticed XS have lithium chargers. Can i charge them all together or separate or delete the agm batteries? Will it matter if I used the PSC15 for the lithium battery, or is it a must that i get a lithium charger?

4th question be honest with me, do you guys really think it's worth getting lithium battery. And do you think the other companies lithium battery like jy or limitless are good?

5th question is not a lithium question, just don't feel like making another post for this simple question. But my D2400 crack on the side and leaked from it. I removed it and put my voltmeter on it read 12.6v and it did well on a load test. So I just put glue on the crack and put back in the car. Should I be worried about it. I've had that battery since 2011

I'd suggest looking into a lifepo4. I just found a company this morning that has them priced way cheaper than expected. They did a head to head against my power and held up better than the my power.

lithium is definitely where its at if long term demoing is your goal, for SPL its not the best but will work because the voltage does stay in the 12's, with continuous output, rather than caps which have output at a higher voltage but voltage drops off quicker. 


as for your other questions, lithiums are fine paired with AGM batteries, they just have mildly different floating voltages so when your vehicle is off the lithium will be drained down to battery level, but its not a problem as long as you have a good alternator. also you can charge lithium with a regular battery charger, but unlike AGM, you cannot leave it to "maintain" the battery, they need to be charged then taken off the charger since they can be over charged and become volatile. you just have the watch the voltage and take it off once it reaches peak charge voltage, a lithium battery charger will simply know when to stop so you dont have to watch it, along with cycle the battery for you to keep it alive longer

XS Power batteries are LifePo4 lithium.

Thought I remember someone saying they weren't.

Im sure someone did. The misinformation is incessant.

I know on one post I said I didnt think they where, but in the same thread I later said I was wrong.

They never advertise what they where and I couldnt find out until a month ago while talking with Scottie.

The XS Power batteries have crazy protection built into them, unlike other brands being mentioned.
