Supercaps and lithium, reliable in a daily?


Recommended Posts

Open ended question. Are Supercaps and lithium (LifePo4) safe to run in a daily driver? 

 

My current idea is to delete my underhood battery and turn it into a distribution center essentially. 

Then 86 my AGMs and replace it with a 25 aH / 45aH limitless lithium (Limitless seems like it has acquired JY power, so new JY batteries are probably unlikely). 

I was thinking of running a super cap to ease the load of starting the car on the lithium, would it be better to place this nearest to the amplifier (between amplifier and lithium) or have it upfront in the stock location?

 

 

 

Some background on car: Civic 08 / Daily driver / Amps: RF 600x4 + DB AAK 4000.1D powering a SP4 15 dual 1

I did 6 banks and a 40ah juice box lithium for almost 2 years without issues

8 banks of blue Maxwells + 260ah of Yin Long LTOs 

2 370 Amp Autotech Alts 

mids amps 2  Crescendo Skyway 3ks

sub amp: 4 Crossfire XT 8ks

Subs: 8 18 in Crossfires in a 4th order

How did you have your batteries setup?

No upfront battery, Jbox and caps in rear?

Supercaps charge and discharge at a fast rate so they aren't great for continuous loads. And lithium does not do well underhood or in harsh environments without a cooling and/or heating system included. 

If either of those bother you then sick with agm. I've been following some development with super/ultra caps we are doing at my work and there it's becoming a hard sell for the OEMs so I've been hesitant to recommend them in long term applications.

Correct no front battery with jbox and caps rear

Real magic happens when you get enough Alt power and ditch batteries and run strictly caps

If you plan to run agm and lithium together, know that lithium rests at a higher voltage and the agm will be drawing off it kind of negating the lithium benefits except for the weight. 

Don't do this...Delete AGM/Lead acid and run lithium...Trust me I lost an Alternator this way

I've been running my entire car off a 45ah Limitless for quite awhile including feeding juice to my system as well so yeah it works :)
