Ultracapacitors, Are they worth it?,...

[5022]

I have had Maxwell ESM in my last two trucks . It has been a real game changer for me. I had agm in the first and regular batteries in the present truck. I my opinion the maxwell is a bigger plus for the way I run than the agm. I spend every other night in truck but only for ten hour break and turn for home on relay. Regular batteries run espar and coolant heater just fine so far. I screwed up once on new truck changing fuel filter but even then in ten minutes it cranked and started. I only made that mistake once. It is always nice to know you always have a start in the maxwell no matter if the batteries get pulled down or not.
