Aux Starter Capacitor

I am looking at a snow trip, usually base camp for a couple of days or 3, deep in the snow. I am always concerned about battery voltage and starting in the sub zero tempos especially when everything is so cold, so decided to invest in this 1300amp capacitor starter pack that sits attached to the main battery. The starter motor is supplied off this device and has an operational limit of minus 40 DegC. Good for 500,000 starts they claim as an operating life, no lithium, upper temp threshold of 80 degC - thats above what I have measured under the bonnet previously.Attachment 89203
It can be removed from the vehicle and used to just start a second vehicle as long as that dead vehicle battery is above 5VDC. It can be used to start a vehicle without a battery, however may not sustain the running requirements of some of the electronic controls.

What about a foot pedal generator if that drains too?

Are you trying to be clever? I have a wire cage with lamas rotating around an alternator stator o ensure they stay both warm and the camp has lights. I am a solution provider.

Clever? Me? Never, but at least you'll get warm while you pedal your heart out to recharge the capacitor!!

The charge time is 4 hrs on a 5V USB supply and 1 hr on a 12V alternator supply from flat, or so the claim is. I hooked it up today in its as delivered state and on the car charger clamped to the battery, it topped up in 30 mins. Its got a bluetooth function that i managed to not fuck up and it shows base battery capacity, capacitor storage state of charge, voltages, and some other stuff. Its a crank battery back up and preserver I guess, not dissimilar to the portable jump start packs I think. Time will tell if it delivers the marketing blurb.

This is why I have the 4 lamas to do the recharge - not even going to feed 'em.

Remember a few years back your computer screen would be filled with conversations like this, I miss that, wish facebook would close down and people would come back here.

Something I see over here more often now are cars with start/stop systems. Once on a stoplight, the car shuts down the engine to save fuel and once the driver takes the foot of the brake pedal, it restarts, but quite quick it seems. I've been told that these systems don't crank from the battery otherwise it would reduce drastically the battery life span.

That said, did it crank you engine faster?

You could be right as it's possible in peak hour congestion I guess for dozens of stop start. Having said that the battery guy we got out for the wife's car mentioned batteries are being installed with larger capacities also for all the background electronic stuff going n

Times change, people move on, but I hear you

I've sometimes considered using a 16v supercapacitor, have seen them work effectively on 12v solar setups handling inverter surge loads.
