Great review. Could you please tell me if the leads are long enough to reach contact points about 60 cm apart?

I went out and bought one after watching this video. Much cheaper than the Noko versions. Hopefully just as good

Tidy Unit ,are those Croc Clips long enough to reach the biggest of Gaps between + & - on the Largest Batteries?

i made my own with proper lifepo4 high discharge capable cells , the cells i used are lithiumwerks anr26650 lifepo4 cells . i used 4 in series and 4 in parallel . each one of them can deliver 50amps cont and 150amp for 10sec's , 4 in parallel makes them do 600amps for 10 seconds and 200amps for as long as the battery voltage is above 10v. way better than any of these cheap power banks that use questionable cells. i started a full 5.8 24v cummins truck with this pack and it did not even hesitate . even with the grid heater plugged in which already draws 100-150amps when activated before starting. the whole pack is only 10ah but it starts a truck that requires 2x 800cca batteries and that is impressive. my clamp meter can not even measure the current draw , it was above 400amps. my toyota with 1.5l engine takes a peak inrush of 150amp . i just have a battery disconnect switch and active cell balancer . lifepo4 does not have any problem with 14.4v from the alternator because they charge at that voltage . but i disconnect mine asap because there is no current limiting for the charge and lithium battery has so low internal resistance that it can fry the alternator if i leave it charging without a charge controller to limit the current. and did i mention that i paid 10$ with shipping for all 16cells from batteryhookup!!!

Do you have any schematics of you starter?

[@andywheeler812]

Why are you mucking around with booster packs. For goodness sake go buy a new battery for your vehicle????

I don’t drive my car for months at a time. Sometimes I forget to put it on the trickle charger. New batteries go flat too with a car parked up for months with the alarm armed !
