A123 Worlds Smallest VS. “Strongest” 12V Jumpstart battery
Posted on 28 May 2012 by smokeandtoke6123
In this video i eventually made the decision to display you how Extraordinary are these A123 cells. During the test, when the starter ran for about two-3sec, the present reached 230A. The GM volt desired to use the same A123 brand and chemistry of these cells. I never saw any smaller booster pack than this one particular that i built.. even though i searched on the www or in any retailers.. so i feel that this is possibly the most compact and powerfull boostpack in the planet… They dont need to have to be plugged like ten or 15 minutes like several “booster” conected to lighter plug…. This 1 can rapid increase in much less than 30sec.. just the time to connect it.. no need to wait! For people who inquire about battery mixing.. there is no problem.. their charge voltage is 14.4V (three.6V/cells) and this is the identical common voltage of any alternator charging voltage. their charge and discharge profile (graph curve) 1 of the most similar than SLA (lead acid)… Nicad or NiMh can not do that… they can explode… the A123 can not explode.. just search about: “A123 Nail test” on youtube you will see… they are Protected battery.. no toxic.. no fire… In this voideo i’m not trying to sale them.. I repeat: I just want to show men and women that the NEW Lithium battery are far away from the final that explode (Sony lithium cobalt.. like on the laptop or cellphone..) Like for the SAFT battery, the army is employing them as well. I know these A123 cells completely lead to i examined them and i know every single of their caracteristics. Just ask.. that will be a …

This is awesome. Kudos to you sir
nanotech beat the A1q23 as well.. but not in cold condition…lipo are made to operate without permanent damage down to zero celsius.. not below… A123 have been tested and tested and tested by big compagny and they are up to the task for cold temp.
I started a old subaru outback floded under 2 foots of snow with the alternator jamed in the rust and this little cold 2.3Ah pack succeded to start this veru cold engine! ( lead acid oem battery was dead.. and more acting like a load !
You obviously have never played with good lithium batteries. Go look up Turnigy Nano-Tech batteries. I use them and they live up to their specs. 360 amps constant from a 6 amp hour cell. They pack a punch for their size.
@Doctorbass Is it possible to use the A123 batterypack to replace the heavy lead carbattery?
Could it be charged off the alternator?
I’m asking this as I’m looking for ways to make my car lighter.
So where are the improper remarks are?
also these cells can produce huge current (amperage)
another fool! who does not know that horsepower and torque are the same ! look it up on google:)
horsepower is just torque multiplied by the rpm
Don’t mix up everything… Actualy Horsepower refer to Watts, not voltage. Voltage refer to torque and amps refer to speed. You can have as much torque as you want, if nothing moves you don’t produce any power also you can have as much voltage as you want you don’t produce any watt if you don’t have any amps. If you need 200A at 12V to start your engine, this meen that you will need 100A at 24V. Your WRX will just need to rev at a higher speed to do the same work
This video went viral on Castries
That’s not correct. Lithium batteries won’t last 2000 charges if you drain them down below 11V like you’re doing here. They only last 2000 charges if shallow-discharged. LA batteries will last 3000 cycles if discharged shallow. Think about it — the typical car is started 500+ times per year, and the battery can easily last 5+ years in a moderate climate.
yeah that’s a great idea but have you tried lipo battery which have way more amp than Ni-mh
Awesome!!!
These kind of lithium cells can last for 2000cycles compare to lead acid ( 200 cycles) they can be cdischarged at 60C ( 140A) each cell and be charged at 4C ( 10A)
but since this pack is not built to stay connected to teh alternator, it does not really matter for the few second it is connected to it
Surely that cannot be good for the cells? Lead acids are built to give huge current short term to start the engine. I would have thought the combination of cracking the engine and then high charge current from the alternator would destroy them.
