In this video i finally decided to show you how IMPRESSIVE are these A123 cells. During the test, when the starter ran for about 2-3sec, the current reached 230A.

The GM volt wanted to use the same A123 brand and chemistry of these cells.

I never saw any smaller booster pack than this one that i built.. even though i searched on the www or in any stores.. so i believe that this is probably the most compact and powerfull boostpack in the world... They dont need to be plugged like 10 or 15 minutes like many "booster" conected to lighter plug....

This one can quick boost in less than 30sec.. just the time to connect it.. no need to wait!

For those who ask about battery mixing.. there is no problem.. their charge voltage is 14.4V (3.6V/cells) and this is the same common voltage of any alternator charging voltage. their charge and discharge profile (graph curve) one 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 SAFE battery.. no toxic.. no fire...

In this voideo i'm not trying to sale them.. I repeat: I just want to show people that the NEW Lithium battery are far away from the last that explode (Sony lithium cobalt.. like on the laptop or cellphone..)

Like for the SAFT battery, the army is using them too.

I know these A123 cells perfectly cause i tested them and i know every of their caracteristics. Just ask.. that will be a pleasure to me to tell you about them!

  • About the mixing.. ...

    About the mixing.. these battery are Lithium and are not permanantly connected to them.. just for burst boost. so there is no problem.
    their charge and discharge profile is one of the most similar to the SLA (lead acid) battery so paralleling them is ok. but NiMh or Ni-cad can not!.. you can not parallel any of these cells they can explode... A123 cells have no troubles with that. Like i said their internal resistance is very low and this is a great advnatage!

  • I Also read which ...

    I Also read which most ppl don't do, better to disconnect b4 starting. Just what I read. Also wondering if your little battery die right after the boost no? My 5 minutes is good for me, since u can fit in glove compartment. I got mine for 25$. Works With 8 cyl. engine. But mine only 6.

  • Yes, I saw your ...

    Yes, I saw your whole video the other day. It goes to over 13v in cuple seconds. I was just wondering about the battery mixing, was told they usually don't recommend connecting 2 completely different batteries together, cause it afects it life, is true? I use different batteries to boost and my battery is almost no good. has trouble holding charge. could just be defective..

  • I was not talking ...

    I was not talking about the lithium batteries, I was talking about the effect on the old generation floodies by mixing them.. Thats a nono. also me don't get your math. 3000cycles at 04A, then 1000cycles should be at 1.2A and 70A much less than 1000cycles, no? Big difference between 0.4A and 70A as you say...

    Their life is 3000cycles at 0.4A, 1000cycles for 70A and 300-500cycles for 120A 10sec burst... will someone need 300 jumpstarts?
    I dont think so..
