No clue about them but there's another company that has a 2.5 lbs lypo battery that can be charged with the stock charging system. I'll look for tge link later. It has more CCA then our stock battery

 

It's a very new company, started only a few months ago. I also noticed the stock charging system problem - interested in that battery josh

 

hey,

I think I got these two batterys comfused. One is the 2.5lbs one and the other is the 4.93lbs one. The 4.93lbs one is the lipo battery that charges on the stock unit and has more cold cranking amps then the stock battery.

5lbs-

I'm running the deka etx14L and have no problem starting the car, even in the winter, and playing the radio for 45 mins then trying to start the car. If you copy the specs of the etx14 you could run this shorai battery..

1.8LBS- http://www.batterystuff.com/powerspo...14A1-BS12.html -2 more AH and 10 more C.C.A then my current battery
2.1LBS- http://www.batterystuff.com/powerspo...18A1-BS12.html -overkill compared to my current battery. 6 more AH and 70 more C.C.A

Both of these ^^ have better specs then my current 14LBS battery and will charge with the stock charging system.


good luck.... The 2.1 is on my short list for next year. I'll take the extra .3LBS to know I'll have "overkill" specs compared to what I use now.
