12v 10ah 120wh LTO LG Chem 20,000 cycles! 6 10ah cells!

These packs are rated for over 20,000 cycles.

Here are 12v packs that use 6 10ah LG Chem Lithium Titanate (LTO) cells in series. You know the new vehicles that turn off and restart every time you come to a stop? Well these are the batteries from those vehicles. We have opened and tested a few already and they test amazing since they never see a full cycle.

As shown in the main photo, you will receive the complete pack. You will need to trim around the plastic shell glue to get the pack out like you see it in the 2nd photo. The BMS is proprietary, you will need to use your own bms. There will be no voltage on the connections of the main housing as seen in the 1st photo. When you remove the BMS the pack inside will be balanced and have the voltage.

All you need is a 6s LTO bms and you are all set. Main positive and negative can be easily connected with ring terminals. The current busbars are designed for 130a continuous but can easily push 260a on a pulse. This is truly a beautiful battery that'll likely last so long it'll end up in your will. 

Pack dimensions in the plastic enclosure are 10" long, 7" wide, 3" tall.

Weight with enclosure is 7 lbs

If you are not familiar with LTO chemistry the cells can be fully discharged without damage and last over 20,000 cycles, Compare that to 300-1000 cycles for lithium ion and 2000 cycles for LifePo4. Fully charged each cell is 2.6 volts and fully discharged is typically 1.5v with the bulk of energy being stored between 2.6v and 2v. So fully charged this pack will be 15.6v and fully discharged can be set to 10v but can go as low as 0.0v if desired.

This is perfect for car audio but make sure you use compression if you are going to get over 100 amps.

The photo below shows the discharge curve of LTO cells.

LTO can be used even at -30 degrees Celcius.

Recommended max charge and discharge is 10c or 200a per cell. 

I'm sure you can take the cells out of the holder but I would recommend keeping the original busbars and spacing in tact. Its a professional connection that you can use. Just utilize the screw terminals to make your connections with wires and ring terminals.
