44v 10ah 440wh LTO 20,000 cycles! 20 cells! 48v

These packs are rated for over 20,000 cycles. You get 20 LTO cells in this pack. If you need a powerful pack that will work for most 48v applications this an amazing battery that will last an extremely long time.

This module comes with a lid that is glued on. You can run a screw driver around the lip or cut it with a dremel to remove the lid. There is also 6 bolts under the grommets on the bottom of the case.

These batteries usually have an issue with the relay or circuit board inside but the cells will test great. You will have to remove the outer casing to get to the cells. LTO cells can be discharged all the way to 0v without any issues.

Here are 48v 10ah packs that use 20 Lithium Titanate 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 100% capacity. All you need is a 20s 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 500+ amps on a pulse. This is truly a beautiful battery that'll likely last so long it'll end up in your will. 

Pack dimensions are 9" long, 6.5" wide, 7" tall.

If you are not familiar with LTO chemistry the cells can be fully discharged without damage and last over 20,000 cycles. 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 2.2v. So fully charged this pack will be 52v and fully discharged can be set to 44v but can go as low as 0.0v if desired.

The photo below shows the discharge curve of LTO cells.

Weight 23 lbs

Dimensions 9.5" x 8" x 7"

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. Makes this super easy, no soldering.
