NSTL has a tender for supply of 5 units of Li-ion battery packs with battery management system:

So each battery pack has 13 cell & each cell can produce 480 W of electric power. Thus total power is (480 x 13)= 6240 W = 6.24 kW

This new Li-ion battery is a lab scale test battery. This is the 1st time we willbe using Li-ion batteries to underwater applications. For comparison the Silver Oxide Zinc battery used on the ALWT has 70 kW power. The Varunastra has 250 W Silver Oxide Zinc battery.

The submarine launched version of the Varunastra (called the EHWT) with have an upgraded 300 kW Silver Oxide Zinc battery. That battery is under prototype testing:

Maybe a scaled up version of the Li-ion battery can be used on the upcoming Jalastra torpedo.

The above packs are for ALWT. They seem to be revising the design again. The other project with Lithium packs is the HEAUV (High Endurance Autonomous Underwater Vehicle). Very high activity in the HEAUV tenders nowadays.

Won't the submarine performance suffer?
Why would it suffer? The torpedo is above average but not the best..
If they could get economy of scale and batch by batch improvements. It will be a quite a successful export product. But we need a torpedo in the class of the British spearfish.
