The two cell LIPO is an excellent replacement for the six cell NICD pack, it will not exceed the voltage recommendations ( @ 8.4 max ) for the FEDEC, I run my 20 years old TJT300 that has a Xicoy FEDEC with a two cell LIPO.
My first turbine was a 2300 Simjet, I run it with NICD packs, we used to run all of our turbines with six pack NICDs then we switched to 2 cell LIPO packs when they became available, we still do, I run 3 of my engines on a 2 cell LIPO pack.
