LiFePo4 cells

For the 2012 model

LiFePo4 cells

Postby Otello on Mon Feb 17, 2014 5:04 pm

I have a PTW CQBR MAX (2012) with M130 and M150 cylinders
I am looking for LiFePo4 batteries and found few options, but want to make sure that it is safe for the PTW:


1) M130 cylinder with LiFePo4 9.9V 2000mah 15C (like Powair6 9.9V 2000mah 15 C Lifepo4 custom battery for PTW crane stock)?
2) M150 cylinder with Firefox 12.8V 1350mah (like Firefox 12.8V 1350mah LiFePO4 battery)?

You are perfectly safe using either of those batteries.
However you might find the M130 works better with the 12.8v as the 9.9v might be a little under powered.

But you will be fine using those battery types ;)

got some experience with Firefox 12.8V 1350mah - it works OK with M130, but it does not work at all with M150.

To add a question/experience to the topic if it's ok with TS.
I have 9.9V 1000mA 15C with an M90 (@340fps) and FCC 3.0. Tested it at home and I find it surpring that it looses power fast if you shoot in single shot. Not enough peak A? Would i be better of with a 11V lipo 1200mA 20C?

15A is quite low, even for an M90
The lipo will be up there at 24A, which is fine for any cylinder

I find it easier to just have one type of battery for all my cylinders (M130, M150 and M90)
