LIFE batteries
 

Do life batteries require a low voltage cuttoff like a LIPO.

RE: LIFE batteries
 

No they do not. I had several of the hobbyking LIFE batts and they were good while they lasted, which wasnt very long, maybe a couple weeks before all of them puffed. So if you are looking into the hobbyking ones look elsewhere.

I don't own any of the Hobby King LiFe batteries but there are quite a few of them in use at our field. No failures of any kind yet and this is well into their 2nd season. If all of your batteries puffed, I'd be looking at the charger settings.

Yes they do. If you take the HK life battery's down too low they will puff. I do find because they don't have the C rating of A123 lifepo4 cells you have to take them down to 2 volts per cell to get the rating out of them when discharging with out hurting them. My A123 cells stay at 2.5 volts or above.
HK life packs work great as Rx power but for motor applications I would stay with lipo.

I have 12 of the hk lifepo4 packs in use, 2 going on the 3rd year and all still work and charge fine for Rx power.

yes i think my dad uses a regulator

they work great for RX packs, my zippy pack is still going strong after a year, I don't use a cutoff but if you notice ANY drop off in power bring it in and shut it down because they go flat FAST and can leave you with a stuck open throttle.
