Question.....I have read as much as I have been able to find on these life batteries and from what I can gather some say its ok and some say not to run these packs without a voltage regulator. Would that be correct? I have two life 1800mah 6.6v packs and I was going to plug both of these into my JR 9 channel receiver. I am running specktrum servo's A6010 and A6020 in 30cc gasser. About six servo's in total. Do I need a voltage regulator???

I've been running LiFePO4 packs (Hyperion brand) unregulated since last December. In addition I know a large number of others doing the same thing. So far I have not heard of anyone who has had a problem. The only potential issue is if you are using servos that simply cannot handle more than 4.8 volts.

If you have ever used a 6v Nimh rx pack you would notice that the voltage on it , fully charged , is high than that of the LiFe or A123 . Did you ever run a regulator with a 6v NiMh pack ?

Ive not run 6vnimh packs except maybe in my kadet senior with saito on it and a skyraider.
Neither of those have regulators.Most of what I have now are electric aerobatic planes.I do not use regulators on either one that i run the life pack in.for about a year or so now.
The life packs maintain a steady voltage while under load.Very nice.Only thing is this voltage holds until the pack gets depleted,then will nose dive so I hear.Ive not had one do this to me as I recharge after a few flights and noe the amount of mah goes back in,then compare to how many mah the pack is rated for.Then I kinda know how many flights I can have between charges..I have flown 8-10 flights on single charge on the flight pack before recharging..I usu go 6.

How do you test the voltage or whats left in the pack while at the field? I have been using Lipo packs and have no issues knowing how much power is left.

it is my understanding these packs hold steady volts until they are dead,then drop off rather quickly.So what I do,is fly about 5-10 times,then recharge and see how many mah i put back in my pack.Then I can kindof figure out how much I use durinf each flight.
I only charged my packs 1 time throughout a fly in this past weekend..

Cool to hear...
Some of the jet guys have been saying to only use true A-123. I know they are good but havn't seen anyone say the hobbico are bad

always good to hear feedback

A123's are great, but round and heavy.
