these are safe to keep in your radio?

I just got one of these life batteries to replace my lipo pack for my radio because i was sick of taking it in and out.... the life packs are safe to keep in your radios right?

Every pack is safe to keep in your radio, unless it malfunctions, or is charged in the wrong way.

Just don't trust lipos in the radio all the time!

Most if not all decent radios beep if no operation for a few minutes. Even if some don't, the most one can lose is just an overdischarged pack, it may puff, but no hazard.

Beaware that the DX7 and likely other transmitter can become scrambled if left on until battery become very low. If this happens they must go back to repaire center for fixing. I have not experienced this myself but I never leave my on by accident either but I have read of many such reports.

Guess I should add that I have used NiMH cells for years and years in my RC Transmitters and that for the past 4 years or so the LSD type mostly Sanyo Eneloops.

Or you could just sanyo eneloops then you don't have to worry about over working the regulator, removing the battery to charge, over discharge, etc, but still maintaining the very long sitting battery life.

Eneloops

If you are going to use a square cell technology I think this is a way better option than a LiPo.The voltage range doesnt hammer the regulator either.The low voltage alarm is still in the correct range as well.LiFe packs tend to stay balanced better than LiPo but its still a good idea to balance charge.

Don't trust NiMH as well. This happend to a friend's plane when the charger failed to stop charging the RX battery.
Could as well happen to your TX.

NiMH s AKA Eneloops in a Transdmitter charge just fine with the OEM Wal Wart chargers which do not depend on peak detections. Any charger can fail but in 49 years of flying RC I have never had the first problem with these low tech supplied with the radio systems chargers.

There is no need in using a peak detection charger with a RC Transmitter Ni battery unless you need a fast charge at the field due to poor planing on your part. A 1 Amp. rate charge at the field for 15 min. will give you between 1 and 2-1/2 hours of addational transmitter on time depending on your radio.

I had an old Cannon wall wart TX/RX charger suddenly burn up while I was in the room. Seemed to be a short where the wires exited the plastic case although hard to tell after the fact. I wonder if a bad pack or leaving connected too long can cause a wall wart charger's output wires to overheat melt and short.
