lipo for hyper transmitter

[froggy8]

hi guys, been thinking about getting a lipo instead of charging 8 batteries for my standard hyper 7 transmitter, could anyone point me in the right direction as to which lipo would work please?

 

cheers

Hi there,

I would assume an 11.1v would do as most i think will take upto 12v. is there a reason you want to go lipo? i only ask as it can be a chore,

first i think you may have to mod the tx unless the it already has a lipo connector

second you will want a voltage detector or cut off thingy to make sure it doesn't discharge to far, if you leave it on by accident you will kill it.

 

personally i would go for high rated mah nimh or even eneloop cells which have next to no self discharge and can be charged with a nimh charger.

you could even get a tx charger so you plug it directly into the tx to charge

 

cheers Ryan

cheers mate, i assume it has already got the lipo mod fitting as the whole battery case comes out making me believe that i could just put a lipo in there.

 

but just need to find which lipo though

I use one of my 3s cell from my losi truggy, only 180mah but out lasts my 2900 Nimhs an way lighter to hold

Does your radio have display for voltage? If not have to add an alarm with battery. What type of plug on battery tray?

What I use in hk310 with foam/sponge too keep cell in place.

cheers mate

 

this is the plug to my battery

 

 

and this is the socket on my transmitter

 

[R46]

exact same tray an plug as hk310 just play attention to poles of battery to tx

 

 

 

cell looks lost

 

 

[froggy8]

so if i get the same battery as yours then just plug it in my transmitter?

[R46]

Yeah just make sure plug is snug in port so not to loose connection,add an alarm if have no screen so don't go too low on volts

ok where did you get your battery from please?

 

also do i keep the lipo on storage and keep it connected to the transmitter or disconnect it and when i need my transmitter then charge it up?

[Noj]

Personally, I disconnect when not in use, and storage in between uses. My tx packs are a little larger mind, 1300mah, lol...always go big, IMHO of course

[Shudson]

Seems an awful lot of trouble, compared to NiMh.

[Noj]

Preferable to 8 AA's per handset, when you run an identical pair I run two dualports, and am shortly to be quad charging per charger anyway, so time taken isn't an issue

The true tx packs are low discharge, and, I have been 'naughty' and left them charged for a few days at a time, on occasion, with no degradation of cells thus far....

Just gotta be organized!

[Shudson]

But when you have 30 transmitters in fairly regular use and a further 20 used on odd occasions, messing around with storage charges and topping up and having to take batteries out to do it..........Much simpler, in my case, to have half a dozen or so trickle chargers (just plug into transmitter without removing batteries) and swap them to next transmitters every couple of days or so. Must admit that I have got LiFes in 6 of them (because they were cheapest option), but they are just charged every now and then and they take their chances. Even though I have facilities to charge 6 LiPos at once, it would be far too time consuming if all were LiPo.
