Right thats me new battery saved up for and on order
Be lot smaller than me other PSU been using by about 6Kg LOL
Not cheap but will do job nicely
Now save for the charger LOL currently not in stock and man enough to supply the battery as advised by Hobby King. And yes stay on page for short while and few quid do get knocked off price.
My sota gear is getting closer to what I want to use and light weight
Congrats to your new batteryâŚ
I am using it now for abt. 3 years. I always treated it wellâŚi.e. charging with balancer and not too high amps.
But I donât want to disappoint youâŚ
the last 12 month it starts swelling up ( about 20% in size) as you can see on the picture.
Mine started some minor swelling, but not that much. Been using it for a little over two years now. The LifePo4 is a totally different animal than the Lipo battery. That being said, mine never leaves its case.
yes, on top of that I recommend buying an inexpensive -LiPo safe bag- and keep the battery there all the time (even if LiFePo4 seem tobe safest than LiPo).
If it flames you wonât damage the rig or yourselfâŚ
I learnt from the local radio control shop Penn Models that itâs really important to use the Storage cycle on your lithium battery charger. This was after the second LiPo had started to grow and swell. These batteries should not be left fully charged for prolonged periods otherwise the chemicals have no space in terms of charge if they get warm or hot whilst in storage or transit. Fully charged in a hot place and they swell.
Extension leads for the balance lines are available at your RC model shop . That makes it easy to connect battery in its protective bag to the balance ports. Powerpole connectors 30 or 45 amp as the interconnection twixt radio and rig means youâre most likely to be able to help each other on a joint activation.

I have been using this kind of battery for 2 years now with great success. They pack a lot of power in a small package and I use the smaller version (4200) with my KX3 all the time. I even made a benchmark to see for how long it can keep up in almost continuous operation. So this chart show that the battery can sustain for 2 hours and a half a cycle of 10 sec. transmit and 10 sec. listening. For the KX3, this correspond to 2.4A in transmit mode and 200mA in receiving mode:
Karl,
I installed two sets of Powerpole connectors on my 4200 LiFePO4 battery. The one in the background is a 1500 mAH battery I use as my spare spare.
Hmmm just seen when battery is in relation the the radiator on the wall, too close must find better place when heating goes on laters this year. Prop can it in Shed in metal box be nice cool storage then.
Done exactly the same here⌠be careful not to short out the battery when fitting the new connectors⌠I was exceedingly careful⌠didnât fancy the âbangâ that might ensue!
Agreed on that one Gerald
Especially this one is a 8500mah.
What intend to do now is get a box good plastic one and fit in couple banana posts in female into box and connect to the battery.So once in there it stays in there. as then banana males can be used to contact from the 12v Rig power leads straight in to the Main PSU under bench reducing risk of the big bang. And also line base of box with anti slip stuff i have, and some foam squares to cushion it in side, donât want it rattling about now do we during transport.,
Now can you buy the longer balance leads as one on battery is bit short in it
The rating of that battery is apparently 30C which means the peak current it can source is its rated capacity in AH multiplied by 30. Thatâs in the vicinity of 250 amperes, enough to start a small engine, and capable of melting almost any wires that might stray across your binding posts. For this reason I would not use binding posts, they are too easily reached by bits of wire, especially in the dark, when working in a hurry, or when someone else connects their rig to your battery. Anderson powerpoles (or the larger, higher rated series) have the advantage that the terminals containing all that potentially destructive energy are well concealed and you cannot drop wires across them accidentally to cause trouble.
Powerpoles are best crimped, not soldered. You can purchase the relevant jaws (rather than the tool offered by Powerwerx as one example) and attach them to a generic tool.
When fitting any connectors, do one at a time, leaving the old connector on the red while you reterminate the black, or vice versa. An extension for the balance lead can be purchased from Hobby King.
