Hi Jeff polisena

If the battery doesn't have a balance lead, you can never balance the battery. I don't realy care how slowly you charge/discharge your battery, never balancing is asking to 'burn your house down'

That is not a true statement balancing does or doesnt cause fires miss charging or shorting out batt cause fires if you use proper charger and safe leads you should have no problems most people tell horror stories but they leave the part out about what they needed to modify to charge . If a battery manufacture did not put a balancing lead on their product then you should not have to worry about balancing

Its the slow discharge rate of the rx packs that enables them to not have to be balanced. TP packs can safely be discharged at 2 amps and charged at 4 amps or 1c depending on pack.

Thanx again for all the replies

I have the same belief as a few have stated on this thread.
If the 2S receiver batteries are used as intended, for receiver packs, then because of the small discharge rates, there is no need to balance them, hence they don't have a balancing lead. Thunder Power are one of the best, if not the best LiPo manufacturers in the world. That's why I'm happy to use them.

To clarify, I am using them in a Powerbox Gemini regulator, which is a top quality bit of kit, and the battery input to this is a male servo plug, as on the TP rx batteries.

I had a long chat with the top UK FAI pilot about what he uses. If they are good enough for him, they are good enough for me

Hi guys

I am sure TP knows what they are doing. Yes a Rx is 'light duty' compared to the power pack of an electirc heli etc. The funny thing is on another thread you will read about guys asking for the best regulator that can handle 10+ amps.

Lipo charging is dangerous and needs to be watched closely. I sold a Shock Flyer (small foam plane) to a friend for his son. It had small 3s 700mAh batteries and ran at less than 7 amps in flight. I sold it without my charger. They went and bought a 'non balancer' charging setup. A few months later, while charging the battery under his bed, unattended, the thing cought fire and burned the whole house down.....These were 'small' batteries used in 'light discharge' only.

Just something to think about.

Regards
Paul

I have a TP 2S 3400mah receiver pack without the balance plug, I'm thinking about cutting the JST plug off and putting a Deans plug on it to connet to a Arizona Dual Voltage Regulator which has a Deans plug already on it.

Which is the best receiver battery monitor to use when using these TP receiver packs without the balance plug? and would I have to make up a "Y" lead to connect the battery monitor between the battery and regulator?

I'm not using a TP receiver pack, ordinary Lipo.

I use a Deans plug between the regulator and Battery, no switches.
On the Male Deans plug, regulator side, I also wired in a
female servo connector for the voltmeter. This way I can unplug
the voltmeter and install in an unused receiver port etc. to
monitor the regulator output if need be.

You can program the voltage range on this voltmeter to monitor
the regulator input or the output. If you have a spare
channel, you can use it to log failsafes if digital or
glitches if analog.

If you already bought the TP, don't sweat it. I use the TP 3400mAh 2s2p Rx pack(w/o balance tap.) It works great. I was worried at first but it has been flawless. I tried it becuase it was 1/2 the price of an eqivilent FP pack.

T-Rex 450 SE V2 , T-Rex 600 NSP, Stryker F27 C....Yea, it's a plank.

yep, I've already brought the TP 3400mah pack (w/o balance tap.) but wasn't sure how to connect a battery monitor to it when running the battery through a Arizona regulator, or which battery monitor was best. maybe I'll try Stall Warnings idea.
