RX / TX batter tester?

Terry Keeley · Jun 19, 2016

Looking for a small unit, anyone use one of these?

Any other suggestions?

I use one of these. They also check LiFe.

Hi Terry,

Are you looking to test TX & RX packs? If so I use the Futaba BR2000, now replaced by the BR3000, my BR2000 iscapable of load tests of 1.0A, 2.0A & 3.0A and voltages of 4.8V, 6.0V & 7.2V. The new BR3000 may have more.

Thanks, John

It doesn't look like the BR3000 has load test capibilities, but looks like a nice unit.

Thanks guys, they both look good but nowhere did I see that they apply a load to the pack when testing?

Terry,

I called Tower and they changed the BR3000 - no load test. You might try to pick up a BR2000 on EBAY, I bought one for a friend last year in Hobart - like new for $25.00.

Thanks, John

Unless your still using NiCad or NiMh, I personally don't see the point in load testing (for RX/TX applications). The newer Lipo's and LiFe's voltage numbers are much less impacted by a load when compaired to the NiCad and NiMh cells. Especially in a low load conditions like RX/TX.

If you are still using "round cells" you might want to find a unit that John suggested. If you can't find one of the Futaba units, I have a load tester NIB. Problem is the unit I have is much larger in size when compaired to the Futaba.

Later,

Ball

Thanks. Found an old post says it's supposed to put 150 maH but actually draws 1a+!

Yup, and yup!

A buddy has this one, but it's discontinued:

We have a charger that tells us the Mah each charge puts in. Is there a tester that will give you the remaining Mah? When the packs are cycled the amount discharged and charged are both shown. Would be nice to know this info. By the way we use 6.0 volt NiMH packs.

Terry Keeley · Jun 20, 2016

Ya, just looking for a simple, small (pit box) tester that puts a load on the rx pack and reads voltage.

Hitec used to make one. I belive it was a 1A or 2A load tester. Its been a while since I used it. Been running lipo for a while now.

Terry Keeley · Jun 25, 2016

Thanks. Think I'm gonna go with the Prolux...

Got my Prolux a coupla days ago, works great! Does all types of cells up to 20v...

Nice little unit. Too bad is doesn't work on LiFe batteries.

That pic is of an older unit (2720), the one I got looks like this and does do LiFe as well (2721):
