Tenergy 5-in-1 Battery Meter, Intelligent Cell Meter Digital Battery Checker/Balancer for LiPo / LiFePO4 / Li-ion/NiCd/NiMH Battery Packs

A essential tool to have as a hobbyist that deals with lipo batteries on a daily basis. Works perfectly and is compact enough to slide in your pocket to take with you when you’re out with your RC! Super easy to use, you can check vital information on your lipos to help keep them maintained.

Good tool to have , well worth the low price

Works perfect for testing my batteries for my RCs quick test when I'm in field see where the batteries are at. I would recommend the b-6 charger if you're going to use this device to discharge a battery. I don't recommend using it to discharge it's not good for it. It is made to check the cells, and balance the cells if you do not have a balance charger.

It's ok. When I compare it to other meters, some voltage readings don't match up with the results from the other meters.

I have had similar testers which look almost identical to this one but come way short of capabilities this one has. As a designer myself, I would like to compliment that person for producing such a helpful tool! Everything functions as described, (Have not tested the servo drive part yet though) and the added features are very appreciated and useful! Internal cell resistance and battery balancing and the voltage difference between the cells works up to a very well designed product! I highly recommend this tester!

Works very well!! Really kool features to adjust servos

I have at least two other meters for measuring battery voltage and one that measure power also. But they don't read the internal resistance (IR) of my LiPo batteries. This one does and I think that is quite important for understanding your LiPo battery status and knowing when they should be retired. This meter provides that measurement for each cell. There are no instructions with the meter however, and I had to resort to YouTube to find how to use this - I might suggest you check out one of those before buying. There are other functions provided by this meter and I will need to do some exploration to see how to use those other capabilities. A simple link to some instructions would be very helpful. If you don't know how IR affects use, simply add up the IR for each cell (they are shown in mill-ohms) and multiply by the current you expect in operation. This will tell you how much voltage you drop at the battery. Take the square of the current times the IR total and that's what your battery looses as heat due to the IR. If the total IR for a LiPo averages more than 10 milli-ohms per cell, it's likely time for retirement. Note - you will see that the first and last cell are where most of the degradation happens. This is a good product, but some use information would be VERY useful.

This product wonderful. Now I can check my battery health and Status and doesn’t need to be charged. I’m impressed

Llego con agua el producto, lo dejaré secar y posterior checarlo

battery tester

I have several battery testers, but this Tenergy is the most useful. While many testers of the same style will only test the voltage of your cells or pack, this one offers some extras: - it can test the internal resistance of your lipo cells. - it can balance your Lipo packs. - It can discharge your packs (while this feature works, it should only be used for about 6 minutes, according to the manual, to avoid overheating). - it can test servos. Switching between these modes is pretty easy and the display will give you an indication of what mode you've selected using two/three letter words for each mode. In addition, it does provide these basic features: - lipo voltage alarm, which will beep when your set voltage is hit. To be honest, this battery tester is too large to be used as a voltage alarm in most RC vehicles, but it does work. - Can tell you the individual cell voltages. - It can tell you the min and max voltage for your cells. - It can give you the voltage difference between the highest and lowest cell. I've used this to test multiple LIPO packs (it helped to confirm that two were in need of being replaced) and several NIMH packs. To test a servo, you will need to connect a battery via a servo-style plug (made an adapter that connects to my deans plug batteries). The servo tester function is nice, and it works, but I prefer servo testers with knobs so you can also test servo speed with ease. Overall, this is a great battery tester, especially if you have LIPOs. It is compatible with other battery chemistry, like NICD and LIFE.

安いですし、使いがっても良いですが完璧に表示数値を信じるには微妙ですが・・・取り急ぎのバッテリー容量とセルごとの容量を知るには良いかと。

Such a handy tool for all my lipos. keep in mind you will need to have a servo Y harness that's not provided to use the servo testing facility. other than that, very handy
