Description of Tenergy 5-in-1 Battery Meter: Intelligent Cell Meter Digital Battery 🔋 Checker & Balancer for LiPo, LiFePO4, Li-ion, NiCd, NiMH Battery Packs

Multi-purpose battery meter - The Tenergy 5-in-1 cell meter estimate voltages for LiPo/LiFePO4/Li-ion (2-7 cells) packs and NiCd / NiMH batteries for TX and RX (4-7 cells). The battery capacity checker requires no additional accessories and is powered by the testing battery pack to quickly evaluate the pack's capacity. Battery discharger - At the discharge rate of 180mA, the battery balancer discharger can discharge lithium-based battery packs to an adjustable threshold. By discharging your battery prior to charging will improve the runtime of your battery. Balances batteries - The battery tester with balancer function helps to optimize your batteries performance and extend the overall lifespan by ensuring the individual cells are balanced. Internal resistance tester - For lithium-based battery packs, the battery internal resistance tester function will display the internal resistance of each individual cell. Use the battery checker tester to evaluate the health of your battery pack and decide when to discard or replace it. ECS/Servo PPM tester - The Servo tester supplies a reliable PPM signal to test and adjust your servo motors.

Does what it says in electrical document

Works great. Cheap, easy to use. Can be used as an on-board counter if desired. The discharge is slow, the IR meter isn't very accurate, but it's accurate enough to tell if the lipo is bad. Only balances cells in the 010 ohm range, if the cells are below this the meter will not balance them until they exceed a constant 010 ohm reading but the IR digital display will jump between 001 and 003 ohms for milliseconds back and forth which causes the balancer showing the wrong ohm value therefore…

Pros
  • ECS/Servo PPM Tester - The servo tester provides a reliable PPM signal for testing and adjusting servo motors.
Cons
  • Good but not great

Nice addition to my Li-Ion and LiPo gear

I needed a way to control individual parallel groups while the Li-Ion battery was dead and after problems with the type of LED that alternates between elements I decided to do something more to pay and get this item. I have a Tenergy TB6B four button charger that I am very happy with, so I chose this brand. Voltage readings are accurate compared to my multimeter, and the balance function can give an even more accurate result than my charger based on user-selected criteria. The alarm function…

Pros
  • Internal Resistance Tester. For lithium batteries, the battery internal resistance check function displays the internal resistance of each cell. Use a battery tester to assess the condition of your battery and decide when to discard or replace it.
Cons
  • Cable is shorter than other options

Turns out I needed it more than I thought

I originally bought this meter to quickly and easily discharge end of life batteries completely before discarding them. Turns out I use it regularly now to balance the items after charging. Some chargers are much better than others at completing a charge cycle that charges every battery cell to the same level. The Syma X8C charger doesn't handle this very well as it works well up to a certain level and then stops charging one cell at a time. If I catch it in time it's fine, but if I let go…

Pros
  • Battery Balance. The Balanced Battery Tester helps to optimize battery performance and extend battery life by balancing individual cells.
Cons
  • Doubtful

Good value for money internal resistance meter

I have at least two other battery volt meters and one that also measures power. But they don't read the internal resistance (IR) of my LiPo batteries. This is true and I think it is very important to understand the condition of your LiPo battery and determine when it should be taken out of service. This meter provides this measurement for each cell. However, there are no instructions for the gauge and I had to turn to YouTube to find out how to use it - I would advise checking one of these out…

Pros
  • Multipurpose Battery Meter - Tenergy 5 in 1 cell meter evaluates voltages for LiPo/LiFePO4/Li-Ion batteries (2-7 cells) and NiCd/NiMH batteries for TX and RX (4-7 cells). The battery capacity tester requires no accessories and is powered by a test battery, allowing you to quickly assess battery capacity.
Cons
  • So-so
