About this item

  • 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.

Product Description

Tenergy 5-in-1 Cell Meter has 5 main functions: capacity checker, battery balancer, battery discharger, battery internal resistance tester, and ESC/Servo PPM tester

Package includes

  • 1 x 01444 Tenergy 5-in-1 Cell Meter for LiPo / LiFePO4 / Li-ion / NiCd / NiMH Battery Packs
  • 1 x User manual

Battery Capacity Checker

  • Tenergy 5-in-1 Cell Meter can display the estimated capacity and voltage for LiPo / LiFePO4 / Li-ion / NiCd / NiMH battery packs. Use this function to quickly check if your battery requires charging before use. For LiPo/LiFePO4/Li-ion packs, it can also display the voltage of each cell, so you know when they need to be balanced.

Battery Balancer:

  • Optimize your battery’s performance, and extend the overall lifespan, by ensuring the individual cells are balanced.

Battery Discharger:

  • Discharging your battery prior to changing can improve the runtime of your battery. Tenergy 5-in-1 Cell Meter can discharge lithium-based battery packs to an adjustable threshold, at the discharge rate of 180mA.

Battery Internal Resistance Tester:

  • For lithium-based battery packs, this cell meter can display the internal resistance of each individual cell, so you can evaluate the health of your battery pack and decide when to discard or replace it.

ESC/SERVO PPM Tester:

  • Supply a reliable PPM signal to test and adjust your servo motors.
  • *Note: A Y-harness and 4.8V-6V NiMH battery (not included) is needed to support ESC/Servo function.

WARNING

  • To avoid overheating, the discharge function can only be used for less than 6 minutes each time. After that, let the unit cool down to room temperature before discharging again.
  • DO NOT leave your battery discharging with this device unattended.

NOTE:

  • Tenergy 5-in1 Cell Meter uses the test battery as a power source (does not require outlet adapter).
  • Li-ion/LiPo/LiFePO4 hobby battery packs NEED a balance connector in order to be tested.
  • NiMH/NiCd battery packs NEED a Hitech/Futaba connector, or an adapter, in order to be tested.
  • Li-ion/LiPo/LiFePO4 battery packs without a balance connector CAN NOT be tested.

Heat is an issue.
3 Stars
Heat is an issue.
So, I got this unit because I build custom batteries for ROVs. I needed something to balance the cells because it's very often that I end up with 1 or 2 cells that are .1-.2 volts off from the others. The issue occurs because the batteries I make are from 25,000-35,000 MAH, which is HUGE in comparison to the batteries in the video. This means that it takes upwards of 2 hours to balance. The result is that this thing gets insanely hot and completely defeats the purpose of the balancer. It works but I don't feel comfortable with it.The solution was to use two layers of heat tape and a piece of aluminum sheet to sink the heat away from the resistors. It works well now.The only other gripes I have are that the battery percentage is corrupted and never displays correctly. This doesn't matter much but is sub ideal. The other thing is that the per-cell voltages can vary by .05 volts which is kind of annoying. I'm very precise about my voltages.
