I use mine all the time for checking internal resistance, watching for a bad cell. Also the balance function works great, brings all the cells to the exact same. Better than my balance charger. Warning, don't forget about it while in balance mode, you'll find a dead battery a week later. I don't know what manufacturer mine is without looking. Because a buddy on mine has one just like it, and it does not have the internal resistance, or balance option. And yet, yours, mine, and my buddies, all look the same.

You can add a balance lead, but you MUST work carefully!! The positive and negative leads just go to the positive and negative output leads. The center lead goes to the jumper in the battery pack which connects the 2 cells. To reach this you carefully open the pack until you find the jumper and then solder the center lead to that. WARNING- even a somewhat discharged battery contains a LOT of energy and any short circuit will create an arc, heat, and likely damage the battery! I cover every metal part with tape except what I'm working on. That goes for knife blades too! Look for KZitem videos on this for advice. Balance lead/connector assemblies can be purchased online-you would need a 3 contact lead.

The Tenergy 5-in-1 has more features than the one that looks the same, but is named “Capacity Controller”. I don’t like that I have to push a button to see the voltage of the individual cells. I use the Hitec battery checker because it shows all of the cell voltages and the percent of charge on one screen without having to press any buttons. It lets me quickly check my batteries before connecting them to a parallel charging board. The Tenergy’s servo driver is handy, but the cell resistance function isn’t very accurate. It uses the 2-wire method where the load current and voltage are on the same two wires. It would be better to put the load on the discharge leads and measure the voltage at the balance connector.
