The MS800 tester has a balancing function. The tester can balance a maximum of 36 modules simultaneously.

There is no separate function for this in the tester. However, in manual mode, the tester can perform several charge/discharge cycles, which can slightly restore the cell's capacity. If a cell has lost its capacity, it cannot be restored by any means.

We do not recommend diagnosing used modules this way. Such a test is performed on new cells at the factory for rejection. For express diagnostics of the module, you can measure the internal resistance. An internal resistance meter costs about $50, similar to a good multimeter. Our tester is primarily designed to measure the capacity of cells (Ampere-hours). In a healthy battery, this value should be the same for all modules.

Printing results is done from a computer using the TesterLogReader software, which can be downloaded from the official website. Data for printing is stored in the tester's memory. This data can be copied from the tester's memory to a USB flash drive and transferred to a computer. From firmware version HMI V1.011, a brief test result can be viewed by opening the test history in the tester.

Yes, but on the condition that one cell (element) with a nominal voltage of 4.2V is connected to one channel.

The main criterion for assessing the battery’s condition is the capacity of its modules. Our tester allows determining the capacity of battery modules. To determine the capacity, the following steps should be sequentially performed:1. Charge the battery modules to 100%.2. Discharge the modules to the minimum voltage for the given cell type. After the discharge is complete, the module’s capacity in Ah will be displayed on the screen.3. Charge the battery modules to 100%.
The battery is considered to be in good condition if three conditions are met:1) The capacity of the modules must be the same. Minor deviations are allowed. 2) The residual capacity of the modules must be greater than 80% of the capacity of a new module. 3) There should be no rapid self-discharge.

Yes, it can diagnose them. However, when diagnosing lithium batteries, it is important to correctly select the charge/discharge voltage. These are specified in the battery documentation. Generally, for LiPol it is 4.2V / 3.0V, for LiFePO4 it is 3.65V / 2.5V.
Important! The tester cannot discharge cells below 2.9V, but this does not hinder the diagnosis of LiFePO4 cells since the main capacity of the cell is above 2.9V. This is sufficient to check the battery on lithium iron phosphate cells.

Discharging with a low current gives a more accurate capacity measurement, which is very helpful when repairing batteries when the condition of their modules is unknown. High discharge current leads to battery heating, and high battery temperature, in turn, leads to capacity drop and can also completely disable it. Discharge currents in a car are quite high, so batteries are equipped with a thermal regulation system. Diagnostics are usually carried out without thermal regulation, so discharge currents should be lower than in a car. Moreover, the modules of a faulty battery are diagnosed, and in this case, discharging them with high currents is dangerous, especially for lithium-ion cells.
Our tester has 36 channels, they are galvanically isolated, i.e., they are not connected to each other, so two channels can be connected to one cell, thus we get 10A for discharge. However, it should be understood that in case of discharge with a current of 10A, the tester's overheat protection system may not respond in time, as it is designed for a discharge current of 5A.
