MS800A Battery Module Tester and Balancer

MS800A Tester & Balancer for Hybrid and Electric Vehicle Battery Diagnostics

The MS800A tester is used during the repair of high-voltage batteries in hybrid vehicles. The tester can determine the capacity of nickel-metal hydride (Ni-Mh) and lithium-ion (Li-ion) batteries of various types: NMC, NCA, and LFP. The battery module diagnostic and balancing process occurs automatically. The tester incorporates protective systems to prevent battery module damage during diagnostics.

The MS800A stores all measured data during the battery module diagnostic and balancing process in its memory. This data can then be reviewed and analyzed on a PC using the TesterLogReader software, which you can download and use for free.

Capabilities of the MS800A

• Diagnoses high-voltage battery modules, determining their capacity.
• Charges sequentially connected cells of batteries that become unbalanced over time.
• Prepares the battery for installation in the car by balancing all modules by voltage.
• Prepares modules for storage by charging them to a certain level.

Key Features

• 12 independent, galvanically isolated battery module test (balancing) channels (Ni-Mh or Li-Ion).
• Automatic operating mode.
• Battery module protection against:
  • overcharging/discharge;
  • overheating;
  • incorrect connection (wrong polarity).
• Saving diagnostic results.
• Convenient viewing and analysis of diagnostic results.
• Management and control of the diagnostic process through a touchscreen.
• Free software update.

Technical Specifications

Built-In Protection

The MS800A incorporates multiple protection systems designed to protect both the tester and battery modules during diagnostics:

• Reverse polarity
• Short circuit
• Overheating
• Overcharging
• Over-discharging

The MS800A is suitable for professional EV and hybrid battery repair workshops requiring automated module testing, capacity measurement and balancing of multiple battery modules simultaneously.
