BM200 Battery Tester & Maintainer
BM200 battery service instrument — 200W, 2–30V / 2–100Ah range, measuring voltage, internal resistance, SOC, SOH and true capacity (Ah).
Certifications
Key Features
- Four functions in one instrument — test, charge, discharge, maintain
- Test within 5 seconds: voltage, internal resistance, SOC and SOH
- True capacity (Ah) measured by a full constant-current discharge
- Programmable charge (CC/CV) and discharge (constant current + cut-off voltage)
- Automatic maintenance cycle recovers packs idle for over 6 months
- RS485, BM_Client software and multi-unit cascade for whole battery banks
- Pb-acid, Li-ion, LiFePO4, NiMH and NiCd — 2~100Ah, 2.0~29.4V
- Temperature-compensated charging with full protection (OVP/OCP/OLP/OTP, reverse, short)
Models
2 models in the BM200 series.
| Model | Voltage | Current | Protection | Applications |
|---|---|---|---|---|

Frequently Asked Questions
Can the BM200 test and charge the same pack in one session?
Yes — it is a four-in-one 200W instrument that tests, charges, discharges and maintains 2–30V battery packs from 2–100Ah, measuring internal resistance, SOC, SOH and true capacity in a single session.
What measurement precision does the BM200 offer?
Voltage ±1.0%, current ±2.5% and capacity ±2.5%. A fast test returns voltage, internal resistance, SOC and SOH within five seconds.
Can the BM200 record charge and discharge curves?
Yes — charge and discharge curves are recorded on the TFT and can be switched between graph and list view, supporting battery-health and maintenance reporting.
