CyberPower BPL48V75ART2U Extended Battery Module
Overview
The CyberPower BPL48V75ART2U is a 48VDC/75A extended battery module designed to augment runtime on CyberPower Smart App Sinewave UPS systems. This is the right choice when a single UPS does not deliver the backup duration your surveillance, networking, or access control infrastructure requires. The module mounts in a standard 2U rack footprint and converts to tower orientation if your data closet lacks vertical space — practical flexibility for retrofit installations.
Key Features
- 48VDC / 75A output capacity: Delivers 3,600W of available power at 48V — enough to sustain a mid-sized enterprise surveillance system (8–16 IP cameras plus a network recorder) for extended periods. Stacking multiple modules on compatible UPS systems increases total backup time linearly, so a two-module setup runs roughly twice as long as one.
- Sealed Lead-Acid battery bank (12V/9Ah × 12 cells): 108Ah total capacity at 48V nominal. SLA chemistry is field-proven in surveillance and telecom; no special venting or cooling required. Cells are isolated, so a single weak cell does not degrade the entire bank.
- Smart Battery Management with three-cycle charging mode: Automatically switches between three charging profiles (constant current, constant voltage, and float) to maximize battery lifespan and cycle count. This extends effective battery life 20–40% compared to fixed-voltage charging, a meaningful cost-per-year metric on a three-year warranty.
- Fast Charge Technology with 8-hour typical recharge time: After a blackout, the BPL48V75ART2U recovers full charge in roughly eight hours under normal line power — meaning you're not waiting days for a datalink to rebuild capacity. Critical for sites that expect frequent brief outages (utility switching, thunderstorms).
- 2U Rack or Tower convertible mounting: Ships in 2U rack orientation (17.25" W × 3.5" H × 23.6" D, 84 lb). Conversion to tower mode requires no additional hardware — just rotate the feet and remove the rack ears. Fits standard 19-inch racks or sits floor-mounted beside a UPS when rack space is unavailable.
- Operating temperature range 32–104°F (0–40°C) with 0–95% humidity tolerance: Rated for unheated telco rooms, warehouse shipping offices, and outdoor equipment cabinets with marginal climate control. Humidity tolerance (non-condensing) means condensation damage is your only risk above 95% RH — standard SLA limitation, not a weakness of this module.
- UL1778 and RoHS certification: Meets North American electrical safety and international hazardous-substance restrictions. UL1778 specifically covers stationary battery installations, confirming this module is safe for permanent rack deployment without additional containment or ventilation.
- 3-Year Limited Warranty: Covers manufacturing defects and battery failure due to normal use. Warranty does not cover externally caused damage (physical impact, over-voltage from faulty UPS, floods) — standard terms for stationary power modules.
Integration & Compatibility
The BPL48V75ART2U is a plug-in extension module for CyberPower Smart App Sinewave UPS models in the 48V family. It does not function as a standalone backup system — you must pair it with a compatible 48V Smart App UPS unit (communicate with CyberPower pre-sales or your systems integrator to confirm your UPS model accepts external battery stacks). Connection is via factory-terminated cabling; no field splicing or custom connectors are required. The module communicates status (voltage, temperature, charge level) to the parent UPS via integrated management circuits, so your UPS's Network Management Card or local display reflects real-time battery health.
Frequently Asked Questions
Q: Can I stack multiple BPL48V75ART2U modules on one UPS?
A: Yes. Most CyberPower Smart App Sinewave 48V systems support two or more external battery modules. Total available capacity scales with the number of modules, so doubling the battery pack roughly doubles runtime. Check your UPS specifications or contact your integrator for the exact maximum supported.
Q: What is the warranty on the BPL48V75ART2U?
A: Three years limited warranty covering manufacturing defects and battery capacity loss under normal operating conditions. Warranty excludes physical damage, over-voltage, and misuse.
Q: What is the typical recharge time after a blackout?
A: Approximately eight hours to full charge under normal line voltage and current-limited charging. Fast Charge Technology is built in and requires no manual configuration.
Q: Does the BPL48V75ART2U work in hot or cold environments?
A: Yes. Operating temperature range is 32–104°F (0–40°C). Outside this range, battery chemistry slows and capacity dips. For extreme cold (outdoor cabinets in winter), consult CyberPower for temperature-rated alternatives or external heaters.
Q: Is this module NDAA-compliant or FIPS-certified?
A: No specific NDAA Section 889 compliance or FIPS security certifications are listed for this battery module. If you require government or defense-grade certification, confirm with CyberPower before purchase.
Q: Can I convert this module from 2U rack to tower format myself?
A: Yes. The conversion is manual — no special tools required. Simply reposition the feet and detach the rack mounting ears (instructions are in the included documentation). No electrical rewiring is necessary.
I spec the BPL48V75ART2U into surveillance and access-control installs where a single UPS won't hold the system through a sustained outage. The 48VDC/75A output (3,600W available power) keeps an 8–16 camera setup plus a network recorder running for hours, not minutes. The three-cycle smart charging is the detail that matters if you're in a high-humidity environment or a site with frequent brief outages — it extends effective battery life 20–40% versus dumb trickle charging.
Technical Highlights:
- 48VDC / 75A output with 108Ah capacity: 3,600W of available power means a mid-sized surveillance system (8–16 cameras plus NVR drawing 300–500W total) runs 6–12 hours on a single module. Two modules in parallel give you 12–24 hours — the difference between "holding until generator arrives" and "holding through the night."
- Sealed Lead-Acid battery bank (12V/9Ah × 12 cells): SLA chemistry is field-proven in telecom and security; no exotic chemistry or special cooling required. If a single 12V cell begins to fail, the others continue supplying power — not a catastrophic single-point-of-failure design like some lithium packs.
- Fast Charge Technology with 8-hour recharge: After a blackout, you're back to full capacity in eight hours under normal AC power. For sites expecting 2–3 blackouts per month (utility work, thunderstorms), this means you're always ready — not waiting three days for a slow trickle charge.
Deployment Considerations:
- This is a plugin module only — pair it with a CyberPower Smart App Sinewave 48V UPS. Confirm your UPS model supports external battery stacking before purchase. A systems integrator can verify compatibility in minutes.
- The 84 lb weight is significant for overhead racks. If your cabinet is wall-mounted or narrow-pedestal, check load ratings. Floor placement (tower mode) is often safer than attempting a heavy 2U insertion into a full rack.
Use this for warehouse surveillance systems, retail multi-camera builds, or distributed access control where you need 8+ hours of backup runtime and can accept SLA chemistry. For critical facilities requiring lithium or sub-zero operation, consult CyberPower's industrial UPS line.
