WhetEnergy 12.8V / 25.6V Wall-Mount LiFePO₄ Battery - 100Ah / 200Ah
Intro Paragraph
The WhetEnergy Wall-Mount LiFePO₄ series is designed as a drop-in replacement for traditional lead-acid batteries in residential and small commercial energy storage. Available in 12.8V (100Ah) and 25.6V (200Ah) configurations, these units combine a powder-coated steel enclosure with wall-mount installation to save floor space while delivering 6,000+ cycles of reliable performance.
Key Features
1) Direct Lead-Acid Replacement
- Feature: Sized and voltage-matched to replace standard 12V/24V lead-acid banks.
- Benefit: Upgrade without major system changes - compatible with existing non-communication inverters.
2) Space-Saving Wall Mount Design
- Feature: Heavy-duty sheet metal casing with powder-coated finish, designed for wall installation.
- Benefit: Frees up valuable floor space and protects the battery from ground-level dust or moisture.
3) Flexible Voltage & Capacity Options
- Feature: Standard 12.8V 100Ah and 25.6V 200Ah models; custom voltage/capacity available.
- Benefit: Adaptable to various small-scale energy storage or backup applications.
4) Advanced Battery Management
- Feature: JBD BMS with cell balancing and protective functions; optional Bluetooth monitoring via mobile app.
- Benefit: Greater safety and state-of-charge visibility compared to unmanaged lead-acid.
5) Long Service Life
- Feature: Rated for up to 6,000 cycles (5–10 years typical use).
- Benefit: Lower total cost of ownership with fewer replacements.
6) Series and Parallel Scalability
- Feature: Supports up to 4 units in series or 4 units in parallel.
- Benefit: Expand system voltage or capacity as needs grow.

FAQ
Q1: Can I install it in place of my existing lead-acid battery without changes?
A: Yes - dimensions and voltages are designed for drop-in replacement. Ensure charger/inverter charging profiles match LiFePO₄ specifications.
Q2: Why doesn't it communicate with the inverter?
A: Most lead-acid-based inverter systems lack communication ports. This battery is designed for compatibility with such systems, while still offering BMS protection and optional Bluetooth.
Q3: How does the wall-mount design help?
A: It saves floor space, keeps the unit away from dust and moisture, and makes wiring more accessible.
Q4: Can I expand my system later?
A: Yes, you can connect up to 4 units in series and/or up to 4 in parallel for higher voltage or capacity.
Q5: What's the warranty?
A: Standard 5-year warranty; extended coverage available upon request.
