This kit pairs one BigBattery HUSKY 2 48V battery with a 3K Growatt inverter, built as a package for off-grid systems, backup power, and mobile setups like RVs, camper vans, and food trucks. The data provided by the manufacturer for this listing does not include detailed cell-level specifications, so several technical fields below are flagged as unverified rather than guessed.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
Why This Matters
A battery-and-inverter kit like this is meant to simplify sourcing for off-grid and mobile power projects: one battery, one inverter, sized to work together. That said, the buyer still needs to confirm the battery's capacity (Ah/Wh), BMS discharge limits, cycle life, and operating temperature range before wiring it into a system — none of these were included in the manufacturer data supplied for this listing. Treat the unknowns below as open items to verify with BigBattery directly, not as implied specifications.
Battery Characteristics
Chemistry: LiFePO4 (Lithium Iron Phosphate) — based on the "HUSKY" product family designation and lead-acid replacement positioning. [NEEDS VERIFICATION] for explicit chemistry confirmation, as the source data does not state it directly.
Voltage: 48V nominal, per the product title and stated design intent ("Designed For 48V Applications").
Group Size / Form Factor: [NEEDS VERIFICATION] — not provided in source data.
Capacity (Ah / Wh): [NEEDS VERIFICATION] — not provided in source data.
Wiring & Configuration Limits (Series/Parallel)
The manufacturer data for this kit does not specify maximum series or parallel expansion limits for the HUSKY 2 battery. [NEEDS VERIFICATION] before wiring multiple units together or combining with other battery models. Do not assume compatibility with other BigBattery product lines, other voltage batteries, or lead-acid batteries in the same bank without confirming with BigBattery first.
Pro-Installer Tip
Series and parallel limits on lithium battery banks are set by the BMS inside each unit, not just by wiring — exceeding the rated pack count can trigger BMS lockout or push individual cells out of balance over time. Before adding a second HUSKY 2 unit or connecting this kit into a larger bank, confirm the documented series/parallel limit in the manufacturer's manual. Verify pack balance and voltage with a shunt-based battery monitor before and after any expansion, and keep planned depth of discharge in the 80-100% DoD range typical for LiFePO4, rather than assuming lead-acid-style 50% DoD limits apply.
Key Benefits
- Packaged as a matched battery + inverter kit, reducing sizing guesswork for a 48V system.
- Marketed for lead-acid replacement in off-grid, emergency backup, RV (Class A/B/C), camper van, food truck, commercial vehicle, and mobile power applications.
- Includes a 3K Growatt inverter as part of the kit (inverter-specific specs not detailed in source data — refer to Resources tab).

Compatibility & Fitment
This kit is positioned for 48V off-grid systems, emergency backup setups, and mobile power in Class A, B, and C RVs, camper vans, food trucks, and commercial vehicles.
It is NOT confirmed compatible with series/parallel expansion beyond what is documented by BigBattery — do not wire additional HUSKY 2 units or third-party 48V batteries into this system without verifying limits first. Standard lead-acid battery chargers are NOT recommended for a LiFePO4 pack; use a charger and charge profile matched to lithium chemistry. This listing does not include a UPC/GTIN from the manufacturer, so none is provided here.
FAQ
What voltage is this kit designed for?
This kit is built for 48V systems, pairing the HUSKY 2 battery with a 3K Growatt inverter.
What is the battery chemistry?
The HUSKY line is positioned as a lead-acid replacement, consistent with LiFePO4 chemistry, but the manufacturer data provided for this listing does not explicitly state the chemistry. Confirm with BigBattery before purchase if this is critical to your application.
Can I add a second HUSKY 2 battery to this kit later?
Series and parallel expansion limits were not included in the manufacturer data for this listing. Verify the documented limit with BigBattery before wiring in additional units.
Is this kit suitable for an RV or food truck?
Yes, per the manufacturer's stated use cases, which include Class A, B, and C RVs, camper vans, food trucks, and commercial vehicles.
Does this kit include a UPC or GTIN?
No UPC/GTIN was provided in the manufacturer data for this listing.
