When your golf cart, RV, camper van, or mobile worksite needs a power source that keeps up not one that slows you down the BigBattery 48V HUSKY 2 PWR Lithium Battery 5.12kWh 100Ah is purpose-built for exactly that mission. This isn't just another battery upgrade. It's a rugged, intelligent, high-density energy system engineered to perform where ordinary power sources tap out, whether that's a sun-baked fairway on hole 14 or a frozen trailhead at 6 a.m. in November.
Built on Tier 1 LiFePO₄ (lithium iron phosphate) chemistry and paired with an advanced Battery Management System, the HUSKY 2 PWR is the high-power (PWR) variation in BigBattery's 48V lineup. Unlike inverter-communication-dependent ESS configurations, this battery is designed for flexible, standalone integration making it the go-to choice for 48V motive power applications, mobile equipment, and standalone energy setups that need reliable juice without the complexity. Ships from Texas, USA and backed by a 12-year warranty and lifetime USA-based tech support, it's a power investment that works as hard as you do for years to come.
With 100Ah of lithium energy, you get enough power to run your golf cart, RV, or mobile equipment all day long no mid-day recharge needed, no frustrating slowdowns when you need performance the most.
The built-in Battery Management System watches over every charge and discharge. It automatically stops overcharging, overheating, and short circuits before they cause damage protecting both your battery and your equipment around the clock.
Most lithium batteries struggle or get damaged in freezing temperatures. The HUSKY 2 PWR warms itself up before charging begins, so it works safely and reliably in winter conditions without any extra effort from you.
Rated IP65, this battery is sealed against dust and water splashes. Its vibration-resistant build handles bumpy trails, uneven terrain, and constant movement making it a solid choice for any outdoor or mobile application.
LiFePO₄ cells deliver over 4 times the cycle life of lead-acid batteries. That means fewer replacements, less money spent over time, and years of steady, dependable power before you ever need to think about an upgrade.
There are no water levels to check, no terminals to clean, and no equalizing charges to schedule. Just install it, connect it, and let it work the HUSKY 2 PWR is completely hands-off from day one.
Despite its high energy output, the HUSKY 2 PWR is designed with a small footprint. It fits neatly into golf carts, camper vans, and utility vehicles where space is limited — without sacrificing a single watt of performance.
BigBattery provides a 12-year warranty policy, ensuring the absence of defects in materials, workmanship, and performance during the warranty period.
