Pecron EP3800-48V Features
You get 3,840Wh of extra power to last way longer
This battery adds a massive 3,840 watt-hours to your existing PECRON system. That means your fridge, lights, and devices keep running far longer before you ever need to think about recharging again.
LiFePO4 chemistry keeps your battery safe and steady
LFP batteries run cooler and more stably than regular lithium batteries. This means less risk of overheating, more usable power on every charge, and a safer option to keep inside your home, RV, or cabin.
It lasts over 3,500 cycles so you won't replace it soon
This battery holds 80% of its capacity after 3,500 charge cycles. Used daily, that's nearly a decade of strong performance. You save money long-term by not replacing it as often as cheaper battery options.
Plugging it in is simple thanks to the MJ32 cascade port
No complicated wiring or technical setup needed. Just connect via the two MJ32 battery ports and the included cascade cable. It links cleanly to your compatible PECRON station in just a few easy steps.
It works reliably across most everyday temperatures you'll face
Rated for use between 32°F and 113°F, this battery handles most real-world environments with ease. Whether you're camping in summer heat or riding out a winter storm at home, it keeps performing without issues.
The compact size makes it easy to store almost anywhere
At just 17.3 × 12.2 × 8.8 inches, it fits neatly in an RV bay, garage corner, or cabin shelf. Despite holding nearly 4,000Wh of energy, it takes up surprisingly little space wherever you need it.
It works with five trusted PECRON power stations right out of the box
The EP3800-48V is confirmed compatible with the E1000LFP, E1500LFP, E2400LFP, E3600LFP, and F3000LFP. If you own one of these units, adding this expansion battery is a confident, worry-free upgrade to your existing setup.
