36V 50Ah Lithium Battery Pack for Solar Energy Storage with Bluetooth APP Monitoring

We've had a few solar storage integrators ordering these for off-grid cabin setups where teh owner wants to monitor SOC remotely via their phone, and the Bluetooth app basically makes that painless — no need to wire up separate display panels or run comms cables through walls.

On the spec front, it's 36V nominal, 50Ah rating giving you 1800Wh total, with a max continuous discharge of 50A and a 100A peak for ten seconds if a motor or inverter draws hard briefly, which matters for starting loads on a golf cart or a marine trolling motor.

The charge voltage is 42V and the discharge cut-off sits at 30V, so you're working with a 12S configuration of LiFePO4 cells that cycle over 2000 times at 80% depth of discharge — typically lasts about eight to ten years in daily solar cycling, give or take.

We usually have these in stock for smaller orders up to 50 units or so, but for bulk MOQs above 100 pieces we need to check cell availability because the BMS variants differ depending on whether you need Canbus, I2C Bus, RS232, RS485, or just Bluetooth — Bluetooth board adds about two weeks to lead time.

Most buyers ask about the weight first — it's roughly 15kg for the standdard config, which is lighter than lead-acid but still hefty enough that you'll want the mounting bracket we include; also, the dimensoins are customizable if you're fitting it into an existing battery tray, but confirm the profile when you order.

It's not ideal for high-rate pulse applicaion like a winch or a power tool — the 50A continuous limit means you'd trip the BMS on over-current pretty fast, so stick to storage and moderate load scenarios where that 50A rating actually covers peak draw comfortably.
