⚡️ Next Restock: Aug 15. ⚡️V2.5 WattCycle 48V 100Ah Bluetooth LiFePO₄ Rack Battery – Active Balancing | LCD | Smart Comms

Nice Unit

Mostly positive evaluation a month in. My biggest gripe so far is the VERY limited range on the bluetooth. It's basically useless unless I'm within 10 feet unobstructed. At that point there's not much purpose in having bluetooth, I might as well use the touch screen. Other than that issue, it performs to spec and expectation.

Great battery.

Very satisfied with the battery performance. Bluetooth connection range (to a late gen iPhone pro) is limited to just ~10feet line of sight.

Purchased 4x 48v server rack batteries and seismic racks.

Purchased 4x 48v server rack batteries. I find the build quality excellent and a great value. I like the features such as seamless communication integration with my Victron cerbo gx mk2 back bone. The touch screen is excellent, the built in battery to battery communication works flawlessly and like the built in recessed terminals and breaker, which give me a better overall feeling of being xtra safe though i still fuse the parallel connections, can't be too safe. I do very much appreciate that they listen to their customers and make improvements. Two things i think would be great to see is the bluetooth range, its very very short. I understand its prob on the bms buried behind the metal case, but maybe provide a spot for an external antenna in the one inside cant be relocated. The other, which is a nice to have would be a cover that went over the entire front of the battery. Yes it would block the screen, but would keep the dogs away from sniffing around the terminals :), i could have gotten an enclosed rack for them, but just dont have the space for that. With that i'd say thanks to team WattCycle for a great products, I've been using your products since late 2024 and haven't been disappointed yet and feel safe using them. Now i need to save up for the hybrid inverter!
