Pre-Programmed BMS

The included BMS ships configured for your cell count and chemistry. No laptop, no parameter guesswork.

Save vs Pre-Built

Building your own pack costs significantly less per kWh than a finished battery -- with the same Grade A cells.

Everything Went Well — Ordered Two More After Testing

I purchased a 16kWh DIY battery kit with EVE 314Ah cells. I originally planned to use my own freight forwarder, but after comparing the options, I decided to use Anna's shipping service. Everything went smoothly overall. There was some delay because the shipment was inspected by Chinese customs, but fortunately I wasn't in a hurry to start the project, so the extra waiting time wasn't a big problem. After testing the first system, I decided to order two more of the same setup. I'm also planning to recommend it to neighbors and friends in my community so we can order together and save on shipping costs.
