Plug and play

I recently purchased a second of these batteries to augment my existing battery storage. I was expecting some degree of difficulty in paralleling them; however, there was none! It just plugged in and worked! Total setup was about 5 minutes. I wish everything was as easy. I bought the first battery 6 months prior and this new model had many updates- it’s great to see that EG4 is always improving their products

EG4 PowerPro WallMount AllWeather Lithium Battery

Installing this battery is seamless with 2 EG4 18K. It worked right out of the box did not require a software update. You can never have enough battery, especially if you have an EV.
