1 starThis is the worst company I have had the displeasure to deal with. They are arrogant, indifferent and will NOT deal with the issues with their product. I have two batteries for my solar system. They have had problems since the beginning, One I have sent back already and it was supposedly repaired. I had to put the thing on a pallet, send a picture, buy foam and a box to cover it, send pictures, buy straps and strap it. *************. Now the batteries will not make it through 6 hours of use without having to pull from the grid. This fly by night company now wants me to send back both batteries and have nothing while they decide if there is a problem with them. No time frame for how long they need them. Just do what they say and send more pictures.Review fromJustin T

5 starsBeen a great experience so far with my 30.7kWh system! Unsure what all the negativity is about, maybe they recently upgraded their teams and company because I had an amazing experience!Review fromAndrew D

1 starPurchased 2 Husky2 48v batteries from Big Battery on 9/13, shipping was very very slow (no communication). Batteries arrived and the advertised CAN/RS485 communication doesnt exist. Big battery claims i misunderstood how this communication works (ie its only for their power meter and not to connect to inverters). The manual has a conneciton diagram for it to connect to inverters and the manufacture of the battery (Big Battery resells it) is Voltgo Elite. They also specifically state [Reliable BMS] Our intelligent BMS (battery management system) provides always-on short-circuit and over/under voltage prevention, as well as temperature monitoring. "The battery can communicate with Victron, Growatt, Schnelder, Inhenergy and luxpower inverters by RS485. And it also can communicate with Growatt, Sol-Ark, Deye, Megarevo, Victron, Luxpower, SMA, Inhenergy, Solls, Afore and ****** inverters by CAN." CAN/RS485 is explicitly used for closed loop comminicaiton and battery monitoring. Big Battery has stated they will charge us a return and shipping fee to return the batteries despite being incorrectly advertised.Review fromStanley M

Warranty is a scam. Battery lasted just over a year and was getting technical support. As soon as it was determined the battery would need to be replaced under warranty I have been getting the run around. Its been almost two months and I cant even get a response without sending multiple emails. The responses dont add up to much anyway it seems like they are just hoping I will give up. Do yourself a favor and look elsewhere for your battery needs.BigBattery Inc

Hello ****, I'm sorry you're having technical trouble. I searched the number attached to order SO005622 and cannot find any calls from you. We also lack emails with you. I found a live chat from March 2024 in which we requested your installer/tech be present on a call with us and the chat ended shortly after. Feel free to call within our operational hours of 8:30 am - 5:00 pm PST and our team will gladly help you. We can also be reached at ********************************** or the same live chat on our website. Let us work together to get your issue resolved.Review frombranko s

BIGBATTERY does'nt honor their products, demands an order number for a battery installed by the dealer 2 years ago. They have all the information they need on their stickers. 10 year warranty on the battery and it didn't last 2 years then they give you the run around. Stay away. If I cant get it resolved in the next week it goes in the trash and I'm buying another brand from a reputable company. $5000 of c*** and bad ****** learned about this company.BigBattery Inc

1 starThis company is working on a shoestring budget. Zero support, zero investment in their employees. Very disappointing to work for. Employees need to finfmd their own leads, use their own cell phones and laptops.Review fromMt T

1 starDo not trust this company. they lied to me about my battery being repaired the second time it shipped off. it first went in for over heating. when i got it back , the heating issue was fixed however. my amp hrs were down -20 and would not charge over 57v. they clamed they fixed the battery and lied to me. the guy continued to blow smoke. I am very upset with the quality control and professionalism. the battery specs are suppose to be 58.8v *** charge, 150a continuous. they denied my warranty blaming this on me, after 2 fuses had blown already. i had nothing to do with this faulty battery. If i would have listened to my gut i would have never spent the 7000 dollars on there equipment in which never performed like they said it would.
