    RV DIY battery box: plywood vs acrylic vs FR4 vs something else?

    Yes, you are right. The cost is in the shipping. If you were to by 1 box it would cost you almost $100 total for the box to get it to your door. I had to buy 30 boxes to be able to match the price on aliexpress and alibaba. Alibaba is a little cheaper than ali but not buy much.

    You could get just as creative with one of these boxes. Some like plywood, some like plastic and some just want something simple. I have some of these boxes if interested.

    I agree with what your saying. I was just stating that cycle life has nothing to do with calender life. The average Callender life of lfp is 10 years. Yes there are the cases of just a bad cell that prematurely fails.

    I laughe at people who convert cycle life to calendar life. Cycle life has nothing to do with calendar life, its strictly cycles. All lfp holds the same Callender life. Regardless of cycles.

    That's actually not a bad capacity from batteries bought from aliexpress. You should feel lucky. Your not going to get any kind of refund from them, aliexpress allways sides with the seller. Or they will have you send them back and once received they will send you a replacement. The price of...
