    I have already very same style battery, just had own wiring, plywood plates and bottom plate. What I can recommend is to use plastic pipes over threaded rod in case of physical impact and possible shortcut between cells (bare thread works like a saw!). And one question, what torque do you use on your rods? In my opinion have to be very, very low (I use 4xM10 rods and torque @ 1.5Nm) - but Jehu have done way more batteries than I ever seen :)

    @jehugarcia hi Jehu, thank you for you recommendation on the BMS, about to install a system in a camper that will be used daily. What inverter do you recommend if I want to a pure sine wave, 240 volt and higher watt (around 3000) output. I know Victron is great and would like to use though can you suggest a lower cost brand, I am okay with using an imported model, hoping you have experience with a brand that consistently makes clean power at the advertised specs?

    Problem with daly BMS in general is the poor balancing. (Only 100mA, and passive, not active). There are other BMS out there with active 2A balancing.... with proven quality and about the same price.

    • @martinmooren9536
      @martinmooren9536 2 วันที่ผ่านมา +2

      Poor balancing, slow update values in the app, measured amps bounce up&down like crazy with a constant load. Therefore the shown power is not correct and the battery percentage is wrong.
      I still use two Daly's but bought two cheaper JK's for my 3th and 4th battery. Battery percentage is still not perfect but the rest is. I wouldn't buy a Daly again.

      @@s.mendez7160 I have a 90kWh battery bank consisting of 9 banks of 200Ah-16cel (10kWh). After a LOT of research I came up with the JK inverter BMS. As said here by others, the battery percentage goes off when you don't hit the 100% SOC from time to time. Right now in winter here in Belgium (where i live) I never get 100% soc when only relying on solar. So every 4-6 weeks I set my victron inverter grid setpoint tot 1kW. That way after a week the battery hits 100% again, starts to (active!) balance and off we go. Note: english is not my first language...

    Please don't attempt to save just a couple hundred bucks (thousands? no way!) with a DIY battery. You need skills and proper equipment. That thing shown in the video is 14kWh, a lot of energy! The connecting PCB seems it doesn't take into account for expansion and contraction of the cells, which still happens despite the compression. The BMS main contacts are close to bare metal panel with no insulation whatsoever. just need a screwdriver in the wrong place to make a huge mess.
