I also stood on the board with i3 module and the first thing immediately that I noticed is how much pendulum effect it added, being a very heavy mass high up.
I also bought it as an investment, as it can be a good energy storage system for possible solar systems, UPS and works/mates well with 48V solar inverters.
The reason why I also decided to go with the trailer route, is that I foresaw that adding too much weight on top of the board was gonna cause stability issues. I can optimize the height of the battery in the trailer to be low, so it’s not top heavy.
Yeah fuck having that on the board. Keep it low in a trailer and you can keep your supplies/camping shit on top. Trailer is perfect for this and exactly what i will do when the time comes
HOLY COW. Your battery pack is gigantic. GIGANTIC. Your battery pack is literally the biggest thing within the tri-state area. Your battery pack is bigger than a small elephant. It is bigger than, like, a tree. A big ol’ tree. Probably a coniferous. Lots of branches on your battery pack. You must wake up every morning and thank the good lord above. You are truly blessed. Congrats.
Here’s an early concept design for the aluminium frame for the trailer with the roughly correct size of the module in the bottom.
I disassembled the positive terminal plastic housing, as I need to get to both B- and B+ to charge and discharge, as I want to do a capacity test, which is gonna take quite a while with a 150W load
Also, when people complain about slow balance currents. This sucker has 56Ohm bleed resistors, where the FlexiBMS is using 47Ohms, so technically this is a slower balancer than the FlexiBMS, but it doesn’t have the same size constraints as the Lite does.
I’ll 3d-print a custom holder for the balance breakout board and probably integrate the FlexiBMS on top of it as well into the same enclosure. It’ll be a nice contained package then.
EDIT: Still need to get to that negative terminal, but I don’t see any easy way to get rid of the enclosure around it… might have to go a bit more destructive on it.
