I did as you did. I left the center braces and old tie down tabs in place. I used 1/2" HDPE for the platform and bolted it down to the perimeter tray angle iron. I am not sure what you meant by "side plates." There is a small tray on the driver side outside the battery tray. I have a plastic box there now to store the pack and aux batt chargers. Something else I did was to remove the old charger port in the seat and replace it with one of these. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
It covers the old hole perfectly. It is mounted to a plastic outlet box on the inside. I riveted another plastic out box to it back to back and put in a 115v duplex outlet. So now I just plug in a regular extension cord to the outside plug and have two outlets inside for my chargers. The male outlet is deeper than the box so I drilled a 2" holes in the back of each of the outlet boxes which makes wiring to the outlet simple.

I go in the mud a lot and I thought that they would just fill up especially on the right side where the plate is upside down.

I lag bolted a couple of 2x6's across the battery tray from the bottom and then the floor is screwed down to those to secure it in place.

Could you talk about what went into assembling the pack? All over EV battery centers website it talks about this is a DIY kit, you have to assemble etc..... Could someone with average knowledge do this without electrocuting them self. Im ready to pull the trigger on the 52v, 3200Wh DIY pack but im hesitant because I cant find any info on assembling the pack and such.

I'm going to try and post a couple pdf's that Nick from EV Batteries sent me and then my comments may make more sense. Stand By

Take a look at these

I thought most of the guys here were buying pre assembled packs?

Customers have told me they received packs with an SB50 plug, ready to plug in and go

Sb50? That is a little inadequate for the power that runs through it. Sb50 is also only made to accept 8g wire.

Just got and assembled mine yesterday. Not a lot of detail in the assembly pdf's that they sent- they assume that you know positive goes to negative when mounting the bus bar (you should, but as a diy kit this should be expressed) Doesn't include some stuff like crimp connectors to wire up the BMS. Wiring diagram is a little unclear too.
This is the 7 cell DIY kit 58.8v 60ah kit. 32kwh. Saves about $250 as opposed to buying assembled.

You need to go to the EVbatterycenter website and check out the specs. The assembled ones come with a 50amp charger plug and a 175amp power output plug.

Here is how small the little pack is. Red plug is the SB 175 Anderson and at the base of it is a grey SB 50 Anderson.

The charger I ordered from EV Batteries came with the SB50 but I did not use it since I had already installed Anderson 45a plugs when I installed the Quick charger I originally had.

I thought the pdf that Nick sent me and I posted here earlier was very clear on the proper order to place the packs and where the bus bars went, my kit also came with all the ends I needed to wire the harness for the BMS except in my case with the 14 modules the last few wires were to short so I just soldered on wires that were cut off from the first few connections, this worked out just fine. Since the bus bars seemed a little light to me I ordered an extra set and doubled them up. The little bus bars for connecting the center taps would not line up with the bolt holes so I used a paper punch to fix the holes and they were a lot cleaner than the original holes.
