Hi
I wounder if it can e heat problem if I use a old dell server chassi 2U size.
the server chassi will contain 14s40P system
each cell will be around 2300 mah.
I plan to exspand the system also with more battery boxes made from old server chassi
If the heat are no problem

see pic how I plan to build

I'm guessing you are asking if being in the 2u server case if heat would be an issue on the cells?

If so, I doubt it, as long as the charge/discharge is low enough per cell, which would be around 500mA or lower. And even if they did get a little warm, putting some fans to add a little extra air flow would probably take care of that.

They shouldn't get hot. Look at how compact e-bike packs are, and they are for high current applications. Really a good idea for an enclosure I think. However, I would definitely take the opportunity to install some fans. On a hot day, the batteries would appreciate the extra cooling.

Thx for the input. Feels this make it little safer if any cell plan to take fire. The a hole system will not burn.

1. The amount of heat generated is entirely based on your discharge current... issuing a blanket statement that it wont get hot is not correct.

2. If a cell does catch on fire, it will most likely cascade to the rest of them.

3. It should be very easy to provision some fans into the system

4. Chassis is conductive top and bottom, non conductive insulation would most likely be required.
