Campervan DIY battery build HUGE POWER!

Lithium Titanate Oxide battery build
Around 9.5kWh capacity LTO chemistry

The battery pack was designed so I could have started off with 55cells (5kWh) and later expand it by slotting in upto an extra 44 cells at a later date (when I had more coin), I managed to come up with the coin for a full pack for the build.
Batteries seem solid, although I have seen occasional reports of these batteries venting online. I'm not sure if it was from abuse or design/manufacturing flaw. Will keep you updated with performance of these.

*** am thinking about doing a group buy from a bulk distributor to get the cells at a discounted rate - let me know if interested***

(Update 28/10/20: I have had problems contacting a supplier that I purchased my batteries from. I managed to get hold of them today. The person I dealt with had left so my emails were going nowhere. If you are interested in a group buy for significant discount get in touch brendonsbuilds@gmail.com I will be going through the details of this with the supplier this week and will be in touch).

Aliexpress affiliate link for cells. Please let me know if you have any issues with supplier.

Part files: goes without saying... this is not a proven or tested battery pack design, little care, no responsibility.
BUSBAR as tested and shown in video made from 4.5mm thick ali machined - but could be laser cut. Clearances are tight so may have to be opened up if laser cut.

BUSBAR - slotted from either side, not built or tested. It has slots from either side so that any cell could be changed without having to pull the pack apart:

BUSBAR brackets, I machined these from Nylon - tho they could be printed (not recommended) have to be aware of creep in plastic on mounting points etc. All cutters are intended to have a 0.5mm corner radius on them to reduce the chance of splitting over time. This design is slightly modified from the video to make the brackets more rugged.
