Been hearing from some of our members that have a strong fabrication background, so lets put our heads together to design an enclosure that is safe, and environmentally controlled so we can use the pack in the cold New England weather, as well as the hot south west.
The wish list: feel free to add or suggest modifications to this list.
1. needs to use the relay interconnect board from a standard pack.
2. needs to mount with the same 4 bolts at the stock pack
(drawing of mounting surfaces and their 3D relationships)
3. would be nice if the two computer boards also mounted in the same position as on the stock pack. (drawing of their present location, relitive to the cover and the pack mounting bosses)
4. may need heating system in the colder climates
Determine temperature change response time (thermal mass)
5. may need cooling system in the hot climates
(test cell temperature rise under real world current conditions)
6. BMS for top balancing with charger, Peters has given us a good starting point, but I want to take it further with cell level voltage monitoring and reporting.

as a model.
More good info.
7. I have a design and soon prototype of a 3A booster for the grid chargers. This will work with the GCIM1, GCMI, and the GCO1. Parts will be in hand second week of July.
The design could produce a 30A version with fully adjustable constant current from 0 to 30A at 12 to 250VDC.
8. Battery case wants to protect the cells and have additional electrical safeties in response to an accident
9. stuff We have not though of
10. Stuff we have not thought of before doing the drawings and thermal efforts
