OK Guys
I am looking for the required/mandatory spec's to have my battery built,
so I can compare costs etc, for these 2 battery builders, UPP and EM3 EV.
Some of the questions I have are this:
Which of the below spec's are REQUIRED for a good battery build.
(I know nothing about building a battery, or what is required.)
80? cells, 21700 cells equal to 2 - OEM battery's,
( MY OEM LG 21700 battery has 39 cells/13 in series, 3 in parallel, 15ah/720wh x 2 battery's.)
48 or 52V with a quality 30/40/50A BMS? (OEM is 30A)
Quality of the BMS?
Advanced BMS System?
Balance BMS?
Intelligent Dual Battery Balancing Module?
Case/construction methods ? A triangle case with these maximum dimensions =
431mm x 457mm x177mm x 88mm thick/wide. Hard or soft shell construction?
Proper cell connections/ What type?
Is there any cell protection fusing?
Cell separation type?
Temperature monitoring?
Pure Nickel/Brass/Copper connectors ?
What else should I ask about/for?
Your thoughts and suggestion...
Thank you,
Don
