Re: (ET) Lithium battery deal

[Dean Stuckmann <dstuckmann icloud com>]

Hi,
I’ve used my ETs since 1980 and have always used good old lead acid with 
the on board chargers. I know nothing about this battery tech and hope you 
folks can answer some questions.

- Performance wise, since 4 sounds like the max, how would they stack up 
to (6) lead acid 235AH GC125s?
- Would there be issues with the on board charger or batteries because of 
the BMS? I’m not actually sure what the BMS does to tell the truth.
- I’m a bit confused with the size specs. The description states 13" x 
6.5" x 9” while the dimensions in the spec sheet shows 21” x 12” x 17”. 
Bottom line is do 4 fit in the battery box or not?

Thank you all!

Regards,
