I spoke to Lithumax this morning after speaking to someone who gave them the thumbs up ( re races cars)
There will be no problem with the Restart 10 battery (900cca @-20 (equiv to 100amp AGM) .... it's locally designed for pretty well all applications & based around high output cells with a BMS that can handle it .
Drop in replacement for my existing pair of Austral Calcium 650CC/75amp hybrid
As I thought , I would need a second Lithium battery - especially when switching over to both batteries.
They have an option for a 70amp LiFePO4 deep cycle (electribank) which seems pretty good .... it has a high (300amp) discharge capacity so it's clearly well built to handle that .
So if I went with this set up - I would end up with around a usable 115amp cycling & 900 cca (+) for a total of just 13.5kgs Vs 36kgs (75amp) that I currently have with my pair of Calcium hybrids.
Both batteries come with a 3 year warranty.
FYI - The cost of this battery arrangement will be $1724 delivered.
Interesting exercise
