Looking to shave weight and this seems to be the best price vs. weight vs. CCA lithium battery option on the market.
Boat will only be powering a
- Bosh Fuel Pump
- Trim pump
- Jack plate pump (in the future, maybe if needed)
No radio, no lights.. pretty basic
Cranking amps: 625
Voltage: 12v
Standard: 6.5
Max: 25
Size: 166x124x175
Polarity: - +
Weight: 5.5lbs
Is 625 CA enough for a Merc 2.5 200xs ROS engine?
This is what I'd use

my Opti manual says 800 CCA.Quote:

we rig all opti's with 1000 cca
Won't fire w less than 1000cca it will turn over and u will think there's a problem but no start
I run Odyssey PC 680 with my twin 200XS engines with no problems. Since its twin engine I always figured I could use both batteries to start one engine if needed. Never needed to do that yet.
Not trying to defy what others are saying. Just saying what I'm using and is working.
I use an Optima 720 cca and never had a lick of trouble.

I can start a motor with 250 lbs of compression over and over again with the 24 cell Antigravity. I feel pretty certain of will start an Opti
Battery cable size plays a big role as well.... I never go smaller than 2 ga in any rig...... 4 ga will work, but eventually corrosion will make it's way in so having the extra cable size helps.............
