Duel Use of Lithiums in Cart and Boat
With the emerging lithium market of drop in replacement for lead acid, I'm researching the possibility of having a set of 4- 12 volt 100AH lithium batteries serve both my 48 volt DS cart and my fishing boat. I use the cart and boat at different times of the year so moving the pack would not be an issue. My DS cart has an OBC so that would be by-passed and I would purchase a 4-bank lithium charger that charges each battery separately. These batteries have their own BMS. The one concern I have is determining the max amp draw of my MOT-A4 motor. I seldom use more than half throttle on the cart and typically cruise around 10mph on trails.
Thoughts? |

What controller do you have in your cart?
If the motor is capable of drawing 9,000,000 amps but the controller can only draw 200 amps then your max draw is 200 amps. |

Lowering the throttle rate will also reduce the motor current demand during acceleration as it prevents the motor from getting too deep into its inefficient region.

The higher capacity Trillium, 92AH and 110AH can deliver 250 amps only for 30 seconds at a 77F temperature, much less when they get hotter.

Sergio, you are correct. The data sheet I have was from Oct 2018. Trojan has updated the Trillium specs on their website. Thanks!
