I Have a friend who has a business in gardening and will soon want me to convert him a ride on lawn mower to electric,
I have a good idea on how he wants it to be done,
Light, easy to charge, monitor battery easily, no balancing charger, bms , ect. But a small light machine that can be moved around easily... ill try and reduce as much weight as i can
Motor, im thinking of using the hpm5000b , i like it because i use it on my ebike, plenty of beef i think.
Controller, prob use a kelly, thinking max 5kw to keep the motor cool, dont want it to chew through the battery, but i want it to be more powerfull than any ICE lawn mower haha
Batteries im going to use a Fully functional bms from founding power. Use it with the lcd so i do not require a cycle analyst for this build.
Lipo 20s and id say it will have to be 24 ah plus using 8000mah zipp 5s bricks
Now I will need to do some research and find out how these lawn mowers work, so i can attach the motor correctly and get it to run like the old one.
We don't have a ride on lawn mower yet but i will look when i know which type i need so it will be an easy conversion.
