Mowing test

 I finally got the charger in, I wired a plug and tested. I had already charged the batteries in sections so the new charger didn’t charge long and shut off. 

I wanted to do a mowing test even though I didn’t have all the batteries I wanted to install. 

I found the current decreased as time passed, perhaps the grease in spindles became softened with heat.

I mowed for about 40 minutes, probably a bit more than 1 acre. Power use was 78 amps,  about 3850 watts. This tells me my batteries have about 80% capacity at full charge.

I estimate having enough for the entire yard if I add the other batteries. I did note the motor gets pretty warm, can’t leave your hand on it. The spacer to keep batteries away from motor inlet was narrowed, it may help. I may add a fan later.
