Mow 1 acre 3 times vs less than once on 5 yr old? lead acid batteries I got from Harold.  I don't recall the amp hours.
 
For inrush - a guy on the FB page sells a slow start device although I am not using it on my install.
 
The state of the art in batteries and chargers has increased so much in the last 3-5 yrs its really amazing.  And they cost less than lead acid batteries.  I paid $800 for the battery, charger, shunt and controller kit on Amazon.   Literally hundreds of youtube videos on these topics.

Thanks for the feedback.  How does the mowing 3 times compare with the old set up?  What was the amp hours on the old set up?
 
One comment on converting.  I think it is important that the new batteries can support high inrush needed to start the mower or snow blower.

Hi Larry,

On the Ryobi facebook page DC house and Chins batteries are used about 50/50.  I went with Chins 48V 100 Amp hour battery with the matching charger and controller and bluetooth BMS with individual cell balancing that you can monitor on your cell phone.  This technology is so much better than the dumb brute force charger on the lead acid batteries with no cell balancing on the 55 yr old ETs.

I can mow my lawn 3 times without recharging.  I cant speak to long term reliability yet, but the charging and battery balancing are so much better it should do wonders for battery life.  I would never buy lead acid batteries again.

When my ET needs batteries - I will convert to Lithium.  I use my Ryobi Zero Turn for grass cutting (far superion) and my ET for everything else.

Jeff
