Re: (ET) dchpower



Driving the Elec-trak in insane mode (blowing snow uphill at full speed) I didn't go much above 300a total draw.

  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.

Does anyone have experience with these LiFePo batteries and charger?

A friend has just installed the 48v version in his Ryobi electric 
zero-turn.

Thanks!
