Re: (ET) dchpower

Yeah, but we WANT to use the 55 year old charger on the Elec-Trak. History and all :-)
From the specs, it looks like the battery wants a 43 volt charge which should be the taper voltage of an E20. Only odd thing is they say you can't put the batteries in parallel, not sure why?

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!
