My e-mowers have been corded type, so no battery problems. However, the replacement motor I put in the B&D was a 36 volt and I ran it from a 10ah PIng lithium battery that I carried in a backpack, which made the mower much more maneuverable.
I ran it that way for 4 seasons, until the motor packed it in from bearing play that I carelessly didn't recognize until the armature demolished the magnets. I think e-mowers in genearal are probably hard on batteries, because they present large loads on batteries kept small so the mower doesn't get too heavy or expensive. With my B&D 36v, the idle motor load - just spinning the blade in open air, no cutting - was IMO obscenely high, 8+ amps. I wasn't able to consistently read the ammeter when cutting, but I had a 20a breaker on the battery, and it tripped now and again in very heavy grass and when I hit roots. The battery is LiFePO4, not LiCo. I don't know whether that makes a difference in a situation like this, but it held up through the 4 seasons I used the mower, even though the load was higher than Ping advises (they like to stay at or below 1C).
