Nzlithium Reviews 

I purchased a 48v 100ah battery to install into a Ryobi RM480e Ride on mower. It was sent very quickly and well packed. Brackets and bolts were provided along with a plug-in gauge. The gauge has a single button that turns it on, and if held in for 5 secs, puts the battery to sleep, conserving stored power. I received the battery in July 2025, but stored it till now and noted there was no voltage drop in that time. I fitted it recently and it was so easy. I have used it and it uses less than 30% to mow 3000sqm of tough lawn. Jesse has always been helpful and responded to my questions.

Excellent support for a high quality product

We bought eight 280AH LiFePo4 cells and a BMS from this company. The BMS would not balance the pack, and often tripped out well before battery capacity was reached. Eventually, the BMS would randomly cut out most mornings, and would not respond to restart commands at all, and we lost a freezer load while we were away. Throughout the debugging process the vendor was rude and unhelpful, telling us all the info was in the manual. When we returned the faulty BMS we were told we would not get our money returned because we had a bad attitude. We were foolish enough to buy another eight cells from him, and after we bought our own BMS there were no more problems. For the cost of him replacing a faulty BMS, it was just not necessary or professional for him to be such a jerk about everything. Add to this, some of his faulty advice cause us a lot of lost time and distress. Up to you whether you deal with the guy, but I'd suggest that you didn't rely on him for any longer term support, unless you were happy to put up with that advice laced with plenty of annoyance.
