Customer Feedback from an RV Conversion Shop
Purchased four of these units for our Class A Motorhome to replace AGM batteries. They were packaged well with heavy cardboard and foam caps top and bottom. When charging up each unit individually before install, they all started at 13.16V and accepted nearly the same Amp Hours (~143 each). Performance has been great so far to charge/discharge, minimal temp rise when doing so at the 60 amp suggested limit each too. Included cables are a bit small for batteries of this capacity (25 mm^2) but good for balancing if you plan on putting in series. The BMS also doesn’t stop low temperature (32F) charging so be mindful to install an independent method to stop charging or keep them above with a proper thermostat controlled heat pad. Will update review if any issues come up.
Testimonial from our partner’s customer
Used this in my new Forest River Epro 19FD travel trailer. Fit the stock box excellently, all the other lifepo4 batteries were too wide. I made up a simple locking system using scrap items of metal. Battery works well. The battery it is compared to in the picture was a 100ah sealed lead acid AGM battery. The new Lossigy is a 200ah battery. Lasts way longer, can drain it down way further. Bought a 55a charger to restore it quickly by inverter-generator.

Holds backup power for a very long time. It works perfectly in a bomb shelter in Ukraine.
