Works flawlessly with my EarthX batteries. A serious charger for the new world of Li batteries. Very robust, you get what you pay for. I would recommend to people I know but I'm the only one with the lithium batteries.

Good kit works great

Higher current charger enables me to reuse this for any other sized batteries I may have. BMS reset feature looks handy but have not had a chance to use it. Case seems really sturdy compared to other trickle charges I have, but they are rated 1 Amp and below...

Very nice charger but it is pricey compared to other models. That being said I love the quality of Optimate chargers and have several and they have all been reliable and helpful.

Very nice system. Recommended for EarthX batteries. Instructions could be a little clearer. The thing I like is you can permanent leads that can be installed on the battery. This allows you to manage the battery from a location without direct access to the battery.
