“I look forward to continued success in my relationship with Lithionics, as I have mentioned many times in my videos; I wouldn’t ever consider any other battery!”

“You know I must tell you that it is always such a pleasure working with you. I totally appreciate that you treat all my projects with respect and promptness – even though Pinnacle is most likely one of the smaller fish Lithionics deals with. It is absolutely wonderful to have such a reliable and professional person to deal with whom is also excellent at communicating!” “Phil is actually both my Hero and a real Superstar! … I think that I can also say that I can extend the same sentiments to just about everyone that I’ve ever dealt with at Lithionics – right from Reception to Shipping employees! I also believe its equally (if not more) important to let people know when they are doing a great job. Too many people are only too quick just to criticize….”

We really like the Lithionics Battery Management system (BMS) as it offers some protection from over charging, under charging and provides two isolated channels to the batteries. They also have a dedicated FCC circuit that connects from the BMS to our Alternator controllers which can shut them down in case of overcharging without damaging the diodes.
