As a professional fire protection engineer (but not involved in end-user product development whatsoever), I can tell you that protection of stored and in-use lithium-ion and similar types of batteries is currently a very hot topic (pun intended). The phenomenon of thermal runaway poses new and

In a deep cycle application such as providing backup power to systems after a charging system failure, A good LiFePO4 battery will provide much longer service at a steady voltage than any lead-acid chemistry and at about of the 50% weight per AH and for about quadruple the discharge cycles. There i

Jeff thank you this has long been my position. The steady state delivery after a dynamo goes down also biases me to SLA... https://youtu.be/FPBaAil4dNg?feature=shared On Thu, Jun 13, 2024, 4:53 PM Jeff York via KRnet wrote: > I spent years as an engineer in Industrial Lithium Ion technology. Mo
