As encouraging as it is to know that LFP batteries are safer than most other lithium-ion types, overcharging, damage and abuse can still cause problems, primarily an inability to hold a charge. Lead-acid and lithium-ion are two entirely different technologies, with different discharge characteristics and charging requirements. As such, it’s important to approach LFP with an open mind and read the FAQ section of manufacturers’ websites to learn about these batteries’ unique—and, for the most part, limited—requirements. Lead-acid batteries are fairly inefficient but also tolerant of abuse. Lithium-ion batteries are highly efficient but susceptible to damage if overcharged or allowed to drain below a certain voltage threshold, usually in the 12V range. Vibration and shock can damage a lithium-ion battery’s internal connections, which is why manufacturers now offer their batteries in OE-sized cases. Batteries that are smaller than a bike’s battery box should be shimmed with foam pads to prevent shock due to unimpeded movement.
