![]() ![]() This comparison is not a comprehensive list of advantages and disadvantages of lithium-ion batteries vs. The advantage goes to lithium-ion batteries! Compare that to a lead-acid battery that needs the water checked and topped off and the battery connections cleaned monthly. Clean connections and a visual inspection are the only maintenance required. Lithium-ion battery maintenance only requires keeping them clean, particularly around the battery terminal connections. A golf cart or battery professional with experience in lithium-ion batteries will be able to diagnose the battery issue. Battery packs that are bulging, getting extremely hot while charging, or venting anything from the battery case should be taken out of service and inspected immediately. There are still visual signs you should watch for, however. This system protects the battery pack by monitoring battery temperature, voltage, and many more parameters set by the battery manufacturer. Lithium-ion batteries use an internal Battery Management System (BMS). Overall, lithium-ion batteries are extremely safe. Lithium-ion golf cart batteries have a cycle life of 2000-5000 cycles and require ZERO maintenance! Lithium-ion Safety Lead-acid golf cart batteries typically have a cycle life of 500-1000 depending on charging habits, maintenance, and use. Cycle life refers to the number of times a battery can be discharged and recharged before it needs replacing. This leads us to the next performance advantage, cycle life. The same 48 volt, 165 amp hour battery pack in lithium-ion will give you 132 amp hours of useable energy. Lithium-ion batteries have an 80% depth of discharge. For example, a 48 volt 165 amp hour battery pack has 82.5 amp hours of usable energy before performance and battery life is reduced. Lead-acid batteries perform better and last longer when the batteries remain above 50% depth of discharge. The performance advantage that comes from lithium-ion batteries is due to two factors. Lithium-ion batteries have a 7-10 year design life! Better Overall Performance Golf cart owners can expect to replace their standard lead-acid golf cart batteries every 3-5 years (depending on maintenance and use). Standard lead-acid golf cart batteries weigh 65-70 lbs EACH, and you will typically need six of them for a whopping 390-420 lbs! Long Life Depending on the manufacturer and configuration, a lithium-ion battery pack will weigh roughly 90-100 lbs. The most noticeable is the weight differential. Lithium-ion batteries offer many advantages over a standard flooded golf cart battery. Benefits Of Lithium-Ion Golf Cart Batteries Light Weight This article will highlight some of the benefits, safety, and maintenance required when using lithium batteries in your golf cart. When it's time to replace the batteries in your golf cart, you might want to consider lithium-ion batteries. ![]()
