From the perspective of public safety, lead-acid is better and suitable for different groups of people, so there is no need to worry too much. Even if there is a problem with the battery and charger, it is just the battery bulge that is hot. Lithium batteries are different, they are naturally delicate and violent. If you don't wait well, you can explode at any time, and you can't control it at all. If you have seen the explosion scene, you will know it. A special charger is needed, and it cannot be taken wrong; you need to pay attention to the charging problem and not overcharge. It is not like lead-acid, which can swallow your breath and suffocate internal injuries. If the lithium battery breaks out, there is no regret.
maintenance
Lead acid is simple, generally
4/5/6 batteries are connected in series, just twist a few screws and you can see them when you take off the seat bag, which is convenient for maintenance. The battery is broken and the line is broken on the road. Any car repair shop can fix it, and it doesn't cost much money. The voltage of lithium battery is low, the voltage of ternary lithium battery is 3.7v, the upper limit voltage is 4.2v, the lead-acid battery is 60v, and the full charge is 65v. If it is a lithium battery, it needs 65÷4.2=15.48, and 16 strings or 17 strings are also possible. Moreover, it is necessary to increase the capacity in parallel, so it is definitely not easy to maintain so many battery packs together. Lithium batteries have to go through layers of protective packaging, which cannot be solved by untrained repairmen. Lithium battery-related equipment is also required. Many repair shops do not have such adjustments. Just pray that there is a problem elsewhere on the road if you use a lithium battery, otherwise... push the cart... just wait for support
In terms of price
Well, generally using lithium batteries is not bad, but most people still find it expensive. Lead acid is recyclable, high value, a set
60v20ah trade-in is currently as low as 350 yuan. According to the current usage of the battery, after 2 years of use, it can be used for another two years after spending three or four hundred. The recyclable value of lithium battery is not high. Logically speaking, the lithium battery can be used for at least 4-5 years, and the lead-acid is replaced every two years. You have to replace it twice, which costs 700/800 yuan. This cost is something you need to consider. It does not include maintenance costs. The problem is that there are many brands of lithium batteries on the market, and the quality is uneven. Can it really be guaranteed for 5 years? Maybe it will hang up in two or three years, and the cost is worthless.
