Absolutely not.
First of all, the charging cut-off voltage is different. The charging cut-off voltage of lithium battery is 4.2V, while the charging cut-off voltage of nickel-metal hydride battery is 1.5V.
Secondly, you You'd say three strings of nickel-metal hydride batteries are enough. The charging cut-off voltage of three strings of nickel-metal hydride batteries is 4.5 V. It seems feasible, but in fact. this is not feasible. Experiments have proven this, because the single-cell lithium battery charger is not designed to charge three strings of nickel-metal hydride batteries and does not have a parallel charging function. This will cause the voltages of all three batteries to increase. to be different. The voltage of the two batteries near the positive and negative electrodes will be higher, and the voltage of the battery in the middle will be a little lower, which will overcharge both batteries close to positive. and negative poles, damaging the battery, and the battery in the middle will not be fully charged. When using this three-string nickel-metal hydride battery, the battery close to the positive and negative poles will be greatly increased. discharged, which is not conducive to extending battery life.
Finally, the method of charging nickel-metal hydride batteries is very complicated, much more complicated than that of lithium batteries. Good nickel metal hydride chargers typically use pulse charging, which helps improve the lifespan of nickel batteries. Of course, most domestic counterfeits now use a transformer + rectifier bridge. If you use this type of charger to charge nickel batteries, the battery will definitely die before long.
