我有两个12v的电瓶,一个是36A的一个是45A的,两个可以并联起来用吗?我是用来做太阳能板的蓄电

我有两个12v的电瓶,一个是36A的一个是45A的,两个可以并联起来用吗?我是用来做太阳能板的蓄电池组,求详细解答~~~

如果两个电池都比较新,应该是没有问题的,有人专门做过相关实验,无论是充放电都没有什么影响。因为两块电池的电压相同,从安时数上来看也相差不大,放点时45Ah的放电多些,36A放电少些,但二者的放电时间是差不多的。
如果电池一新一旧,旧电池的内阻很大,新电池还要给旧电池充电,可能总容量也没增长多少。追问

两个都是旧电池,那如果我在45A电瓶正极接一个防回流二极管,45A电瓶里的电就只能充进去不能流出来,那它就不能给36A电瓶充电,这样并联起来可以吗

追答

看起来是可行的,具体试一下吧。
你可以两块电池上都加一个二极管,但注意二极管的电流要足够。

用两个控制器,电瓶输出+极加二极管再并起来做输出(防反流)
