电动工具更换锂电池问题

如题，电动锯子LPS7000原来电池用A123锂铁的，但日久及容量（约1000mAh）限制，很不经用。拆开马达是6Ⅴ的，想更换成SONY VTC5动力电，2600mAh 35A，但电压2S会是8.4V，原线路板及马达，长时间工作，会不会高压烧机？

A123全网最高只有1100mAh左右，容量实在太小了。

要不加个降压模块？https://app.rcfans.com/public/emotion/face_007.png

可以有，这东西改造空间几乎没有，需要大安倍，放不下https://app.rcfans.com/public/emotion/face_004.png

放心上，最大2s妥妥的

锂铁2S满电是7.2Ⅴ，ⅤT5串联2S充满是8.4Ⅴ，电压差1.2Ⅴ。试用了，劲爆好多，马达端直接就是电池电压。

改无刷？！https://app.rcfans.com/public/emotion/face_018.png当然好

改，改，改，组好了！强劲好多，顺便也把2S充电口也加上，效果不错，大家可以参考。
