  5. Help from OBN...Battery Pack BMS

    @OBN Great work on building those batteries. Wish I had taken a course years ago. Do most of your supplies come from battery space/AA Portable Power Corp? Does the precision double pulse welder work better than a high quality Hakko soldering unit? I'm going to try my first 4S 14.8V Li-ion...

  13. ❎ SOLD NIB White's TDI Beach Hunter With Li-ion Battery For Only $900 Shipped

    I believe that the TDI BH has a voltage regulator that controls power to the circuitry. Others have posted an increase in depth and performance when using a 14.8V battery, that's why I bought the battery.
