BlackTip Batteries

[RayfromTX]

I ran mine for a hefty part of my 5 hour dive today and still had 2 bars on the battery and 3 on the scooter. I estimate I mostly used speed two and three and probably was on the trigger for two hours. 12ah dewalts

Hello everyone, I am considering using an electric bike battery for my BT (one pack : 36v 20ah).
As a result, the blue wire which is used to control whether the two usual 18 v PTB packs will become unnecessary.
Would I have to download the latest firmware to turn off voltage monitoring between the two packs?
Thx.

Question: are the two Blacktip batteries wired in series or parallel?

The two PTB (Dewalt, Waitley, etc.) are wired in series. Personally I use Dewalt 12 ah.
But I want to replace this two packs (18v 12ah each) by only one big pack (36v 20ah).

althought, as an e-bike, this shouldn't be an issue..but just to be safe, you might want to check the current rating of the battery to make sure it's fine(again, I can't imagine a 20Ah pack not being able to handle max 24Ah..but better safe then sorry)
Also, how about the weight etc? I saw on the facebook group for divex, Jerry built a custom battery including holder for the BT

Surprised that you don’t see PTB batteries on e-bikes.

It's ok for the weight (about 3 kg) and the pack will fit in the tube (200mm x 120mm x 70mm).
In addition, the battery can deliver 30 amps continuously.

Well, then go for it. Worth a try

Anyone heard about this new battery from DeWalt:

• DeWalt DCB615 15Ah FlexVolt Battery
• DEWALT FLEXVOLT® 20V/60V Max* 15.0Ah Battery - DCB615 | DEWALT

Could potentially extend quite a bit the range of the Tech & Travel Scooters.

Will they be compatible with the scooter ?
