Re: kWeld - "Next level" DIY battery spot welder

I keep blowing my lipos, will i reduce the time required to make the weld by increasing their voltage? And there by reducing the heat and stress on the thin aluminum terminals Im currently at 3s and can make a 5s batters from the cells I have left that are not broken (all the same 5ah 75c panther) ...

All the cell level and pack level voltages are set very conservatively (ie low) at around 3v a cell,
You should explain some more what does it mean or post a picture of the BMS setup

East coast rules.

Basically ride anywhere no one cares. Blank stares or ignored most of the time.
Hummm, here in West cost of Tuscany I would say also pedaling no more than 30 mph nobody care of you.
Is it ok at any speed for you?

Re: E-S Stealth Electric Bike Owners

last Saturday with a friend of mine who has a mid drive e-bike I took the longest trip ever with the Bomber. 20190511_172604-2.jpg I did 35km off-road but the slopes of the hills near Pisa are 30km away from home so I covered 60km of transfers and I arrived 5km from home with the battery exhausted. ...

Re: Adaptto Mini-E/Max-E Owner's Thread

I'm going to give this a go. I think lack of responses means that nobody sees any issue with it and I'm not overlooking anything. To make the question more simple, would anyone see any issue with having the max-e main battery wires connected to one battery, while having the BMS connected to a compl...

Re: Adaptto Mini-E/Max-E Owner's Thread

The first thing I noticed as I got this BMS is that it was balancing worse (maybe it pulls too little current to balance the higher cells) than my iCharger 1010B+ that balances up to 10S in a very accurate manner also if the cells are pretty old and degraded. It was with my older battery made with L...

Re: Adaptto Mini-E/Max-E Owner's Thread

You are having a strange behaviour with the firs cell always greater than the following 3.
I found out that using silicone wires on the 4S JST-XH connectors helps to relief the stress on the BMS.
