I have bought a standard MAC kit from Paul (cell_mann) and I’m really happy with it (not in the least as a result of the good info and help from people on this forum).
My battery is a 12S Lipo pack (3 x turnigy 4s 5000mah hardcase bricks) and I am charging it with a 106B Icharger which also works fine.
I have found though, that I like riding the bike much better than charging it: I have been balance charging the three bricks individually, so that takes a fair bit of time and attention.
So I’d like to move over to bulk charging and maybe once a week do a parallel balance charge and check the individual cell voltages.
A few days ago I came across a post from ‘dogman’ advocating a 14S pack (by adding a 2S to my existing ones) and then using a charger like the 58.8V / 5A charger from EM3EV for bulk charging. I quite like this idea, but have a couple of questions:
- I have the standard 6 FET, 25A controller from EM3EV which supposedly can handle up to 60V. Will running it at close to 60V regularly shorten its lifespan?
- The next step then would be to use a BMS and make my charging life easier again. I could either get one from EM3EV or from Bestekpower. Which model from Bestekpower is the best for this setup? (also price wise).
- If I then at a later stage want to increase my capacity / range from 5Ah to 10Ah ( by buying another 3 x 4S bricks and another 2S) how does it work with the BMS then? Do I have to buy another BMS for the new batteries and run everything in parallel?
