Thanks for that guys. I think i will stick to FLA for this purpose. just hoping to get some more use out of my larger ebike batteries I've got a 85ah 12v FLA so just getting a victron MPPT controller.

Hi John, I don't have much experience in DC conversion. I understand it's lossy (not efficient) to change voltage but what is fragile about it? I am trying to save money by using a large battery I already have to set up a system. Do you think it would be "less lossy" to setup an inverter off it...

Hi John, we have another system on the boat for charging other stuff so the bike battery will be used exclusively for the 40L fridge and loading I have mentioned was from someone using the fridge at 12v at 32 degrees which is midsummer temps for us. Sent from my SM-G950F using Tapatalk

ALSO Any comments/recommendations on whether Sunpower Maxeon solar cells are worth it? I was looking into getting a solar blanket but it needs to be 20v open circuit voltage to be suitqable for the solar controller mentioned :bigthumb:

I'm looking at a compact setup for island camping with a 52V 20ah (14S7P) EM3EV battery I have to charge a 40litre fridge from solar. My question is will the following setup work? and are my calculations right? CALCULATIONS Battery - 52V x 20.7 ah = 1040wh (use 1000wh) (8A max charge current @...

Seems that I may have to fit a couple of diodes but not sure what my discharge control FETs are rated for. Sent from my SM-G950F using Tapatalk

Milwaukee 18v some 4 some 5ah Sent from my SM-G950F using Tapatalk

Thanks guys Great info, I have had a good look at the bmsbatt kit which would fit nicely on the 16in rim. Just wondering what you think the issue would be with putting 2x 18v in series for 36v? Already having the batteries and them being smaller (4 or 5ah) makes them much easier to fit the...

thanks for the link Motomech is it possible to modify the throttle with resistors to adjust the span until she gets used to it? and also any tips on estimating the spoke length? Or is it easier to buy long and cut and thread it myself?

Hi guys I am endeavouring to convert my daughter's byk e-350 with a front hub motor and either 18/36v (one or two drill batts) How would this kit stack up? I need 100mm dropout on the front and my rim is a weird 355mm. I think i This may be 18". Not sure what size rim to go with. Lots of 12"...

Hi guys I've been thinking lately, wouldn't it be nice if my battery bms or charger could alert me when my battery was finished charging. I'm assuming that there would need to be a sim card pcb added to the bms or charger to allow this to happen. Has anyone attempted something like this...

Great info guys, It ha got me thinking, would it be possible to over volt my mm G330. 350 from 48v to 52v? Or would it be worth changing controller to do that?

Thanks MalcomG Very nice install. There are a few steps to go before we install the electric motor and I will use this post for reference. The bike's gear selector was very sticky and the handlebars are very narrow but we dropped it off for our mates and I will send them the link. They are...

So far I suspect the display as no blown mosfets on the controller and getting throttle 0-5v feedback from torque sense cable (red 5v, black 0v, grey signal 0-5v) BUT getting good power return on the right pins and no shorts (used Luna BBSHD wiring diagram) from the display so cabling from...
