    Can you get a 48v controller that you can set a wattage limit on?

    Do some motors not work with certain controllers? it's a 3 phase motor with 3 hall sensors, one of the hall sensors need replacing which is why I have a spare motor... the original seller sent me a replacement, but I'm pretty confident now that I can replace the faulty hall sensor on the...

    Can you get a 48v controller that you can set a wattage limit on?

    The spare motor I have and the motor/kit on my main bike are rated for 1000w but I've had no issues with the police on the roads... that's because I don't go any faster then 15mph and tend to keep my power draw below 300w anyway which doesn't draw much attention (the bike can cruise at 15mph...

    Can you get a 48v controller that you can set a wattage limit on?

    I was going to build a DIY battery for another bike but rated continuous power of the new battery will be around 300w, it's a budget bike but I also wanted the option to upgrade the battery in the future which would allow for a higher power output. I already have allot of spare parts laying...

    Best voltages and methods to cycle lithium cells between?

    I use a multimeter to take messurements (and also to make sure the battery isn't overcharging) and divide the total pack voltage into the number of cells within the pack (54.6v / 13 cells = 4.2v per cell)

    Best voltages and methods to cycle lithium cells between?

    I've read it you cycle a lithium cell between 100%-0% you might only get 500 cycles while if you cycle between 10-90% you might get 2,000 cycle and 20-80% could get 5,000 cycles. and some claimed if you cycle right in the middle of the cell you can get upto 20,000 cycles! Does anybody know the...

    can you get adaptors for different chargers?

    Thanks allot for your help anyway guys! I only just started using my ebike... do you know how to work out your range? I just did a 27 mile ride today (measured using GPS) and I only used 1/4 bars (on the LCD display) and my battery is measuring 50.4v and it started at 54.6v. I can't imagine...

    can you get adaptors for different chargers?

    I've charged the battery twice now it seems fine. I've covered all the wires/connections with electrical tape and made sure there's allot of clearence and isolation between the wires incase a solder joint fails. Also, If I plug the charger into the socket before the charger is powered up it...

    can you get adaptors for different chargers?

    yes you was right... I checked the continuity with a multimeter before I read your comment but If I didn't have a meter there would be no way to know! :D Thank you. :)

    can you get adaptors for different chargers?

    I'm not sure i'm happy with how thin the wire is but it wasn't getting hot while I was testing... although the battery is at 52v so it's probably not charging at 2 amps. I'll have to keep checking for heat when I next charge the battery when it's low

    can you get adaptors for different chargers?

    I might just make an adaptor my self, I have a DC port and a standard audio RCA jack fits the charging port just fine... I used a calculator and for a 20cm peice of wire (that was the as low the calculator length would go, the actual length of the wire will only be about 5cm) and it says it only...

    can you get adaptors for different chargers?

    I take it you can just unscrew the metal casing and just attach the new cable? I'll have to look into it in the morning. Thank you! :D

    can you get adaptors for different chargers?

    Due to a shipping mistake I have two chargers one with an RCA connection that fits my battery and the other has a standard DC power connector which doesn't fit I wanted an adaptor for the charger with standard DC because it's a better quality charger, it has a built in fan and has the same...

    is it possible to use this lead acid battery with a conversion kit?

    I've ordered the kit with the 48v 15AH (~720Wh) Lithium-NCM battery... it should be delivered within the next week or so! hopefully it all goes smoothly :)

    is it possible to use this lead acid battery with a conversion kit?

    my bike is a hybrid with 700x28c clinchers tyres.... i'll probably stick some decent 700x35c cyclocross tyres once I get the kit (i think the rim in the kit is slightly wider anyway).

    is it possible to use this lead acid battery with a conversion kit?

    I'm thinking about buying an electric conversion kit for my bike but I'm rather confused how I would use this battery and charge it up (I'm new to this!) here's the battery... http://ebay.eu/1qORcqc it's originally for the Mach 1 E-scooter This is the kit I was thinking about buying -...
