64ragtop - that is the battery - like you say it should have worked the motor is sealed - so nothing could get inside all wires are fine i can hear the motor tops out at about 19/20mph when i pedal and again it used to top out about 21/22mph it has actually got a little better in the last...

nimh were in series - 24v yes it is a brushed motor motor still works fine - just a little slower sla were fully charged before i stopped using it for a few months and the system worked well then (19mph) so then after the swap and then back again it now goes a little slower (3mph) wireing...

perfect i actually figured it out for myself last night and ive just logged on now and got the same answer as what i did i tested a 1.5v battery first to see what happened with the minus sign when i was confident i did the same with the charger ive used the digital meter before so i...

thanks for all the help guys 1 question what exactly do i need to do with my DDM (voltmeter) to figure the polarity out a nice idiots guide would help thanks Alex

hi i have taken my currie electrodrive box to bits to try a new battery system well the results were poor so ive decided to put the old sla box back together ive got it all back together but when i first took it appart i cut the wires off to the charging socket - and now i dont know how to...

let me know how this goes and what you end up doing as i may want to do the same thanks Alex

Super helpfull guys ill get the nimhs and give it a try thanks for the info everyone Alex

i have a 24v system and the controller has a sticker on it saying "max voltage = 26v" ive took the box appart and there are a few capacetors with 25v on them and there are the black components that are attached to the case but i cant see a voltage on them i want to run 2 x 12v nimh insted of 2...

yeah i saw that thread but i didnt know what effect only running 2 batterys in series would have it says the batterys can handle 30 amps - i think thats about the max for my setup so i assumed it would be fine i might just get 2 and try it at £50 even if it didnt work im sure id find a use...

THATS GREAT Do i need to worry about voltage sag? bear in mind the system is currently using 2off 12v 12ah sla im also guessing that it is a claimed 3700mah and probably more like 3400mah i think i can manage the maths now but a reply about voltage sag would be super cheers Miles

thanks for taking the time to reply im really after someone to work out the maths i dont want to go a reasonable distance - 3miles max 2 miles would be ok can anyone tell me how far id get before loosing power using these batteries? thanks Alex

Hi will my 24v 450w (peak 750) brushed DC currie electrodrive motor get me 3 miles of flatish road using 2 x 12v 3700mah vapextech r/c nimh batterypacks hope you can help thanks Alex
