Hello don't give up on your Nicad packs it sounds like it needs a little conditioning and topping off, run it totally flat then charge then take it off the charger for a couple of hours and charge again, do this for a few cycles things should start to improve, also check your connections and wiring ...

Front or Rear?

I have made front ones and Team Hybrid stocks them also Kenny does make them as well (you will need a good one) the puma motor will bend 4 sheets of 3mm mild steel at the axle so it needs to be very strong.

Cheers

Hello I tried expensive and cheap ones and they all sucked big time, good for about 5 mins of hard use and thats its, I can squeeze 15Ah measured! from my Nimh with careful use, ok I dont do this often for obvious reasons but it you treat NIMH well you can, 15Ah is 3 times what I got from a much hea...

Hi The best way to get good range with SLA is to take them out and put something else in instead. I never had any joy at all with lead acid batteries they are way too heavy, you can only get half the rated capacity from them, they are ok for the first 5 mins of hard use and thats all. They are ok fo...

Hi Guys Yes its a nice cheap old battery this one!! ha ha and it is not bad for the money, I haven't loaded it up yet to try it but I am pretty hopeful it will be ok. I can probably get inside to look at the cells but there is no need as the supplier will tell me and or show me the photos. It will b...

Hi Xyster Yes I stripped one of the pumas down after about 500 miles of abuse and its perfect inside and out, the nylon gears look a1 no problems, the only bit to wear is my home made torque arm that has taken a battering, it shows you how much torque the thing is putting out if it can bend 4 pieces...

Hi Xyster I think NICAD is still a good buy as well, it tends to be heavier and bigger but its cheaper than NIMH and dishes out big amp surges better, however it is not very earth friendly, it isnt banned here in the UK its just harder to dispose of legally. NIMH seems Like Larry said to be on its w...

Hi I like the look of these, id like to get my hands on one with some Lipo and boost the motor up, you can run cheapo brushed motor controllers on these which is good as they are brushed, I dont think its a candidate for a straight swap for a power pack as the motor shaft is different. So id look at...

Yes Good idea a friend did this he hid AA cells totally inside a bike frame!! amazing job he did getting them all in. It may be a good Idea though as you will have paralell banks of NIMH to put in a power Diode between packs as I assume that you will be splitting them. Lithium is coming down in pric...

Hi Larry Yes the point-1 and the ev tech packs are the same thing, I dont know too much about these packs as its a little under wraps whilst I am testing them but pricing should be under the existing packs which is good considering these packs are true 15AH packs (20AH with a 15AH shut off) so for s...

Hi Safe Those figures for the bike sounds mighty impressive given the weight of it but you are right they tie up perfectly with the online calculator here http://www.kreuzotter.de/english/espeed.htm Its amazing isn't it the efficiency of recumbent bikes, you hardly need any power to keep them moving...

ride

Hello Safe Cool ride!! like that a lot, can see a nice upgrade in the NIMH that's a great Idea for sure, neatly turned out machine the lack of peddles would lead me to getting pulled on it around these parts but I am sure your cops are more forgiving than ours. 60mph will take quite a lot more in th...
