These guys give good service in my experience, http://www.electricmotorsport.com/store ... _parts.php
750 watts = 1 HP, so 4 hp motor is 3000w, 10HP is 7500 watts.

I'll be there too, probably portage up in a van, 40 miles range, so will need a recharge (2 hours also).

Hmm, I'm just about to set too on an outboard conversion myself. Other choices for motor are the new "Etek-r" and "-RT" motors, or even a Perm 132 is cheaper than a lynch I believe. Cheapest of all is the "mars brushless etek", with the added bonus of no brushes to wear...

Its already got a low voltage cutout on the bike (each cell monitored individually) Good to hear the rest of the pack looks OK :) What sort of LVC have you got on the pack, is that homebuilt as well? Just curious as I want to build a small foolproof A123 pack for my wife's bike. It is a homebuilt u...

In my opinion lifepo4 will last the distance if properly treated. Even a PB battery will suffer and die if over discharged, or not recharged immediatly after use, I've got far more dead PB batts than lifepo4's sitting around the workshop! Also, the quality controll of thundersky cant really compare ...

Its already got a low voltage cutout on the bike (each cell monitored individually), and I have a homebuilt balancer I use every few cycles. I was just testing one part of the pack when this happened (the A123 segment). I ran a few full discharges on it today (much more carefully), and the rest of t...

Your way sounds rather longwinded, I found a quicker way this afternoon.. I wanted to test capacity of a large A123 pack, so I connected a meter and a load (bank of big bulbs) and sat back to watch whilst I worked on the next pack. I watched the voltages all the way down...till a customer called and...

I'd like to come along too and bring the E-Aprilia motorbike, I think I may be able to encourage a couple of electric KMX riders to make the attempt too:) Most important of all, I live 10 mins away from Brighton, and can offer multiple charging points with space for several cars (with appropriate ex...
