I guess the title says most of it... I'm a semi retired engineer who has taken the Covid19 opportunity to have a play with electric bikes. I'm dipping my toe in the water by purchasing an elderly broken bike to experiment with. The idea is to reduce the use of my car for local trips, motivated by environmental consciousness and parsimony. Unfortunately significant surgery prevents me from using pure pedal power in my slightly hilly home area.
The bike I have purchased is a Yamaha XPC-26 that appears to have never been used and parked in the dry. However, unsurprisingly the battery is beyond redemption and, there is no charger with it. I've temporarily grafted in a 24v SLA battery and pumped the tyres up and it seems to work. Now I need to remedy the ravages of time on the fittings but more importantly convert it to a Li Ion battery.
For the battery, I want to convert the existing casing to accept a 7PS6 array of 18650 cells which looks like it would fit and give plenty of range. I have managed to get hold of three spare battery cases so for the time being I am making a 5Ah SLA unit until I can sort out the more complex version.
Any advice would be welcome, particularly if anyone has a workshop manual.
