Respected members, just joined the forum after months and months of being a non member but keen reader of posts on this forum.

I had a 36v/48v 1kw direct drive mountain bike with 36v 15ah battery until recently (sold it) but developed interest in torque sensing mid drive TSDZ2. I have bought a slightly used but very well maintained Voodoo Marasa for a conversion project and bought the TSDZ2 kit with VLCD6 from PSWpower. I have seen quite a few videos for this kind of conversion and it seems quite straightforward. That being said, i absolutely suck at electronics (not good with mechanics either) so this noob needs advice and possibly some help (understandably not for free) with few things.

Any advice or help (if you are based in London) will be greatly appreciated.

1) The motor has bullet connector with fairly long cable. After bike and motor, I am on a tight budget so considering the batteries in URLs below.

OR

OR

I want to mount the battery in a bag on top tube (if you could advise for a suitable bag with holes for cable management, it would be super helpful) . Even though all batteries seem to have same or similar specifications, they vary massively in terms of price which is making me a littl uneasy. I would not want to want to deal with exploding batteries so please advise which one I should go for. In future (once i have some extra cash) i would go for a cleaner install with side release Hailong 2 perhaps. I have shaky hands so would not want to go for soldering hence i should perhaps go for a battery with XT60 female connector and get a bullet to XT6 male adapter. Let me know if you think that is a bad approach. Long range is not a massive concern. My commute is roughly 11 miles each way but I have the flexibility of charging at work place.

2) For now i will stick with the stock chainring of the motor but might look into changing to the dual chainring 44t/36T? in future . Considering that, i would ideally like to keep the derailleur so that there is then less to do ? Is it possible ? let me know if its a bad idea etc.

3) I don't have the tools etc plus I am terrible so if a pro or experienced person can offer build service for a good price, i can consider that too. The one i know of in London is based in Greenwich called Besbike and charge £160.

In addition to the above, any advice or anything to be careful with or advice would be greatly appreciated.

You will have to pay duty on all of them, being batteries I don't know how much though plus a handling fee by the courier.

It's one thing most buyers don't facto in properly they but a motor but then skimp on the most important item, the power supply.

I suppose duty etc is to be expected. could you recommend or point me to a UK based seller for similar item ? I was hoping to buy a base/donor bike for cheaper or finance but then found a marasa for good price to ignore and ended up paying lump sum and messed the balance.

You will need to look on ebay or to Germany/EU.
Have a look at enerprof.de.
You will need to look at about £300 and get a decent celled battery that way it can be a hard case frame mount rather then a softpack in a flimsy triangle bag.

I tried that (with 44/34) but it was more trouble than what its worth. The trouble is it pushed the 34T chainline outwards by 5mm (over and above the existing standard chainline) and the 44T by a further 8mm (13mm in total), so that the chain has to cross over too far to get to bigger cogs on the back. Furthermore, the standard derailleur wont reach out that far. Also trouble fitting chainguard. Anyhow, I put back the standard 42T chainring as I was happy enough with getting the lowest rear cog (34T) working well without too much chain crossover on hills.

Thanks for the advice mate. I'll stay clear of the trouble. Guess the standard 42T should be enough for me anyway.
