Replacing/Adding a 36v Battery. (Lots of pictures for guidance)

£3 gets you a useable soldering iron on Ebay - a lot cheaper than a crimping tool. You want 60/40 tin/lead solder.

That bloody cheap? Wow! Thanks for the ratio quantities too.
I haven't ordered anything yet, but I think It might be worth just disgerading the crimping tool and soldering instead. This way I can use the XT60 connectors rather than the Anderson Powerpoles.

The battery I'd be buying is connected with Anderson Powerpoles, however, It shouldn't been too hard to remove this and apply an XT60 connector correct? As long as I treat the battery wire with great care I should be safe I'm assuming. (I.e. Soldering only one wire at a time)

Forget crimping. Unless you spend a lot on a decent tool, it will not give satisfactory results and you will probably destroy several connectors before you get it right. You are bound to need a soldering iron for other things before long, so it is a good investment.

If you are soldering things like heavy duty cables and connectors, make sure it has enough Watts to provide enough heat on things that act like big heat sinks.

For £15 to £20 you should be able to get a 60W solder station with digital temperature control.

Yose Power packs I've found are ok in terms of the cells inside. I've had a couple of the Silverfish variety. However, some of the soldering inside of one of the packs wasn't good and it failed where the wire connected to the output fuse. Also, the key switches are not really rated for high power switching, so they can wear out quite quickly.

The one I bought in the last month has no key switch, in fact no switch whatsoever. Only a button to test for charge condition. Once in the holder it is permanently live. https://yosepower.com/collections/ebike-battery/products/36v-12-5ah-down-tube-battery

So... I ended up taking your advice and have decided to proceed with soldering. I've got all of the tools I'll need ordered apart from the actual soldering iron - i'm still comparing various ones. I've also ordered a 36v 17.5ah Triangle Samsung Cell Battery off UnitPackPower. I've seen a lot of good reviews of his batteries with samsung/panasonic/lg cells and they're at a decent price!
UPP was very helpful when messaging, they even put in an extra female XT60 connector for me! I know the battery isn't here yet, but so far I'm very pleased with their service!
