Hi,
This is my first post, so sorry if this has been covered. I have searched and I'm going around in circles.
So I'm getting close to converting my 1972 VW Bus. I'll be using a conversion kit from EV West, with AC-50 motor and Curtis controller. I'm fairly happy with the system, it's just the batteries I'm having issues with.
My first option would be 30 x 3.2 Lifepo04 100ah (30s1p) wired up to a BMS. This seems to be a safe option and looking at other project should get me 30-40 mile range. If I have the room I would ideally like to get it too 200AH so 32s2p.
The second option, which I'm just a bit jittery about, is going the 18650 option. I have no intention of using old laptop batteries, all cells would be new. I could make 48v 50Ah battery pack myself, or buy the same spec E-Bike batteries (from Aliexpress etc heres one on eBay http://www.ebay.co.uk/itm/48V-50AH-rechargeable-Battery-Pack-Lithium-li-ion-ebike-EVs-BMS-20A-max-charge-/263205445934?hash=item3d4844612e:g:BKsAAOSw42dZN2XG ) and then connect them together, 2s2p, or budget willing 2s4p giving me 200Ah. They would all have there own charger, and have BMS's Would the premade E-Bike batteries standup to be using in this way. The gauge of the wire seems quite small, and would it be pushing to many amps through the batteries in series?
This area is such a black hole to me, and I'm very aware of how much of a fire risk it is, so I'd like to get it right. Not to mention the money involved!
Any ideas?
