Wow look at those big batteries..I bet they can provide a lot of current.. they still use these SLA batteries in a lot of mobility transport vehicles don't they..Thanks to everyone who responded. Esp d8veh for letting me know that I'd need to change the controller if I upped the voltage. Changing the controller might place me out of my depth... there's an awful lot of wires & if they aren't a perfect match for my existing controller I'd be screwed! Also I forgot to mention my bike is a 200w model (I assume that means a 200w motor) and the lowest wattage I've seen for a 48v controller is 350w.
Despite differing opinions on which technology I should use, the consensus appears to be that switching to Lithium won't cause any complications (apart from wallet shrinkage) so thanks for all the advice.
I think I'm going to plump for a Ping because of his general reputation. I'd like the 20Ah unit but I'm thinking 15Ah on cost grounds.... Does anybody think that this WON'T be sufficient for getting me to work (6miles on level, 0.75 miles moderate climb) & back again?
Anybody who owns a Ping battery, what sort of terminals does it have?
My current pack (pictured) just has wires soldered to drilled tabs. It also has a reset button in the circuit - anybody know what that is for?
I don't know about Ping battery's but mine (also from China) have IEC connectors (kettle/PC type) on them so you can just make up a cable with a female IEC or put one directly onto your controller power leads if it's long enough, without needing to solder.
