chad_gates Posted October 27, 2015 Report Share Posted October 27, 2015 Hello from Scotland, I have just acquired 2x 20.0s and now realise that I'll be needing a second set of batteries. I'm not yet ready for lipo. I see I can buy from Oset at £39.99, or from intamicro https://www.intamicro.co.uk/p-653-rec10-12-yuasa-battery-12v-10ah.aspx for £24.99. probably elsewhere too. As I am buying two sets, the price difference is significant. Anyone know a reason not to go with the cheaper supplier? Also, what is the perceived wisdom regarding off-bike charging? I was thinking of buying a socket like on the bike and simply attaching it to the batteries. Can anyone point me to a source for the socket? Can I balance the current and future batteries by individually charging them using my newly created shorty charger cable? Can anyone recommend a handy volt meter that I can easily keep close to the batteries, to help me check them regularly? I'll need 4. I also note I'll have to buy lanyards for the bikes too. I read previous posts about saving £25 with a DIY solution, has anyone any further/better advice to help? Many thanks, very impressed with the bikes. Cheers, CG Quote Link to comment Share on other sites More sharing options...
gwhy Posted October 27, 2015 Report Share Posted October 27, 2015 (edited) if they are the same make and capacity batteries then there is no reason not to buy them. yes you can charge the batteries off the bike . not sure what socket they use i will try to find out .. you will only need 2 voltmeters if you want to monitor the 2 sets of batteries .. ebay sell a small standalone 15-120v dc waterproof panel voltmeters for around £4 each.. you could wire them into the bikes permently ( use a small fuse ) , http://www.ebay.co.uk/itm/Waterproof-digital-voltmeter-DC15-120V-12v-24v-36v-48v-72v-99v-Volt-Panel-Meter-/321547865324?hash=item4addbf0cec:g:hfsAAOSwajVUN5A6 edit: this is the socket that you need http://www.maplin.co.uk/p/maplin-3-way-audio-locking-connector-chassis-plug-fm51f the picture show a higher in count you only need a 3 pin type, you could prob get them much cheaper from ebay.

chad_gates Posted October 27, 2015 Author Report Share Posted October 27, 2015 Many thanks. I was thinking 4 voltmeters, one for each battery pack (2 bikes, 2 spare sets). Can (should?) I use the provided charger to charge the batteries individually? Many thanks CG Quote Link to comment Share on other sites More sharing options...
gwhy Posted October 27, 2015 Report Share Posted October 27, 2015 just get a small cheap mulimeter ( around £5 ) thiw swill be good enough for testing battery voltages, you dont what to keep something connected to the batterys if they are nor being charged or discharged.. the small voltmeters are good to have pemently fitted on the bike as it will be a good indication .. i.e like a fuel gauge Quote Link to comment Share on other sites More sharing options...
breagh Posted October 27, 2015 Report Share Posted October 27, 2015 Hi Chad, I too run a spare set of lead acids for the wee boys 20 racing. Always charge them on the bike but I reakon I could swap them in less than 2 minutes. Did away with the fiddly battery bag and use heavy duty reusable cable ties to keep everything in place. Dont know if this is good practice but the bike does get used under trial conditions with no problems. Maybe see you around. Cheers the noo.
