bit more money but more AH
Actually that second one is cheaper as well as having more Ah
Its got a higher postage certainly but since the price of the battery is not as much as the 2.1Ah one, it works out cheaper overall for the higher capacity battery
looks very heavy, just wanna get summat up and running for the guildford even then im gonan build my fw drive axe robot.... or maybe i shud wait lol
oh quick question has anyone got a spare servo for a skysports? if ya have gimmie a price gonna run my axe on the crude bang bang system
Id be cautious of buying batteries from like these they will only casue problems, better to pay the extra few quid and get a known good one. cpc.co.uk do some good priced lead acid batteries that you be sure are in date.
The second one looks dodgy as a 12V battery that only reads 12V when not under load is nakered. The first is from a sercurity firm so even they claim its new the chances are its old stock and Pb batteries only have a limited shelf life.
Stock number BT00101 from CPC is £15.86 including VAT, same type as the first and if you spend over £40 delevery is free. Both Farnell and RS do the same battery and you can check what the postage costs are. Not sure but farnell used to do free delivery without minimum orders but this might have changed.
Ant, Ive got several similar SLAs 12V 2.8Ah or whatever they are. Old but you can have them if you want, not going to post them however but I will bring them to the next event.
buy 2 7.2v nicads from a modelshop and take some cells out there something round 15 quid and will last ages and could be used to another robot in the future
just a thought...
ed that would be awsoume im at guildford event if u are?
Should be, see you there.
