I use old golf cart batteries bought at car boot sales, sealed gel packs, great for 5 hours or more on the magnet, as for charging, I bought a very cheap charger from China, 12v-2 amp, fully charges overnight ready for the next day, charger cost around £5 free post, and batteries usually go for around a fiver.
