Rather than start a new thread, im looking to replace my batteries in Conundrum Mk2 before the champs, what do people recommend I get and where from. Keep in mind that I am running a hungry Ev warrior and a couple of drill motors, at the moment it seems to run ok on two heavy 3Ah 12v BotPacks, just want an upgrade.
Chris - ^_^
I am having a problem charging my batteries . I have a modified PSU and a Pro Peak constellation charger . When ever i want to charge my 3300mah 24v pack at anything over 2 amps i get an error message saying Input Voltage 11.60v Is there a solution to this ?
get a better powersupply, the amps drawn from the PSU make the voltage sag beneath the minimum value of the charger hence the error
Thanks alot Tim , Does anybody know any good power supply units ?
We had this problem with three different power supplies that we tried. In the end bit the bullet and bought a big one from Rapid Electronics. Many teams use the same one. (order code was: 85-1828) Cost about £110 inc del.
Chris stick with the botpacks if you can otherwise, race packs/indivual cells, if your confident of making up good packs, of GP3700 NiMH
If you go to chargers and PSUs at http://www.technobots.co.ukwww.technobots.co.uk - both the 13.8v 20amp Power supply (1090-016) and the 13.8v 20A Dual Output Power supply (1090-017) are both ideal not to only run 1 of your chargers at MAX ratings, but attualy 2. I think they say you need about 8 or 9amps supply to each charger for it to work to its max. So a 20amp supply will quite happily do 2 chargers. And the cheaper one at £34.12 which i use, does one charger perfect, and also ran 2 chargers without problems when people borrow the supply from me as well. LOL - *COUGH* Pete/Jonno *COUGH*.

We use one of the 40A power supplies - theyre £136 plus delivery from Technobots (so about £140) but you can get the same charger from Rapid Electronics for £109 including free delivery
