[Brian MorrisParticipant @brianmorris30448]

i have bought a new4300ma nimh 7.2vbattery charged it with old acoms charger .but it only lasted 5 mins before it drained down . which is the best charger to use on this , and together with charging the transmitter and reciver nimh batteries . is it best to drain completly with a light bulb which i used to do with previous r/c plane batteries . is there a bargain charger on the internet ??

Hi Brian. I purchased an "omni" NiCd/NiMh charger wot caters for 2-10 cells off the jolly old..dare I mention it., E-bay jobbie.. It seems to work ok,  If in doubt buy something from a specialist battery supplier. The price varies quite a bit in my experience of surfing for the bargain, I would be doubtful of extremely cheap chargers tho`(on general principle). This one is switchable for various voltages and is automatic (so it switches to trickle charge when it senses the batts are full) so it will do my main and transmitter batts. NiMh cells do not have "memory" so do not need discharging fully. It is my understanding that they take a few full charges before they attain thier ultimate capacity. My personal preference is not to fast charge batteries. i am new to nimmies as well, my experience is mostly gel lead-acids, as my boats up to now have been capacious enough for them..   Ashley

Hi brian

   I good charger I can recomend is the " Swallow ac/dc 2 " it really is a top charger.

    There is no need to flatten or drain NIMH batteries as there is no memory effect with them and also the above charger will recycle
