I looked through the list of forums and did not find one specific to batteries. So I'll ask my question here. I have four Promatch 1S 5000mah 40C batteries that are at least 3 years old and have not been used a lot!!!! probably the biggest problem, I also have several Team checkpoint 2S . They have always been stored with a storage charge.
I would like to cycle and test them, like we used to with NIMH'S at a 20 to 25 amp discharge rate. My I Charger will didcharge but at a very low rate
Is there a specific discharger I can buy or is there a home made version I can build, like the old bulb dischargers we all had. My last resort would be to send my Turbo 35 in to get it upgraded.
