Thanks for the reply Ed. I forgot to say, this pack is Ni-Cad. I have a 2400 NI-Mih 6V pack here, just use it for bench testing. I am still old school on batteries for on board, stick with NI-Cad's. Received this pack from SR, put it on charge, using an Accu-Cycle Elite, the pack warmed up a little at end of charge. It was up to 7.14V, settled in at 6.75V after alittle use, and I am sure it will get to where it need's to be.
I am not an expert on this, or the battery charger, I just follow the manual charge instruction's. I am thinking, with the foam rubber on the bottom of the pack, and sitting on the styro-foam, I may be OK. If I have to, I can take the cross members out that I put in, do a total foam rubber wrap, slide it under the tank, secure so no movement, unless for CG change. Maybe I am answering my own question, but need input from you guy's.
