I had a chance to purchase 24 actually 28 NEW Grade A LifePO4 batteries on the cheap so I bought them. What problems can I expect building a 72v pack using 24 of them? I have read on here about using, a good strong tape around each set or group of batteries. Any suggestions on put this all together so I have a safe setup? The GEM dealer said I should expect about 70± miles with this setup.
