I bought these 2 in March of this year to put into series for my 24V system, saved about $100 instead of just buying a single 24V200Ah battery. Not to mention the size of a single Ampere Time12V200Ah battery is nearly the same as a single Ampere Time24V200ah battery. They've been cycled maybe 200 times tops, never below 10% and my CC is set to 28.8V. Bottom line, these have been barely used. Letting them go for $500 each. Local pick up preferred, you can see them in action in my garage, and we can disconnect them, and you take em away. Or I can drive them to you. Not too far though please. Henderson, Las Vegas area only.
