[Ten times the size of the one on Cat's biggest bulldozer]. Charging a 25 AH battery at the fifteen minute rate has to be a poor idea. Rule of thumb given to me by an old time Trojan application engineer: Recharge rate = 15% of total connected AH rating of bank. Based on 2000AH bank, it will accept a 300A recharge rate without complaint. Every 100AH consumed requires 125AH replacement. Yes you can play games with the above, but it will come back to bite you. Wet cell battery technology hasn't changed much in the past 100 years, it is a very mature product. Lew |
