THE BASS COLLEGE

I want to get another battery for the crawdad but don't want to spend another $50 on a second charger is there a way I charge and maintain two batteries on one charger? 

i would think you can run a jumper wire , it would just take longer to charge. ive never done it so check into it first. i have a jumper wire on my 36volt system but thats to link the batterys together  not to charge them i have a 4 bank charger for the 4 batterys in my boat. i think it should work , check your amps on your batterys add them together and if you have a 10 or 15 amp charger that will tell you how long it will take to charge
