Securing Batteries

[Buoyhunter]

Hey guys. Looking for info on holding batteries into the boat. what are some ways to do this? ive seen the velcro wrapped around the battery. i see this needs to be really strong to hold the batts in in case of a flip. any pics or info would be good.

Velcro under the battery, or a battery wedged in place with flotation foam works for me.
