Maintain up to 8 batteries at the same time with a single BatteryMINDer charger. The 210AY daisy-chains batteries in parallel using industry-standard SAE bullet connectors, so every cell stays conditioned without moving clamps or swapping leads. Ideal for RV house banks, dual-battery tow vehicles, stored boats, and seasonal equipment.
If you run a multi-battery house bank in your RV, or store several vehicles over the winter, the 210AY lets a single compatible BatteryMINDer unit maintain all of them simultaneously. No splicing, no separate chargers -- just plug the connectors together in sequence and let the charger do its job.
The harness uses the universal SAE "bullet" standard, so it mates with any BatteryMINDer output lead as well as most aftermarket battery tender pigtails already installed on your equipment. Protective caps on every connector prevent accidental shorts when leads are not in use.
Replaceable inline fuses on each branch protect against short circuits. If a fuse blows, swap it -- no soldering, no rewiring.
Industry-standard SAE "bullet" ends with protective dust caps on every connector. Mates directly with BatteryMINDer output leads and common pigtails.
Daisy-chain up to 8 batteries depending on the BatteryMINDer model in use. Scale from two batteries to a full bank without additional hardware.
Backed by a 1-year 100% money-back guarantee and a 5-year no-hassle manufacturer warranty from BatteryMINDer.
The 210AY is an official BatteryMINDer accessory engineered to work with the SmarTECHnology family of battery chargers and maintainers. The number of batteries you can connect in a single session depends on the output capacity of the specific BatteryMINDer unit being used -- check your charger model's documentation for its maximum supported bank size.
Each of the three inline fuses is a standard replaceable blade or glass-tube type rated at 15 amps. If a dead-short fault occurs on any branch -- for example, a pinched lead or a terminal left uncapped -- the fuse on that branch opens before damage can travel back to the charger or to the other batteries in the chain. Carry a spare fuse set (standard 15A automotive fuse) and you are covered roadside or in the field.
